When I looked it up on the internet people were tapping them, I think they said it's not as sweet. But they were saying it was good. Definitely better than the high fructose corn syrup my wife and kids like lol.
Huh... I didn't know that, but since we have so many Sugar Maples here it's no wonder nobody here taps anything else.
And no, I have never heard of Birch beer, if I see it sometime I will try it though
The most common variety around here.
