Well, i'm curios if anyone here also tried to brew a walnut wine. I've got a couple of bottles from my spouse's grandma, and this year i've tried to make it myself. Had a couple of questions though. What's the time for taking the shells off. And when it will have its сhestnut's colour?
The article linked here suggests getting very young walnuts before you have to shell them; and instead quartering the young walnuts. They also suggest here leaving it 40 days, 52 days or 3 months; so, leaving at least 40 days seems to be a cunning plan.
I hope this helps.
