It makes for a more acidic brew, which I personally really like. It’s quite fruity as well, while still definitely being coffee.
Based on your recommendations, it might not be your cup of tea (or in this case, coffee!), but it might be worth a try if you want to expand your horizons. I am personally not into dark roasts, being mostly a medium to light-roast person.
Fetterman took a bit of a dark turn unfortunately, which I suspect is why he is where he is.
