The 30-Day Brew Challenge

Thirty days, one micro-skill a day, each one ten minutes or less. Do the day's task, tap it done, and watch the streak build. Your progress saves in your browser, nothing leaves your device, and day 30 ends with a certificate you can print. By the end you will have touched every skill that separates people who own coffee gear from people who use it well.

Your progress

0 of 30 days done

Tap a day to mark it done, tap again to undo. Days do not need to be consecutive; life happens.

The gear the challenge leans on

Nothing here needs new equipment, but four free tools carry the month: the brew ratio card (days 4 and 20), the dial-in logbook (day 14 and every day you feel like winning), the dial-in cheat sheet (day 19), the descale schedule generator (day 21), plus the coffee cost calculator (day 26) and the Home Barista Exam for graduation day.

Want the paper version? The 30-Day Coffee Journal ($9) is the printed twin of this challenge, one page per day, and Dial In in 7 Days ($9) is the espresso fast lane. Both are in the Barista Life shop preview.

Progress lives in your browser's localStorage and never leaves your device. Clearing browser data clears the challenge. The certificate is self-tracked and worth exactly as much as your honesty, which is the point. This page is technique practice, not health advice; how much coffee you drink while practicing is your business.
