Scan any specialty coffee bag. The AI reads origin, roast, and process — then builds a complete recipe made for THAT bean and YOUR equipment. Every coffee is different. A washed Ethiopian needs different parameters than a natural Brazilian. CoffeeMaster knows the difference and adjusts the recipe automatically. HOW IT WORKS 1. Snap a photo of any coffee bag 2. AI extracts origin, altitude, process, roast level, and tasting notes 3. Pick your method and grinder 4. Get a complete recipe: dose, water, temperature, timing, and exact grind setting BEAN-SPECIFIC RECIPES Not a generic "V60 recipe." Each recipe is calculated from the actual characteristics of your coffee. The same V60, different bean, different recipe. YOUR GRINDER. YOUR CLICKS. Stop Googling "medium-fine." CoffeeMaster knows 20+ grinders from Comandante, 1Zpresso, Timemore, Kinu, KINGrinder, and Hario — and calculates the exact click setting for every coffee. 6 BREWING METHODS V60 · Chemex · AeroPress · French Press · Espresso · Moka Pot. Configure size and variants to match your setup. YOUR COFFEE LIBRARY Every coffee you scan, every recipe you generate — saved. Track freshness, mark favorites, and re-brew any coffee with the same recipe. BREW LOG Rate each brew. Add notes. Track what works and what to adjust next time.
