Portland, Maine roaster that bought a Honduras Cup of Excellence Gesha.
Will and Kathleen Pratt opened Tandem in Portland, Maine in 2012, after working in coffee in Boston, Martha's Vineyard, San Francisco and New York. A second shop, Tandem Coffee + Bakery, followed in 2014.
The roastery works with small growers and specialty importers. In October 2026 it bought a split share of Alma Pineda's washed Gesha, which placed eighth in the Exotic Varieties category at the 2026 Honduras Cup of Excellence, and in November it added two new Kenyan coffees, Oneska and Kibingo, from its partnership with Kamavindi Coffee Labs.
