Measure the grind
Photograph grounds on the free calibration mat to read particle distribution, D-values, fines, uniformity and brew-method fit. The original photo never leaves your device.
BREW VERO
Measure the grind.
Learn from every cup.
Brew Vero is a free coffee journal and grind-analysis system for home brewers, made by Barista in Pajamas. Measure a sample from a photo, record the recipe and taste of the cup, connect both in your private library, then use trends, Brew IQ, and practical guides to decide what to change next. Grind photos are analyzed on your device; sign in with Google only when you want your analyses, brews, coffees, and equipment saved across devices.

ONE CONNECTED COFFEE SYSTEM
From a handful of grounds to a better next brew.
Brew Vero connects what your grinder produced, how you brewed it, and how the cup tasted. Instead of isolated numbers and notes, every brew becomes useful context for the one that follows.
Record the brew
Save the coffee, grinder setting, dose, yield, time, temperature, rating and tasting notes. Link the actual grind report when you have one.
Understand the result
Use trends, the SCA brewing control chart and Brew IQ to compare your better cups, separate recipe issues from grind issues, and choose one useful next experiment.
Learn the why
Evidence-aware guides connect the data to grinders, beans, water, extraction and technique—so adjustments make sense instead of becoming guesswork.

Built to growRecipes and future coffee tools can join the same system.
No account is required to analyze a grind. Google sign-in is only for saving and syncing your private history. Brew Vero requests your name, email address and profile picture—never access to your email or permission to post. Read the Privacy Policy and Terms of Service.
BREW JOURNAL
Every cup, tracked
Dose, ratio, rating, tasting notes: log the cup and watch a real SCA brewing control chart, rating trends, streaks, and your top coffees build up the more you brew.
GRIND LAB
Measure the grind
Print the calibration mat, sprinkle grounds, shoot from above. You get D10/D50/D90, span, fines, a brew-method match and a flavor projection, measured on this device. Save any reading to your library.
Self-calibratingThe printed 100 mm square is the ruler: any phone, any angle.
Lab-style reportD10/D50/D90, span, fines, distribution & cumulative curves.
Brew & flavor matchMethod fit rings and a flavor projection radar, labeled as projections.
Brew journal & analyticsLog dose, ratio, rating and taste, then watch trends, streaks, and your brewing control chart build up.
How it worksfour steps
01Print the matAt 100% scale: verify with the ruler or a bank card on the printed page.
02Sprinkle & shootThin layer inside the square, tap to break clumps, shoot straight from above.
03Read the reportD-values, brew match, flavor projection: the grind side of the picture.
04Log the brewDose, ratio, rating, tasting notes: the cup side of the picture, saved to your journal.
Flavor and brew projections are heuristics from the size distribution alone. Detection floor ≈ 100 µm. Method adapted from Jonathan Gagné's open-source coffeegrindsize (MIT). Grind analysis is free without an account; saving a report and the brew journal both need one.

Before you shoot
Check the print scaleThe 100 mm square is the ruler. Measure it on paper before you trust any number.
Spread them thinGrounds should not touch. Tap the mat to break clumps, or two beans read as one.
Focus beats lightSquare to the mat, tap to focus, hold still. Soft photos get flagged or rejected.
Shoot threeThree photos of the same mat give a median reading and a spread you can trust.
