I have already pulped them and removed the stones. I am now left with 13 kg of plum pulp. And I thought mashing apples and pears was al lot of work! Plums beat those hand down!
If I would have enough plums, I would do a plum-only ferment, but since I only have 13 kg, I need to do some trickery, since my stlll has a minimum load of 4 liters (otherwise the element is above the fluid level). My other complication is that I have to keep the mash thin enough to avoid scorching.
I have looked up the sugar content of plums, which varies between 7,5 and 13,8 gram / 100 gram of fruit, so for my calculations I will use 10 gram / 100 gram or 10%. So I have 1,3 kg of sugar from my plums.
So I basically I think I have 3 options:
- Add water to get 10 liters of 7% potential mash and distill only once (slowly).
- Add water to get 10 liters of 7% potential mash, do a stripping run. Then wait till I get more plums, ferment again, then do a spirit run on the low wine and the fresh ferment.
- Add water and sugar to get 25 liters of 10% potential mash and distill twice (low wine would be about 7,5 liters, enough to fill my boiler).
Does anyone have any thoughts on that?
