Anyone tried Acorn based brews.

I do a lot of home brewing - mainly cider and wine. I also do some gathering. This year ive been processing acorns. As a trial ive been leaching intact acorns. Ive noticed the peeled whole acorns undego a fairly vigorous natural fermentation.

Im processing 1.5kg in a sealed mason jar of 3l capacity. The carbonation is very active. After a week the initial tannis load has reduced a lot and the water isnt really bitter anymore. However theres quite a bit of avive fermenting going on.

For pure curiosity i had a sip of the wash today and its like a mildly fizzy lite nutty cider. Anyone ever tried using the wash to make beer/ wine or similar from processing acorns?
