Query: I tried and tried, but I still have no taste!

Nearly three heapin' tablespoons of freshly ground dark roast per cup couldn't bulk up the weak brew from my Starbucks Barista Utopia, made by Bodum for the coffee chain, which isn't restocking the electric vacuum pots. Starbucks' warranty services department reports that a thinner cup of coffee is correct and its enjoyment a matter of preference. (I was expecting a French press-like strength sans sediment.) I stressed that I really, really wanted this coffeemaker to work-and was hoping it was an early manufacturing kink that had since been ironed out-but was told to return it. I will, but I won't give up: Has the brewing time been lengthened with the newerfangled Bodum 3000 Electric Santos?
