River Phin Coffee Roasters is a small-batch specialty roaster in Foster City and Oakland, California, founded by Certified Q Grader Vy Nguyễn. It hand-sources from small farmers in Asia and beyond, with coffees from Vietnam, Indonesia, Thailand and Colombia, and sells online and at the Foster City Farmers Market.
River Phin Coffee Roasters was founded by Vy Nguyễn, a Certified Coffee Q Grader, U.S. Roasters Championship judge and trained R-Robusta grader. Her focus on clean coffee comes from personal experience: growing up, she got sick from unclean coffee, and her mission since has been beans free of mold, fungus and chemical residue. Her roots are in Hanoi, Vietnam, where her grandfather was a tea producer who handcrafted his own tea. Vy trained under Willem Boot and has worked with roast masters in Vietnam on roasting Robusta and on slow brewing with a phin filter. She visits the small farmers she buys from, hand grades the beans, and roasts in small batches in Foster City and Oakland. Every bean goes through at least three rounds of defect sorting before it is packaged, and the coffee bags are 100% compostable. Q Graders Sharon Fung and Harold work with her as consultants.
