I just started my first batch of persimmon wine last Tuesday, and I think it's coming along nicely.
We have a hachiya persimmon tree where I live and we collected about 15 lbs off of it that were in easy reach. Hachiyas, of course, are ripe when super soft, and horribly astringent otherwise, so I let them ripen on the counter unitl I had about 6 lbs. You can freeze them as they ripen but I just let mine sit off to one side till I had enough. I put a couple of apples in the mix to help them ripen.
To process I cut off the calyx (the leafy part where the fruit attached to the tree) and squeezed the pulp into my primary bucket lined with a nylon mesh bag and then dropped the skin in there as well. I added pectic enzyme, 1.5 tsp of citric acid, a couple of crushed campden tablets, and enough water to to make 1.5 gallons. Then let this sit overnight.
The next day, I added 5 lbs of corn sugar boiled with enough water to hit 2.5 gallons. Well that was my plan anyway. I had trouble accounting for the volume of pulp in the mesh bag and ended up with close to 3 gallons (almost 3.5 with the bag in the water). The gravity tested at 1.080 anyway. I added yeast nutrient and pitched 3 grams of Epernay 2. Which was billed as good for non-grape wines and also low and slow. Boy is it ever, I can see bubbles when I peak under the lid but it's not enought to move the airlock. The Epernay supposedly developes a bouquet and has a tendency to get stuck, good for semi-dry wines.
Just took a sample today, still sweet at 1.068 with a mango, tropical fruit flavor. Added more nutirent and resolved to be patient.
