The brands that used to have a Birch Beer were usually the brands that had a cream soda and a root beer. Birch would slide right into that lineup. I have kept expecting IBC to make a Birch Beer so that I could at least try it. No luck. Stewarts....same story....should have one but don't. Jones or Dr Jones whatever the hell it is should probably not even attempt it.
Polar has one I THINK. I know they had one. Not to my liking but as with all things, your mileage may vary.
It is usually clear in color and that clear color makes you feel like you just got your hands on some real moonshine liquor though the taste is not similar.....but that clarity of the liquid just makes you feel like you are doing something illegal, especially if you are only 8 years old. Its moonshine clear as opposed to sparkling water clear.
