Brewing

Comprehensive guides for 8 brew methods with ratios, grind size, temperature, timing, freshness guidance, and grinder recommendations. Everything you need to extract the best from your roasted coffee.

From Roast to Cup

Brewing is where all your roasting work pays off — and where you discover that the same roast can taste completely different depending on how you extract it. Understanding extraction, dialing in grind size and water temperature for different methods, and figuring out why a pour over brings out bright acidity while a French press emphasizes body and sweetness — it all connects back to how you roast.

A light-roasted Ethiopian that sings as a V60 pour over might fall flat as espresso without adjusting your approach. A dark Brazilian blend built for espresso might be too intense in an AeroPress but perfect as cold brew. The Brewing module helps you close that loop between roasting decisions and what ends up in your cup.

Overview

The Brewing module is your complete reference for turning roasted coffee into a great cup. It covers 8 brewing methods in detail — from espresso to cold brew — with specific ratios, grind sizes, water temperatures, and timing for each. The Overview section covers universal principles that apply to all methods.

Beyond the method guides, the module includes a Freshness and Grinding section that explains optimal rest periods for different brew methods and how grind consistency affects extraction. The Grinder Guide helps you choose the right grinder for your preferred method.

1 Choosing a Brew Method

  1. Browse the Overview for a comparison grid of all 8 methods.
  2. Select a method to see its detailed guide with ratios, timing, and instructions.
  3. Follow the step-by-step instructions for your chosen method.
  4. Adjust based on taste — the guide provides troubleshooting tips for common issues.

Things to Consider

Start with one method and master it before branching out. Each method highlights different flavor characteristics and pairs best with different coffees. Pour over reveals bright clarity and is ideal for light-roasted single origins like Ethiopian or Kenyan where you want those floral and fruit-forward notes to shine. French press emphasizes body and sweetness, making it a great match for medium-roasted Sumatrans, Brazilians, or chocolatey blends. Cold brew extracts less acidity than hot methods, producing a naturally smooth, sweet concentrate that is perfect for hot weather sipping and works especially well with darker roasts or nutty, chocolatey profiles. Espresso concentrates and intensifies flavors, rewarding well-developed medium to medium-dark roasts with thick crema and complex sweetness. AeroPress is the most versatile — it can produce anything from espresso-style concentrate to clean filter coffee, and its portability makes it ideal for travel. Moka Pot delivers a strong, rich cup similar to espresso and pairs well with bold, dark-roasted blends. Drip coffee is the everyday workhorse — consistent, forgiving, and great for medium roasts that balance sweetness and body. Your preferred flavor profile and lifestyle should guide your method choice.

2 Brewing Espresso

  1. Start with a 1:2 ratio — 18g of coffee in, 36g of liquid out.
  2. Target a 25-30 second extraction time.
  3. If the shot runs too fast, adjust the grind finer. If too slow, go coarser.
  4. Tweak dose and yield to fine-tune the flavor balance.

Things to Consider

Espresso is the most sensitive brewing method — small changes in grind size, dose, or temperature have significant effects on the cup. Preheat the portafilter and cup for temperature stability. Fresh beans (7-21 days post-roast) are ideal for espresso, as they need time to degas but lose aromatics over time.

3 Brewing Pour Over

  1. Use a 1:16 ratio (e.g., 20g coffee to 320g water).
  2. Bloom the grounds with twice their weight in water for 30-45 seconds.
  3. Pour in slow, steady circles, keeping the water level consistent.
  4. Target a total brew time of 2:30-4:00 minutes.

Things to Consider

Pouring technique matters significantly — avoid pouring directly on the filter walls as this creates channels where water bypasses the coffee. Water temperature should be 195-205 degrees F (90-96 degrees C). Paper filters produce a clean, bright cup by absorbing oils.

4 Brewing French Press

  1. Use a coarse grind and 1:15 ratio.
  2. Add all water and steep for 4 minutes.
  3. Press the plunger slowly and evenly.
  4. Pour immediately into cups to stop the extraction.

Things to Consider

Do not press too hard — excessive force forces fine particles through the filter and creates a gritty cup. Decant fully after pressing, because leaving coffee in the French press continues the extraction and leads to bitterness. The metal filter passes oils through, producing a fuller body compared to paper-filtered methods.

5 Brewing Cold Brew

  1. Use a coarse grind and 1:8 ratio for concentrate.
  2. Steep for 12-24 hours in the refrigerator.
  3. Strain through a fine filter or cheesecloth.
  4. Dilute to taste and serve over ice.

Things to Consider

Longer steeping produces a stronger concentrate — experiment between 12 and 24 hours to find your preference. Cold water extracts less acidity than hot water, resulting in a naturally smooth, sweet cup. Cold brew concentrate keeps well in the refrigerator for 1-2 weeks.

6 Brewing AeroPress

  1. Use a medium-fine grind and 1:15 ratio.
  2. Choose standard or inverted method (inverted prevents early dripping).
  3. Steep for 1-2 minutes.
  4. Press for 20-30 seconds with steady pressure.

Things to Consider

The AeroPress is extremely versatile — you can experiment with water temperature, grind size, steep time, and pressure to produce everything from espresso-style concentrate to clean filter coffee. It is also one of the best travel brewing devices due to its compact size and durability.

7 Brewing Moka Pot

  1. Fill the bottom chamber with hot water up to the safety valve.
  2. Use a fine grind (but not as fine as espresso).
  3. Heat on low to medium heat.
  4. Remove from heat when the upper chamber is about 80% full.

Things to Consider

Overheating is the most common Moka Pot mistake — it produces a burned, bitter taste. Pre-heating the water before adding it to the bottom chamber reduces the time the coffee grounds are exposed to heat and minimizes metallic taste. Remove from heat before the sputtering phase begins.

8 Brewing Drip Coffee

  1. Use a medium grind and 1:17 ratio.
  2. Ensure your machine heats water to 195-205 degrees F (90-96 degrees C).
  3. Use a quality paper filter and rinse it before brewing.
  4. Clean your machine regularly — descale monthly.

Things to Consider

Water quality matters most in drip coffee because it is the largest ingredient by volume. Use filtered water. Many lower-cost drip machines do not reach the proper brewing temperature — an SCA-certified brewer guarantees correct temperature. Clean mineral scale deposits monthly for consistent performance.

9 Understanding Freshness

  1. Check the Freshness & Grinding guide in the Overview.
  2. Learn optimal rest periods: espresso 7-14 days post-roast, filter 3-10 days.
  3. Understand degassing — CO2 released after roasting affects extraction.
  4. Match grind timing to brew method — grind immediately before brewing for best results.

Things to Consider

Grinding immediately before brewing is the single biggest improvement most people can make. Whole beans stay fresh for 2-4 weeks post-roast in a sealed container. Espresso requires more rest time than filter methods because CO2 interferes with even extraction under pressure.

10 Using the Grinder Guide

  1. Open the Grinder Guide from the Overview section.
  2. Learn the differences between burr and blade grinders.
  3. Match grinder settings to your preferred brew method.
  4. Understand how grind consistency affects extraction quality.

Things to Consider

Burr grinders produce significantly more consistent particle size than blade grinders, which leads to more even extraction and better flavor. Manual burr grinders are an excellent affordable option — a $30-50 hand grinder can outperform a $100 electric blade grinder. Grind size is the primary variable for adjusting extraction.

11 Using Taste Calibration

  1. Read the Taste Calibration section after Universal Brewing Principles.
  2. Learn the signs of under-extraction: sour, thin, salty, tea-like, lacking sweetness.
  3. Learn the signs of over-extraction: bitter, astringent, dry, hollow.
  4. Learn what well-extracted tastes like: balanced sweetness, clean finish, pleasant acidity.
  5. Distinguish dark roast bitterness from over-extraction — they feel different in the cup.

Things to Consider

Dark roast bitterness is a character trait of the roast itself and feels heavy, smoky, and persistent. Over-extraction bitterness is sharp, astringent, and drying. Being able to tell them apart helps you know whether to adjust your brewing or your roasting. Each brew method also includes roast-level adjustment notes — lighter roasts benefit from hotter water and finer grinds, while darker roasts need cooler water and coarser grinds.

12 Troubleshooting Taste

  1. Bitter? Try a coarser grind or shorter brew time (over-extraction).
  2. Sour? Try a finer grind or longer brew time (under-extraction).
  3. Weak? Use more coffee or less water (increase ratio).
  4. Watery? Check grind consistency and water temperature.
  5. Use the Taste Calibration guide to confirm whether it’s an extraction issue or a roast-level characteristic.

Things to Consider

Change one variable at a time so you can identify what made the difference. Keep a brew log — even brief notes help you remember what worked. The most common issue for new brewers is using water that is not hot enough, which produces sour, under-extracted coffee.

13 Using Brew Calculators

  1. Tap the 🧮 Brew Calculators toggle at the top of the Brewing module.
  2. Pick your brew method (espresso, pour over, French press, etc.).
  3. See the computed ratio, grind, time, and dose for that method — adjust the coffee:water ratio with − / + and scale by number of cups.
  4. Switch back with 📋 Full View to return to the detailed method guides.

Things to Consider

Each method shows its ideal ratio plus a typical range, with a Stronger/Weaker hint if you push past it. Brew Calculators is live in the app today — it's the fastest way to get dialed numbers for any method without leaving the module.

Tips & Best Practices

  • Each brew method now includes roast-level adjustment notes — check these when switching between light and dark roasts.
  • The Taste Calibration section helps you distinguish dark-roast bitterness from over-extraction — knowing the difference saves wasted adjustments.
  • Bitter = over-extraction (grind coarser, brew shorter). Sour = under-extraction (grind finer, brew longer).
  • Water quality matters — use filtered water for the best results with any method.
