I know it’s not going to be strong. However, having tasted birch sap before I’ve got a feeling there will still be a distinct taste there after the sugars have been fermented, and that’s why I wanted to try this. I have a forest industry book about all the things in trees apart from fiber and lignin, and from there I know that the sap has got all kinds of interesting constituents, so this could turn out to be a health cava :D Concentrating the sap would surely boost the taste, but that’s not in my interest for this experiment.

Great idea, thanks!

Very nice looking brew! Congratulations and welcome to the slippery slope XD
