The 3-Step Methodology

From bag to cup, zero guesswork

Great coffee isn't luck. It's the systematic adjustment of 5 key variables until the flavor in the cup matches the roaster's vision.

01

Log the Variables

Pick your brew method, dial in your coffee dose (grams), water weight, grinder click setting, and exact kettle temperature in seconds.

02

Rate & Tag Flavors

Score the cup from 1–10. Select SCA-calibrated tasting tags (acidity, sweetness, floral, cocoa) and note astringency or hollow finish.

03

Dial-In & Perfect

Brewlog correlates your ratings with brew variables. You'll see immediately: "Grind 1 click finer" or "Drop temp 2°C to tame bitterness".

Engineered For Taste

Everything you need to master extraction

Whether you brew delicate washed Geishas on a V60 or dense honey-processed espresso, Brewlog equips you with barista-grade tools.

Universal Recipe Vault

Dedicated parameters for V60, Espresso, AeroPress, Chemex, Kalita Wave, French Press, and Cold Brew. Never mix up pour-over ratios with 1:2 espresso extractions.

Bean Stash & Freshness Radar PRO

Track roast dates, remaining bag weight in grams, freezer vaults, and optimal degassing windows. Get alerted when your Gesha hits its 14-day flavor peak.

Grinder Calibration Sync PRO

Translate grind settings between 40+ popular grinders: Comandante C40 clicks, Fellow Ode Gen 2, Baratza Encore, Niche Zero, and 1Zpresso K-Ultra with zero math.

Multi-Stage Pour Timer

Follow step-by-step pulse pours. The timer guides your bloom, pour 1, and drawdown with visual targets so you hit your exact water weight every 30 seconds.

Extraction Yield Analytics PRO

Calculates estimated TDS and Extraction Yield percentage based on your refractometer readings or dose-to-yield equations. See sweet spot correlations in color.

Complete Data Ownership

Export your entire coffee journal to CSV or JSON anytime. Works offline in your kitchen without a cellular or Wi-Fi connection, syncing automatically when reconnected.

Frequently Asked Questions

Got questions? We have answers.

Everything you need to know about Brewlog, grinder compatibility, and how your coffee data is safeguarded.

Yes, 100%. Brewlog is designed as a local-first Progressive Web App. All your brew logs, recipes, and timer calculations function completely offline while you make coffee. When your device reconnects to Wi-Fi or cellular, changes sync seamlessly to the cloud.
Brewlog includes an extensive laboratory-measured particle distribution curve database for over 40 grinders (including Comandante C40, Fellow Ode 2, Timemore Chestnut, 1Zpresso, Baratza Encore/Sette, Niche Zero, and Eureka Mignon). You can switch recipes written for Comandante clicks directly into settings for your Fellow Ode or hand grinder with one tap.
Notes apps don't calculate real-time extraction yields, won't guide your pulse pours with an integrated timer, and won't correlate your flavor notes against grind clicks. Brewlog understands coffee physics: it actively identifies why a cup tasted acidic or bitter and tells you the exact adjustment to make on your next brew.
Absolutely. We believe your coffee journey belongs to you. Pro subscribers can export their entire recipe database, tasting notes, bean stash records, and sensory charts into clean CSV and JSON files at any moment with a single click.
When you select the Pro plan on signup, you get full unrestricted access to bean tracking, extraction analytics, and unlimited recipes for 14 days without charge. If you decide not to continue, you can cancel in one click or automatically downgrade to the Free plan while preserving your first 15 recipes.
