I had a bottle with dinner the other night. It was served in the Sam Adams gimmicky glass and had almost no taste at all. In fact, the first few sips had less taste than water. Some taste after the first few sips, but nothing that stood out, no malts, no hops. Sam Adams' web site describes it as "the perfect transition from winters heavier brews to the lighter beers of summer." I call BS. If it tasted any lighter it wouldn't be beer.
Full disclosure: I rarely drink Sam Adams, but I have nothing against it. It's just that I live in Beervana, so there is no need to buy Sam Adams with all of the local craft beer available. I also like big beers like imperial IPAs and stouts. I did not expect Alpine Spring to taste like a big beer, but it would have been nice if it had a little more to offer.
