Don't they make the coffee to order at Starbucks? Never heard of Scooters.
I've had Starbucks (plain, my usual way) coffee twice, once in Chicago and once in NOLA, and both times it was the worst coffee ever, worse than any gas station, break room, or icky hotel "continental breakfast" pot. If people think that is what coffee should taste like, my taste buds feel sorry for their taste buds. No wonder they're adding sugar.
Frappuccino in a bottle is great, and definitely sweet, yummy!! But when they got ridiculously expensive, I quit buying them as an occasional substitute for making a coffee @ home.
They're brilliant though, making coffee into such a "thing" all of a sudden. I can remember coffee being 25ยข with free refills, most places.
