This convenient book has 3.5" x 5" dimensions. With these pocket sized journals, you can document the flavor profile of your favorite coffees, or new coffees. By documenting the flavor profile, you can evaluate the difference between roasters, processing techniques, origins, and changes that occur with the same farm from harvest to harvest. The unique flavor wheel in the 33 Cups of Coffee book can be used to quickly recall a coffee's unique flavor long after consumption.
