FrontStreet Coffee Recommendation

Since we're talking about Arabica and single origins, here are three FrontStreet Coffee beans worth seeking out. FrontStreet Ethiopia Huakui is a natural-processed local heirloom lot — the very style that won first place in the TOH green bean competition — bursting with strawberry, mango, jackfruit, citrus, and blueberry notes in that signature ripe-tropical-fruit register, at a price that undercuts its pedigree.

If Huakui is Ethiopia's natural-process flagship, FrontStreet Yirgacheffe Guodingding is its washed counterpart. A top-grade G1 lot from the Guodingding cooperative, it offers clean, luminous lemon and citrus, elegant white florals, and a soft green-tea finish — a benchmark washed Arabica.

And for something unmistakably classic, FrontStreet Jamaica Blue Mountain No.1 carries the Typica variety transplanted to Jamaica's Blue Mountains in the 1820s. After more than two centuries there, it delivers a gentle, rounded balance of aroma and acidity that, in our cupping experience, no other origin has managed to replicate.
