When you buy Vietnamese coffee and burn it beyond all recognition into a cinder, it tastes just like the best coffee burnt into a cinder. When you add enough sugar, flavoring, and whipped cream, you can make cinder water taste good enough to have stupid people buy it.
And that is how Starbucks winds up on every street corner, making money.
Starbuck’s coffee is designed to be mixed with tons of cream, sugar, and other flavoring. If it wasn’t strong you wouldn’t be able to taste the coffee at all.
It’s terrible as a black coffee (which is how I drink coffee).
