Your roast journal that actually works. Log every roast in under 30 seconds, track green bean inventory, and never forget what made your best roast great. No subscription — pay once, keep forever.
Chaff replaces your spreadsheet with a purpose-built journal for home coffee roasters. Whether you roast on a popcorn popper or a Behmor, Chaff makes logging faster than scribbling in a notebook.
LOG ROASTS IN SECONDS
Select your bean, enter charge weight, roast level, first crack, total time, drop temp — done. Development time ratio calculated automatically. Faster than any spreadsheet.
TRACK YOUR GREEN BEANS
Know exactly what you have left. Every roast auto-decrements your inventory. See which beans are running low before your next order.
SPOT WHAT WORKS
Quick stats show your total roasts, favourite bean, average development time, and weight roasted. Filter roast history by bean to compare results over time.
CUPPING NOTES LINKED TO ROASTS
Score each roast 1-5, tag aroma and flavour descriptors, link tasting notes directly to the roast that produced them. Answer "which roast was best?" without guessing.
BUILT FOR HOME ROASTERS
• Popcorn poppers, Behmor, Huky, air roasters, drum roasters
• First crack, development time, drop temp — the metrics that matter
• Works offline — no wifi needed
• Dark mode native — easy on the eyes
SIMPLE PRICING
Free with full roast logging, bean inventory, and roast history. Chaff Pro unlocks cupping notes, roast comparison, profile templates, and CSV export — one payment, no subscription, yours forever.
Your roasts deserve better than a spreadsheet. Download Chaff and start logging today.
