One coffee. Four ferments. One question answered.

Good Cup joins James Hoffmann, Square Mile, and Caravela for The Fermentation Project — a single Guatemalan coffee, processed four different ways, roasted to one identical profile. Fermentation is the only variable.

In the box:

• Four 100 g pouches, one per process
• A fermentation primer
• Four colour-coded tasting cards
• A grind size guide
• An invitation to the November livestream with James
