A step-by-step walkthrough of the Brewing Expert module. From choosing a method to troubleshooting your cup, here is everything the module offers.
From the main menu, tap Brewing Expert. This module is free forever — no purchase required. It's your go-to reference for dialing in every cup, whether you're learning pour-over or perfecting espresso extraction.
Select from 7 supported methods: Pour Over, Espresso, French Press, AeroPress, Cold Brew, Moka Pot, and Drip. Each method has its own dedicated guide with optimized parameters.
Each guide shows the essential parameters at a glance: brew ratio (coffee to water), grind size, water temperature, and brew time. For example, Pour Over uses a 1:15-1:17 ratio, medium-fine grind, 200-205°F (93-96°C) water, and a 2:30-4:00 brew time.
Below the parameters, find step-by-step brewing instructions specific to each method. The guides cover preparation, blooming, pouring technique, timing, and finishing — everything you need to brew consistently.
Not sure which grinder works best? The Brewing Expert includes grinder recommendations matched to each brew method, with grind size references from extra coarse (Cold Brew) through very fine (Espresso).
Learn when your coffee is at peak freshness. Green beans last months; roasted coffee peaks at 3-14 days post-roast. The freshness timeline helps you plan your roasting and brewing schedule for optimal flavor.
Green (unroasted) beans store for months in cool, dry conditions. Once roasted, peak flavor begins after a 2-3 day rest period and lasts through day 14.
If something tastes off, the troubleshooting guide helps diagnose the issue. Sour? Under-extracted — try finer grind or longer brew time. Bitter? Over-extracted — try coarser grind or shorter time. Each correction is specific and actionable.
The Brewing Expert module is included free with every RoastSource account. Open the app and start brewing better coffee today.
