As an experiment, try Starbucks Kenya. It’s one of the most aggressively citrus-y among the coffees they serve — that sharp flavor even survives the darkish Starbucks “medium” roast.
Starbucks and Peet’s and Red Bay and Equator are all good for me. When I was in Europe I didn’t have a single bad espresso. Here I dislike many of them and stick to espressos from classic roast establishments. I wish it was easier to feed my occasional espresso kick.
