I recently brewed a Belgian Wit extract kit. Bottle conditioned with 5 oz of priming sugar. I'm pretty happy with the taste. With a medium speed pour into a Pilsner glass, the beer develops a rather thick, probably three fingers tall head. It slowly fades but a small head remains throughout. Good lacing continues as well. I can see a lot of continuous streams from random nucleation sites in the glass. It looks beautiful IMHO.
The problem is that it doesn't taste very carbonated. Some go as far to say that it tastes flat.
Any ideas why it develops a great head but still tastes flat? Thanks!
