Yikes.
I love the idea, and am aware of the tradition of the use of birch sap and buds. But I happen to be allergic. On the typical skin test, out of a possible 4, I was a 4++++... they really didn't have a way to quantify how allergic I was. The area of the test site swelled up like a tennis ball for three days. I have itch reactions in the mouth and down the throat to any food related to birch, and members of the
rose family. But environmental exposure hasn't resulted in anaphylaxis yet, so I'm hopeful I won't have to move out of its growing range.
Still, I don't think I will be enjoying birch internally. I don't even know if it's safe for me to take chagga, and that just grows on birch.
But I may soon have the opportunity to tap some maples seasonally, though, and maple beer or maple jack sounds potentially delightful.
Good luck, and keep us posted.
