A delicious but unfortunately commercially-extremely-difficult-to-get beverage. It seems the only way to buy spruce beer in the United States is to spend a few days in Canada and then try to bring it back with you over the border. The Customs police may confiscate your spruce beer if they feel it's a proprietary product that violates trade rules, or they may think it's an explosive! Spruce beer has a cooling, refreshing piney and citrusy taste all at once. It's possible to make your own spruce beer, but black spruce only growns in the northernmost states in the US.
I once tasted Canadian spruce beer. Mouth-o!
