King’s Gambit
Coffee Co.
Step 1
Decide what you drink, how many people you make it for and what you'll spend before anything lands in a cart.
Most home bars go sideways in the same place: the machine gets bought first and everything else gets squeezed in around it. Flip that. Start with your drinks and your coffee routine, then build the bar to fit them.
Answer these honestly:
| Lane | Best for | Core gear | Tier where it usually starts |
|---|---|---|---|
| Pour-over station | Black coffee, one or two cups | Burr grinder, dripper, gooseneck kettle, scale | Bronze |
| Batch brew station | Pots for the house or for guests | Burr grinder, SCA-certified home brewer, scale | Silver |
| Espresso bar | Shots and milk drinks | Espresso grinder, machine, small tools, milk pitcher | Silver to Platinum |
| Travel kit | Camping, road trips, hotel rooms | Hand grinder, AeroPress or similar, kettle, scale | Bronze |
Tiers are rough budgets for a whole setup: Bronze about $150 to $250, Silver about $350 to $600, Gold about $900 to $2,500, Platinum $2,500 and up. Mixing lanes is normal; plenty of espresso bars keep a dripper on the side.
Step 2
Your bar needs four things close by: counter space, power, water and somewhere for the mess to go.
Pretty corners fail fast when the outlet is across the room and the sink is down the hall. Scout with a tape measure and a flashlight before you fall for a spot.
Islands look great in photos. Under the 2023 National Electrical Code, receptacles serving island and peninsula countertops became optional, with a way to add one later. Translation: a new island might not have power where your bar wants it. Ask before you plan around one. Behind any bar that moves fast, the work runs one way: beans, grinder, machine, knock box, milk, cups. Copy that line at home, left to right or right to left, and you'll stop crossing your own arms every morning.
Measure
15 × 14 × 21 in
That's height, width and depth for La Marzocco's Linea Mini, per its install guide. Not your machine? Pull the spec sheet for the one on your wish list and tape its footprint on the counter. Then add the grinder next to it. Counters shrink fast.
Reach
5 ft
The same guide caps the machine at 5 feet from its outlet and the drain at 5 feet from the machine, with the water supply suggested within 8 feet. Your model's numbers may differ. The lesson doesn't: plan the bar around where power and plumbing already live.
About $23
Cups shaped for latte art, sized to the drinks we actually pour.
About $45
Clear glass shows off crema and layers. Sold in pairs so nobody drinks out of the odd one.
Step 3
Coffee is mostly water, so the water you pour in is the biggest ingredient in your cup.
About 98% of a cup of coffee is water. Minerals in that water help pull flavor out of the grounds. Too few and the cup goes flat and muted. Too many, or the wrong mix, and acidity dulls while scale builds inside your machine. Chlorine brings its own off-flavors. Good news: you can test all of it at home without a lab coat.
| Measure | Target | Acceptable range | Why it matters |
|---|---|---|---|
| Total dissolved solids (TDS) | 150 mg/L | 75–250 mg/L | Overall mineral load |
| Calcium hardness | about 68 mg/L (4 grains/gal) | 17–85 mg/L | Helps extraction; excess scales |
| Total alkalinity | near 40 mg/L | — | Buffers acidity; excess dulls it |
| pH | 7.0 | 6.5–7.5 | Near neutral |
| Sodium | at or near 10 mg/L | — | Too much reads flat or salty |
| Chlorine | 0 | 0 | Carries off-flavors into the cup |
As reported by coffee-water references citing the SCA standard. Sources disagree: some quote the older SCAE chart, with calcium hardness 50–175 ppm and alkalinity 40–75 ppm. Treat it as a target zone. Your machine maker's spec wins.
Test before you buy anything. Water is the cheapest fix in coffee and the one people skip: a cheap TDS meter and a pack of hardness strips will explain more sour or flat cups than a new grinder ever will.
Whatever your number is, write it down. When a cup tastes off later, water is the first thing to rule out.
Hardness
0–60 mg/L = soft
The USGS sorts water by hardness as calcium carbonate: soft is 0–60 mg/L, moderately hard 61–120, hard 121–180, and very hard is anything above 180. The coffee target zone sits in soft-to-moderately-hard territory. If your tap reads hard or very hard, Step 4 is your next stop.
About $42
The lowest-effort water upgrade: cuts chlorine taste. A filter, not a mineral recipe, so know the difference.
About $240

Bronze

Cold brew is mostly water, so the water matters. Mineral sticks built for long, cold steeps.
Step 4
Match the fix to the problem your test found: chlorine, hardness or both.
There's no single best filter. There's the one that fixes your water for your setup. A pour-over corner on decent city water might need a pitcher. A plumbed espresso machine on hard water needs real treatment.
| System | What it does | Good for | Watch out for |
|---|---|---|---|
| Pitcher filter | Cuts chlorine taste; some soften | Pour-over, kettles, tank machines | Test after filtering |
| Under-sink carbon | Cuts chlorine and sediment; keeps minerals | City water, moderate hardness | Won't fix hard water |
| Espresso cartridge | Carbon plus scale control; BWT bestmax PREMIUM adds magnesium | Plumbed espresso machines | Set to your hardness; replace on schedule |
| Whole-house softener | Swaps hardness for sodium | Household plumbing on very hard water | Espresso can taste flat or salty |
| RO + remineralization | Strips most solids, adds minerals back | Very hard or problem water | Never run raw RO |
| Mineral packets | Builds water from distilled, to a recipe | Tank machines and kettles | Ongoing cost; not for plumbed lines |
Chloramine needs the right carbon: the Water Quality Association says catalytic activated carbon works best and suggests NSF 42 certification for chloramine reduction.
Softeners
~10 mg/L sodium
An ion-exchange softener stops scale by swapping hardness for sodium. Your water heater loves it. Your espresso may not: guides warn softened water can taste flat or slightly salty, and the SCA target for sodium is low. Softening water that's already soft can flatten shots too. House on a softener? Ask a plumber about an unsoftened cold line for the bar.
RO
95–99%
That's roughly how much dissolved stuff RO pulls out. Bare water like that extracts poorly, tastes flat and can be aggressive toward machine metals. The guidance is consistent: remineralize it or blend it. Done right, RO gives you total control. La Marzocco's Australian support page recommends RO for best machine performance.
Packets
1 packet : 1 gallon
Third Wave Water's directions: one packet in one gallon of distilled water, shake until dissolved. No distilled? RO, deionized or zero-type filtered water works if TDS reads below 10. The Espresso Profile has no chlorides and was designed to protect machines from corrosion. The Classic Profile is for brewed coffee.

Cold brew is mostly water, so the water matters. Mineral sticks built for long, cold steeps.
Step 5
Every coffee bar makes wet waste, so decide where it goes before it ends up on the floor.
Spent pucks. Drip trays. Steam purges. Rinse water. A bar without a plan for the wet stuff turns into a towel pile by Tuesday.
Most home espresso machines run on a removable drip tray, and a knock box handles the pucks. Drains and rinsers are upgrades, not entry fees. Add them when you remodel, or never. A tray you empty every morning is a perfectly respectable system.
Rinser
35 PSI max
That flush-mount rinser that blasts your milk pitcher clean is a plumbing fixture. One maker's install guide calls for a cold-water-only line, backflow protection that meets local code, pressure held within 35 PSI, and a drain connection with fittings sold separately. No drain under the counter, no rinser. Call the plumber before you cut stone.
Drain line
1/4 in per ft
La Marzocco's Linea Mini guide calls for a 3/4-inch flexible drain line with at least a 1/4-inch-per-foot slope, connected to a sink drain above the P-trap. A commercial installer's guide asks for a 1-inch drop per foot. Different specs, same physics: the hose has to keep falling the whole way.

Step 6
Espresso machines pull serious power and live next to water, so this step ends with a licensed electrician.
We're coffee people, not electricians. This step tells you what to look for and what to ask. It is not a how-to. Check with a licensed electrician and your local code before you add or change any circuit or outlet.
| Item | Number | Where it comes from |
|---|---|---|
| 15-amp, 120-volt circuit | 1,800 watts at full rating | Amps × volts |
| Continuous loads (3+ hours) | Usually held to 80%: 1,440 W on 15 A, 1,920 W on 20 A | Read from NEC 210.20(A) |
| Breville Dual Boiler | 1,700 W | Retailer spec |
| La Marzocco Linea Micra | 1,600 W at 110 V | Retailer spec |
| La Marzocco Linea Mini (original) | 1,620 W; 20 A full-load draw (14.6 A in half-power mode) | La Marzocco install guide (2015) |
| Kitchens under the NEC | At least two 20-amp small-appliance circuits | NEC 210.11(C)(1) |
Specs change by model and year. The nameplate and manual on your machine are the only numbers that count.
A machine pulling 1,600–1,700 watts uses most of a 15-amp circuit by itself. Put a grinder, a kettle or a toaster on the same circuit and breakers start tripping. One commercial installer says every commercial espresso machine should have a dedicated circuit, with the grinder on a separate breaker. Some prosumer machines list a full-power draw of 20 amps. Your electrician looks at the machine's amp draw, your panel and local code, then tells you what you need.
GFCI
6 ft
The 2023 National Electrical Code requires GFCI protection for every receptacle in a dwelling kitchen, plus receptacles within 6 feet of the top inside edge of a sink bowl anywhere in the home. A living-room bar next to a wet-bar sink counts. Towns adopt code editions on their own schedule, so ask which one applies to you.

Step 7
A direct water line means no more filling tanks, but it's a licensed-plumber job with real requirements.
Use a licensed plumber; follow local code and the machine maker's manual. That's the entire how-to from us. What follows is what the job involves, so you can decide if it's worth it and talk to your plumber like you did the homework.
| Question | Reservoir (tank) | Direct plumb |
|---|---|---|
| Water source | You fill a tank | Pressurized cold line under the counter |
| Water treatment | Pitcher, packets or in-tank filter | Inline filter or treatment system |
| Pump | Vibratory or rotary | Rotary, on machines built for it |
| Moving the machine | Easy | It stays put |
| Upfront cost | Lower | Plumb kit, filter, regulator, plumber, maybe a drain |
| Best for | Most home bars | Heavy daily use and Platinum builds |
Vibratory pumps are almost always tank-fed. Plumb-in readiness is designed in at the factory; forcing a tank-only machine onto a line isn't a supported conversion.
Backflow is water running the wrong way, back toward your drinking water. A cross-connection is any link where that could happen. An air gap is open air between the end of a pipe and the rim of whatever it drains into, so dirty water can't get pulled back. Plumbing codes treat coffee brewers in food businesses as indirect waste that drains through an air gap or air break, and one code sets a 1-inch minimum drainage air gap. What applies at home depends on local code. Your plumber knows.
Not ready? Buy a machine with a switchable water supply and a rotary pump. Run it on the tank now, then add the maker's plumb-in kit when the remodel happens. Clive Coffee lists La Marzocco's Linea Mini plumb-in kit, for example, as a separate part.

Step 8
The grinder decides how evenly your coffee extracts, which is why it matters more than the machine.
Water pulls flavor from the surface of every particle. Even particles extract evenly. Uneven ones don't: fines over-extract and go bitter and drying, while big chunks barely give up their flavor. Your grinder controls that spread. Nothing downstream can undo it.
Blade grinders work like tiny blenders and leave a mix of dust and chunks. Burr grinders crush beans between two burrs at a set gap for a much tighter spread. Cheap burr grinders beat blades, but small burrs that wear fast, plastic parts and weak motors still hold them back. Espresso asks even more: one coffee school notes most grinders offer one or two usable espresso settings when you really need 10 to 20.
| Job | What to look for | Why |
|---|---|---|
| Pour-over and batch | Burr grinder with consistent medium settings | Even particles, even extraction |
| Espresso | Stepless or micro-step adjustment | Tiny grind moves change shot time |
| Both | A grinder that returns to settings reliably, or two grinders | Swapping between filter and espresso costs beans and time |
| Travel | Hand burr grinder | No outlet required |
Shopping across tiers? A good grinder outlasts a few machine upgrades, so this is the place to stretch.
If the budget only stretches so far, put it in the grinder, not the machine. A great grinder makes a middling brewer taste good. It never works the other way around.
Whatever you buy, learn its settings. Note the number that works for each coffee and each brew method, so switching back is one turn, not a bag of test shots.
Grind size sets how fast water pulls flavor out of the coffee: finer for short, pressurized brews, coarser for long soaks. Start here, then taste. Sour or thin means go a little finer. Bitter or harsh means go a little coarser.
Every grinder numbers its settings differently, so match the look, not the number. Whole bean ground right before you brew keeps the most flavor; when you order ground coffee from us, pick the grind that matches your brewer.
Freshness
3–21 days
Coffee releases CO₂ for its first several days, so it hits peak flavor about 3 to 21 days after its roasted-on date. Enjoy it within 90 days, before oxidation dulls it. Keep whole beans in an airtight, opaque container at room temperature, and grind right before you brew. That last line is the whole reason a grinder lives on your bar.

Step 9
Every tier makes great coffee; more money buys speed, temperature control, milk power and convenience.
Price tags climb fast here. So does what you get: steadier temperature, steaming while you brew, a quieter pump, a water line instead of a tank. None of it matters if your grinder and water are off. Get those right, then pick your level.
| Tier | Rough budget | What it buys you | Typical gear |
|---|---|---|---|
| Bronze | ~$150–250 | Great black coffee, full control, no circuit questions | AeroPress, pour-over dripper, gooseneck kettle, hand grinder |
| Silver | ~$350–600 | A pot on autopilot, or a first espresso setup | SCA-certified batch brewer, or an entry single-boiler or thermoblock espresso machine |
| Gold | ~$900–2,500 | Stable temperature and real milk steaming | Prosumer single boiler with PID, a heat exchanger, or a dual thermoblock machine |
| Platinum | $2,500+ | Brew and steam at once, shot after shot; plumb-in optional | Dual boiler, often with a rotary pump and plumb-in kit |
Budgets are rough guides for a whole setup, and prices move. One buyer's guide puts single boilers at about $100–600, heat exchangers $1,000–2,500 and dual boilers $1,500–4,000 and up, before the grinder.
Bronze
~$150–250
An AeroPress or a pour-over dripper, a gooseneck kettle and a hand grinder make coffee as good as your beans, grind and water. No boiler, no plumbing, no panel math. It's also the best grind-and-recipe school there is, and every skill carries straight into espresso later.
Silver
90–96°C
Want a pot? Look for an SCA-certified home brewer. The current standard checks that the coffee bed reaches 90–96°C (194–205°F) early in the brew and stays there, and that the cup lands in the target strength range. Want espresso? Entry single-boiler and thermoblock machines pull real shots, but a single boiler can't brew and steam at once and typically takes 30–90 seconds to switch.
Gold
PID
A PID controller holds boiler temperature steady and can sit on any boiler type. Heat exchanger machines brew and steam at the same time with strong steam, but usually want a short cooling flush before a shot. E61 group heads, common above $1,000, circulate hot water for stability and need a long warm-up; one guide says 20–30 minutes for HX machines.
Platinum
$2,500+
Separate brew and steam boilers mean no temperature compromise and no cooling flush. Rotary pumps run far quieter than vibratory pumps and can take a direct water line. Machines like La Marzocco's Linea Micra and Linea Mini offer optional plumbing. This is where Steps 6 and 7 stop being optional reading.

Step 10
The cheap stuff does a lot of the work, and the scale does the most.
Consistency lives in the small tools. They also make the best wish-list items: they cost a fraction of a machine and fix real problems the day they arrive.
| Tool | What it does | Who needs it |
|---|---|---|
| Scale with timer | Weighs dose and yield and times the brew; look for 0.1 g readings | Everyone |
| Gooseneck kettle | Slow, aimed pours | Pour-over |
| Tamper | Compresses the puck flat and level; size it to your basket | Espresso |
| WDT tool | Thin needles stir out clumps before tamping | Espresso |
| Distribution tool | Levels the bed of grounds | Espresso, optional |
| Dosing cup or funnel | Catches grounds and keeps the counter clean | Espresso |
| Knock box | Holds spent pucks | Espresso |
| Milk pitcher | Steams and pours milk | Milk drinks |
| Cups and glasses | Sized to your drinks | Everyone |
Buy the scale first. Most of Step 11 is written in grams.
Recipes are written in grams. A common espresso start is 18 grams in and about 36 grams out, so a scale that can't see tenths of a gram can't tell 17.5 from 18.5. Our pour over recipe runs 22 grams of coffee to 400 grams of water. Eyeballing that is guessing. Weighing makes tomorrow's cup match today's.
WDT
5–10 sec
The Weiss Distribution Technique dates to 2005. Stir the dosed grounds with thin needles for about 5 to 10 seconds and lift straight out. It breaks up clumps that would otherwise leave low-density paths where water channels through, while the dense spots under-extract. Then tamp flat and level.

Step 11
Start with a recipe, change one thing at a time and let your taste make the call.
Dialing in means adjusting until the coffee tastes right. The rule: lock dose and yield, move the grind, taste, repeat. Write it down. Future you will thank present you.
| Method | Dose | Water or yield | Time | Notes |
|---|---|---|---|---|
| Espresso | 18 g | About 36 g out (1:2) | 25–30 sec from pump start | Lighter roasts often 1:2.5–1:3; darker roasts 1:1.5–1:1.8 |
| Pour-over (our recipe) | 22 g | 400 g water (Golden Cup, about 1:18) | 2–4 min total | Bloom with about twice the coffee's weight in water; medium grind |
| Batch brew (SCA Golden Cup) | 55 g | Per liter of water (about 1:18) | 4–8 min brew | Water 92–96°C (197–205°F) |
| AeroPress (our recipe) | 13 g | 240 g water (Golden Cup, about 1:18) | Stir 10 sec, press 20–30 sec | Fine grind; water 195–205°F |
Starting points, not laws. Taste wins.
Time is a guide, not a grade. If it tastes great at 32 seconds, it's great.
The SCA's Golden Cup standard aims for 18–22% extraction at a strength of 1.15–1.35% TDS, starting from about 55 grams of coffee per liter of water. Its newer home brewer standard widens the strength window to 1.15–1.55%. You don't need a refractometer to use either. Start at the ratio, then let your taste move you a little stronger or a little lighter.
Our roasts
Pour-over: Bloom, our light-medium. Batch brew for the house: Pathfinder or Ascender, both medium. Espresso: Apex, our house espresso, a dark roast, so start at the shorter end of the ratio range. Late cups: Navigator (decaf) or Midway (half-caf). Where we'd start Apex at home: 18 g in, about 32 g out, in 25 to 30 seconds. Dark roasts give up their flavor fast, so a slightly shorter shot keeps it sweet instead of ashy.

Step 12
Old coffee residue drags down flavor and minerals build scale, so a simple routine protects the cup and the machine.
Clean gear tastes better and lasts longer. This isn't a deep-clean weekend. It's a few minutes a day and a few more a month.
| Task | How often | Notes |
|---|---|---|
| Purge and wipe the steam wand | Every use | Wipe milk off before it bakes on |
| Water backflush | Daily to weekly | Only machines with a three-way solenoid valve |
| Detergent backflush | Every 2 weeks to monthly; E61 machines every 1–2 months | Guides disagree; your manual wins |
| Brush grinder chute and burr opening | Weekly | Stale grounds cause off-flavors and clumping |
| Grinder cleaning tablets | Monthly if you grind espresso daily | Package dose, then purge with sacrificial beans |
| Deep burr clean | Every 3–6 months | Brush only; don't wash burrs with water |
| Descale | Depends on your water | See below |
Non-backflush machines: soak the shower screen and baskets in espresso machine cleaner instead, roughly monthly.
Scale is minerals dropping out of hot water and crusting on boilers, valves and elements. Descaling removes it. Good water prevents it. One machine maker's rule of thumb by TDS: under about 30 ppm, scale essentially never forms; 30–120 ppm, descale about once a year; over 120 ppm, at least twice a year. La Marzocco warns against flow-through descaling on its machines. Use your manual's method, and treat heavy scale as a service job.
The step home baristas skip most: the steam wand. Wipe it and purge it for a second after every single drink, or milk dries inside the tip and you'll taste it in tomorrow's latte.
Put the weekly and monthly jobs on your calendar. A routine you don't have to remember is a routine that actually happens.
Backflushing
3-way valve
Only machines with a three-way solenoid valve can be backflushed: E61 machines, the Rancilio Silvia, the Linea Mini and most mid-range Breville models, like the Barista Express. The Breville Bambino line, manual levers and superautomatics don't have one. Some of them run their own cleaning cycle instead, so follow the manual, not a backflush routine. Listen for a hiss and a small dump of water after a shot. Your manual is the final word.

Under-sink reverse osmosis with a remineralization stage. Clean, consistent base water for a serious bar. Test what comes out before you brew: it's a base, not a coffee recipe.
About $15
Mineral packets for distilled or RO water, made to meet SCA water standards. We stock it; your pour-over will notice.
Step 13
A good cup at a campsite takes a hand grinder, a simple brewer, a way to heat water and a little planning.
Travel coffee doesn't have to be a downgrade. Same rules as home: good beans, good water, an even grind, a simple recipe. Just fewer outlets.
Brew with water you'd drink. Not sure? The CDC calls boiling the best way to kill germs: bring clear water to a rolling boil for 1 minute, or 3 minutes above 6,500 feet. Boiling won't remove chemicals, so start with water from a source you trust. You're heating water for coffee anyway, so boil it fully, then let it cool to brewing temperature. The AeroPress inventor's recipe calls for 80°C (175°F). Want mineral control on the road? A gallon of distilled water and a mineral packet travel fine.
Prep
Weigh each dose into its own small airtight container. Keep the beans whole until you brew. Pick a bag whose roasted-on date puts your trip inside the 3–21 day peak window. Our pick for the trip: Pathfinder for the AeroPress, since a medium roast forgives a rough grind and so-so water, or Embers if the crew wants a French press by the fire.
Bronze
$49.95
Packs a press, filters and a mug into one carry. A real cup at camp, in a hotel or at your desk.
About $35
Wide-mouth insulated mug that fits under most drippers. Brew straight into it and hit the road.
About $56
A ceramic-burr hand grinder for camp, work and travel. Also the cheapest way to grind fresh at home.
Platinum
$1,450.00
Acaia's first grinder. Weigh the beans in, grind them all, and it clears itself out between doses. Pair it with a Lunar and it grinds by weight.
Bronze
$149.95

Baratza's starter burr grinder for drip, pour-over, siphon and cold brew. Not an espresso grinder: for espresso, look at the OutIn Fino or a Mahlkönig.
About $400
64 mm flat burrs for clean, clear pour-over and batch brew. Not for espresso, and it doesn't pretend to be.
Straight answers
The stuff people search before they buy the machine.
A burr grinder, a brewer or espresso machine, a scale, a kettle for hand brewing and water that tests in range. Put it where there's counter space, a reachable outlet and a sink nearby. Espresso adds a tamper, knock box and milk pitcher.
One buyer's guide puts single-boiler machines at about $100–600, heat exchangers at $1,000–2,500 and dual boilers at $1,500–4,000 and up. Then add an espresso grinder, small tools and water treatment.
Water near the SCA targets: about 150 mg/L TDS, alkalinity near 40 mg/L, pH around 7, no chlorine. Your machine maker's spec comes first. Filtered tap water that tests in range works, and so does distilled or RO water with minerals added back. Skip raw distilled, raw RO and sodium-softened water.
Straight RO water, yes. It removes most minerals, so coffee extracts poorly and tastes flat, and very pure water can be aggressive toward machine metals. RO plus remineralization is a different story: it gives you precise control, and La Marzocco's Australian support page recommends RO for best machine performance.
Not on its own. Distilled water lacks the minerals that support extraction and can be hard on machines. Add a mineral packet built for espresso machines. Third Wave Water's directions are one packet per gallon of distilled water, and its Espresso Profile has no chlorides.
Be careful. Ion-exchange softeners swap hardness for sodium, and guides warn espresso can taste flat or slightly salty as a result. The SCA sodium target is around 10 mg/L. House on a softener? Ask a plumber about an unsoftened cold line for the bar.
No. Most home machines run from a tank. Plumbing in needs a machine designed for it, usually with a rotary pump and a switchable supply, plus a shutoff valve, pressure regulator, espresso-rated filter and backflow protection. Use a licensed plumber; follow local code and the machine maker's manual.
Often it's smart, and sometimes it's required. Many home machines draw 1,600–1,700 watts, most of a 15-amp, 120-volt circuit's 1,800 watts. La Marzocco's install guide for the original Linea Mini lists a 20-amp full-load draw. Check with a licensed electrician and local code, and bring your machine's spec sheet.
Under the 2023 National Electrical Code, every receptacle in a dwelling kitchen needs GFCI protection, and so do receptacles within 6 feet of a sink bowl elsewhere in the home. Local adoption of code editions varies, so confirm with a licensed electrician.
Use hardness test strips, which read in ppm or grains per gallon, and a TDS meter for total dissolved solids. Your utility's annual Consumer Confidence Report, due to customers by July 1, lists more. On a private well, test it yourself. Retest after any filter change.
The grinder. Even grounds extract evenly; uneven grounds mix bitter, over-extracted fines with under-extracted chunks. Coffee educators argue a great grinder can carry a cheaper machine, but not the other way around.
Try 18 grams in, about 36 grams out (1:2), in 25–30 seconds from pump start. Lighter roasts often taste better longer, around 1:2.5–1:3; darker roasts shorter, around 1:1.5–1:1.8. Fast and sour: grind finer. Slow and bitter: grind coarser.
We brew to the SCA Golden Cup ratio: 55 grams of coffee per liter of water, about 1:18. Our pour over is 22 grams of coffee to 400 grams of water, and a 6 ounce cup takes about 10 grams. Like it stronger? Add a gram or two of coffee next time.
Only if it has a three-way solenoid valve. Guides suggest a water backflush daily to weekly and a detergent backflush every two weeks to monthly, with E61 machines every one to two months. Your manual wins.
It depends on your water. One machine maker's rule of thumb: under about 30 ppm TDS, scale essentially never forms; 30–120 ppm, about once a year; over 120 ppm, at least twice a year. Follow your manual's method; La Marzocco warns against flow-through descaling.
Coffee releases CO₂ for its first several days, so it hits its peak about 3 to 21 days after the roasted-on date. Enjoy it within 90 days. Store whole beans in an airtight, opaque container at room temperature and grind right before you brew.
A hand burr grinder, an AeroPress or similar brewer, a kettle and heat source, a pocket scale or pre-weighed doses, a mug, safe water and a bag for spent grounds. Questionable water? The CDC says a rolling boil for 1 minute, 3 above 6,500 feet.
Glossary
Build it once. Build it right.
Water first. Grinder next. Then the brewer or machine that fits your mornings, the small tools that make it repeatable and the routine that keeps it running. Start your wish list with whatever fixes your biggest problem today, and add the rest as you earn it. Got a question your manual won't answer? Bring it to our roastery storefront. Bring your grinder setting, your water numbers or the shot that's been tasting off, and we'll help you work it out.
A home bar comes with a few house rules, “Reward the Grind” chief among them. Not for everyone. Probably for you.
