One of the many excellent coffee roasters in Portland, Coava occupies an industrial-chic space in the Central Eastside that’s more than a spot to duck in for an espresso. The airy 13,000-square-foot operation includes training facilities, an enormous coffee silo in which beans are stored, and, of course, a retail coffee bar from which visitors can watch much of the coffee-roasting process unfold. Though Coava’s beans are proudly served at some of Portland’s best coffee shops, many of the pour-overs at its “brew bar” are available in limited quantities and not served anywhere else.
