So I managed to find 80% food grade alcohol (it was harder than you might thought) and started the all season maceration.
Basically every fruit that I will get or pick I just put few pieces there and let it sit, the tasting will be at Christmas or sometime in December. First layer is red currant, I already used it for some maceration so I know it starts good.
This is maceration not fermentation but I unintentionally did something similar with red currants and wine. I don't know how I made it but it was partly fermented with sugar wine and vodka (or some other clear distillate) to add more alcohol to be stable.
Found bottle few weeks ago and it was amazing, I forgot about it after I tasted it and don't liked it few years ago.
I don't like distillates that much, bit too strong for me, but basically fruit+bit of sugar+time+still and you have some eastern Europe pálenka/slivovice (from plums) or other "moonshine".
A friend of the family from Hungary used to bring out home-made palinka in small 7Up bottles to sneak them past customs. He said they would drink a few shots before and after every meal. Said that was how Hungarians became the highest per-capita meat-eating country in Europe.
I just remember it burning all the way down. The recipe I mentioned was more of a sweet liqueur and with lower risk of near-fatal distillation mishaps.
Will have to look into maceration. Thanks for the tip!
