Brew Guides

The Cup Is Only as Good as the Brew

We spend a lot of time thinking about sourcing and roasting — because the quality of the bean matters enormously. But even the best coffee in the world can be ruined by a bad brew. Water that is too hot. A grind that is too fine. A ratio that is off by enough to flatten everything that made the bean worth buying in the first place.

These guides exist because we want the coffee you buy from us to taste the way it was meant to taste. Not just good — the way it was dialed in before it shipped. That requires a little knowledge and a little attention. Neither takes long to develop.

Pick your brewing method below and start there. The rest will follow.

How to Brew the Perfect Cup: The Fundamentals

Before you get into method-specific details, there are four variables that apply to every brewing method. Get these right and you are most of the way there regardless of how you brew.

  • Start with fresh beans. Coffee is a perishable product. Whole beans stay fresh for 2 to 4 weeks after roast date when stored in an airtight container away from light and heat. Pre-ground coffee goes stale within hours. Grind immediately before brewing, every time.
  • Use filtered water. Coffee is approximately 98 percent water. If your water tastes off, your coffee will too. A simple pitcher filter makes a noticeable difference. Avoid distilled water — it lacks the minerals needed for proper extraction.
  • Control your temperature. The ideal brewing temperature for coffee is between 195 and 205 degrees F — just off a full boil. Boiling water (212 degrees F) scorches the grounds and pulls bitter compounds. Water that is too cool under-extracts and produces flat, sour coffee.
  • Measure your coffee and water. Eyeballing produces inconsistent results. A simple kitchen scale removes the guesswork and makes your results repeatable. Once you find a ratio you love, you can hit it every time.

Pour-Over

Best for: Light to medium roasts, washed process coffees, anyone who wants to taste the full clarity of a single-origin bean.

What you need: Pour-over dripper (Hario V60, Chemex, Kalita Wave, or similar), paper filter, gooseneck kettle, scale, timer, freshly ground coffee.

Grind size: Medium-fine — similar to table salt. Finer than drip, coarser than espresso.

Ratio: 1:15 to 1:17 (1g coffee per 15 to 17g water). Start at 1:16 and adjust to taste.

Water temperature: 200 to 205 degrees F.

Brew time: 3 to 4 minutes total.

Step by step:

  1. Rinse your paper filter with hot water to remove any papery taste and preheat the dripper. Discard the rinse water.
  2. Add your ground coffee to the filter. Give it a gentle shake to level the bed.
  3. Start your timer. Pour just enough water to saturate all the grounds — about 2 times the weight of the coffee. This is the bloom. Let it sit for 30 to 45 seconds. You will see the grounds bubble and expand as CO2 releases — a sign of fresh coffee.
  4. Continue pouring in slow, steady circles, keeping the water level consistent. Pour in 2 to 3 additional stages, allowing the water to draw down slightly between pours.
  5. Total brew time should be 3 to 4 minutes. If it is draining too fast (under 2:30), go finer on your grind. If it is draining too slow (over 4:30), go coarser.

Common fixes: Sour or weak — grind finer or use hotter water. Bitter or harsh — grind coarser or lower your water temperature slightly.

French Press

Best for: Medium to dark roasts, naturally processed coffees, anyone who wants a full-bodied, rich cup with no paper filter between them and the bean.

What you need: French press, burr grinder, kettle, scale, timer.

Grind size: Coarse — similar to coarse sea salt or raw sugar. This is the most important variable in French press brewing. Too fine and the cup will be gritty and over-extracted.

Ratio: 1:15 (1g coffee per 15g water). For a 32 oz press, use approximately 55g coffee to 825g water.

Water temperature: 200 degrees F — 30 seconds off a full boil.

Brew time: 4 minutes steep.

Step by step:

  1. Preheat your French press by rinsing it with hot water. Discard the rinse water.
  2. Add your coarsely ground coffee to the empty press.
  3. Start your timer. Pour just enough water to saturate all the grounds and let it bloom for 30 seconds.
  4. Pour the remaining water slowly and evenly. Give the grounds a gentle stir to ensure full saturation.
  5. Place the lid on with the plunger pulled all the way up. Do not press yet.
  6. Steep for 4 minutes exactly.
  7. Press slowly and steadily over 20 to 30 seconds. If the plunger is hard to push, your grind is too fine. If it falls freely, your grind is too coarse.
  8. Pour immediately. Do not let the coffee sit in the press — it will continue to extract and turn bitter.

Common fixes: Gritty or muddy — grind coarser or switch to a burr grinder. Bitter — shorten steep time or go coarser. Weak — increase your coffee dose or steep slightly longer.

Cold Brew

Best for: Medium to dark roasts, full-bodied coffees with natural sweetness and low acidity. Cold brew is smooth, sweet, and forgiving — and it keeps in the refrigerator for up to two weeks.

What you need: Large jar or cold brew pitcher, coarse grinder, fine mesh strainer or cheesecloth, refrigerator, patience.

Grind size: Extra coarse — coarser than French press. Think rough breadcrumbs.

Ratio: 1:8 for concentrate (1g coffee per 8g water), which you dilute 1:1 with water or milk before drinking. Or 1:15 for ready-to-drink cold brew.

Water temperature: Cold or room temperature filtered water. No heat involved.

Brew time: 12 to 24 hours in the refrigerator. 12 hours produces a lighter, brighter cold brew. 18 to 24 hours produces a richer, more concentrated result.

Step by step:

  1. Combine your extra-coarse ground coffee and cold filtered water in a large jar or pitcher. Stir gently to make sure all the grounds are saturated.
  2. Cover and place in the refrigerator.
  3. After 12 to 24 hours, strain through a fine mesh strainer lined with cheesecloth or a paper filter. This may take 10 to 15 minutes — do not rush it.
  4. Store the strained cold brew in a sealed container in the refrigerator for up to 2 weeks.
  5. If you brewed concentrate, dilute 1:1 before serving. Taste and adjust.

Common fixes: Too bitter — reduce steep time or go coarser on your grind. Too weak — increase steep time or use more coffee. Cloudy — strain through a paper filter for a cleaner result.

Drip Coffee Maker

Best for: Medium roasts, everyday brewing, households that want a consistent, low-effort cup without sacrificing quality.

What you need: Drip coffee maker, paper or reusable filter, burr grinder, filtered water.

Grind size: Medium — similar to coarse sand. Slightly coarser than pour-over, finer than French press.

Ratio: 1:15 to 1:17 (1g coffee per 15 to 17g water). For a standard 12-cup maker, use approximately 60 to 70g of coffee.

Water temperature: Most drip machines do not reach the ideal brewing temperature of 195 to 205 degrees F. If your machine has a bloom or pre-infusion setting, use it. If not, consider a machine with a SCAA-certified brewing temperature for best results.

Step by step:

  1. Use filtered water in your reservoir.
  2. Rinse your paper filter before adding coffee to remove any papery taste.
  3. Add freshly ground coffee at your target ratio.
  4. Brew immediately. Do not let ground coffee sit in the filter before brewing.
  5. Serve promptly. Coffee left on a warming plate continues to cook and will turn bitter within 20 to 30 minutes. Transfer to a thermal carafe if you are not drinking it right away.

Common fixes: Bitter or burnt — your machine may be running too hot, or the coffee is sitting on the warming plate too long. Weak or flat — increase your coffee dose or grind slightly finer.

Tips for Getting the Best Flavor

  • Buy fresh and buy whole bean. The single biggest upgrade most people can make. Fresh-roasted whole beans, ground immediately before brewing, produce a noticeably better cup than anything pre-ground.
  • Invest in a burr grinder. Blade grinders chop unevenly, producing a mix of fine powder and large chunks that extract at different rates. A burr grinder produces consistent particle size, which means consistent extraction and consistent flavor.
  • Store your coffee correctly. Airtight container, away from light, heat, and moisture. Not in the freezer — the condensation from repeated freeze-thaw cycles damages the bean. Room temperature is fine for up to 4 weeks.
  • Clean your equipment. Coffee oils go rancid and build up on grinders, carafes, and brewers. A clean brewer produces a cleaner cup. Rinse after every use and deep clean weekly.
  • Taste and adjust one variable at a time. If your coffee is not right, change one thing — grind size, ratio, or temperature — and brew again. Changing multiple variables at once makes it impossible to know what fixed it.
  • Pay attention. The best thing you can do for your coffee is slow down and actually taste it. Notice what is there. Notice what is missing. That attention, over time, is what turns a good cup into a great one.
