Piles of large, white sack-cloth bags rest in the right corner of the room. Theyâre filled with green coffee beans â waiting for their moment to be poured into the roaster. The white cement walls are mostly bare, aside from a few posters. One is a taste-wheel diagram that David Frazier and Jose Thompson â the owners of Chestnut Ridge Coffee Roasters, a specialty coffee roaster in downtown Harrisonburg â use while doing coffee tastings to help them write descriptions of the flavor notes for each brew. âItâs fun to taste coffees with [Jose] because he has a completely different palette than I have,â Frazier said.
