Every supporter who donates to our educational work will receive the e-book edition of The Roasting Bible, written by Wing HW Yuen (available on Amazon).

The author co-founded Tasse Coffee Lab in Hong Kong and Tasse Coffee Roastery in Tokyo, and for years has moved between the two — earning his SCA and CQI Q Instructor credentials along the way, and sitting as a competition judge. The Roasting Bible is the quiet distillation of that craft, set down on the page. To be able to place this labour of love in your hands is our privilege.
