As to the second: daily, more or less.
Personally I prefer a good dark roast, and if it’s a good blend (also for medium or light roast) I want it black.
Outside of dedicated coffeehouses though, most coffee out & about isn’t what I consider “good” (I guess I’m a snob?:-P), so I usually add sugar & creamer.
(Pro-Tip: combine black coffee with a pastry for the ultimate snack, i.e. the sugar doesn’t need to be poured directly into the liquid! The juxtaposition of the bitter and sweet really works well.:-)
I can’t stand Starbucks coffee regardless though, so if needed I’ll get a mocha. I’d sooner trust a McDonald’s coffee though - seriously: b/c Lavazza is great!
It’s such a personal choice though - what do you like?
It’s hard to beat the freshest coffee - though I wonder how climate change is going to impact that, and it’s always been difficult to attain “consistency” in single-origin material.
