Will it work with my coffee and my setup?

If your bag shows origin, roast, and process, the scan reads it cleanly. That covers most specialty coffee from local roasters, subscription boxes, or direct-trade. Generic supermarket blends still work, the base recipe is less tailored. On gear: 30+ grinders across Comandante, 1Zpresso, Timemore, Kinu, KINGrinder, and Hario, manual and electric, stepped and stepless. Don't see yours? Tell us and we'll add it within a week.

What happens if the first brew isn't great?

The first recipe is right for most people, most of the time. Think of it as skipping 3-4 rounds of trial and error. If it's not quite dialed, log the brew with a rating and two taps of feedback. The next recipe adjusts. No card on file, nothing to cancel, nothing to lose.

How is this different from every other coffee app?

Other apps give you a V60 recipe. Coffee Master gives you this V60 recipe, for this coffee, on your Comandante C40 at click 23. A natural Ethiopian and a washed Colombian get two different recipes. Different temp, different grind, different pour. The adaptation is the product.

Wait, is this really AI deciding my coffee?

Yes. An AI model builds the base recipe. But it doesn't pull numbers out of thin air. It reads what's on your bag (origin, process, roast, freshness) and matches it to the grinder you own. The recipe is your starting point. The rest is up to you, like always.

When will my coffee taste better?

The next bag you brew. Scan takes under 10 seconds. The recipe is ready before your kettle hits temperature. Most people nail the cup on brew #1 or #2, and keep that recipe in their library for every re-purchase.

The first 3 scans are free, no card needed. After that, upgrading unlocks unlimited scans. Every coffee and recipe already in your library stays yours.

Can I adjust the recipe?

Yes. Log each brew with a rating and notes. Your feedback adjusts the base recipe for next time. You can also tweak any recipe by hand. The fine-tuning is yours.

Yes. Your coffee scans, recipes, and brew logs are yours. We don't sell your data. Everything is protected behind your account.

How many clicks on a Comandante C40 for V60?

For a V60, a Comandante C40 works well around 16-23 clicks, depending on the coffee. A good starting point is 20 clicks for a light roast, a couple of clicks coarser for darker roasts. Coffee Master calculates the exact setting based on the specific bean you scan. Origin, roast, and process all affect the ideal grind.

What grind size should I use for AeroPress?

AeroPress grind size depends on your recipe. For a standard 2-minute brew on a Comandante C40, 16-17 clicks works well. Inverted method with a longer steep? Go a touch finer (14-15 clicks). Every grinder has its own scale, so Coffee Master converts the recipe into the exact clicks for yours.

What's the difference between 'medium-fine' and exact grind clicks?

Terms like 'medium' mean different things on different grinders. A V60 grind on a Comandante C40 lands around 20-22 clicks depending on roast level. On a 1Zpresso JX-Pro the scale uses a Rotation.Number.Tick notation, a completely different reading for the same bean. Coffee Master translates every recipe into the exact setting for your specific grinder. No cross-referencing spreadsheets.

What brew methods does Coffee Master support?

Ten methods, including V60, AeroPress, Chemex, French Press, Espresso, and Moka Pot. Each base recipe includes water ratio, temperature, grind size in exact clicks for your grinder, and step-by-step timing. Every parameter shifts to match the coffee you scanned.

The coffee you waste dialing in

New bag.
Back to zero.

Every new bag starts from zero

You open a new $22 bag, pull out your recipe, and brew. It's off. You tweak grind, then temp, then ratio. Three or four brews in, it's finally dialed, and a third of the bag is gone before it tastes the way it should.

The recipe doesn't adapt to the bean

A natural Ethiopian wants lower heat and pulse pours. A washed Colombian wants more heat and a continuous spiral. But you've been pouring both at 93°C, same ratio, same technique. And then you blame the bag when it doesn't click.

"Medium-fine" is a shrug, not a setting

You Google "Comandante C40 medium-fine clicks" and find four different answers. Every bean means a new guess. Every guess means another brew wasted dialing it in.

You're not a bad brewer. You're starting from scratch every bag when you shouldn't have to. Here's the fix ↓

Field notes

What coffee people are brewing.

“Scanned my natural Yirgacheffe and the V60 recipe pulled out strawberry notes I'd never gotten before. First time I didn't tweak a thing.”

Alex R.Home brewer · V60 + Comandante C40First-try success, zero adjustments

“I used to brew every coffee at 93°C. Coffee Master dropped my natural to 88°C with pulse pours. Completely different cup. Now I trust the recipe more than my instinct.”
