You dont need a recipe if you have a hydrometer and can test the acid levels. Persimons dont have much acid so you can use a lot, they do have pectin so you need pectinase. Take all your ripe persimmons, smash them up, add just enough water to make a slurry, add pectinase and stir real good, let set overnight, strain pulp off, you are not going to get all of it,, add a little sulfite to protect it from oxidizing and add some nutrients, a wine yeast like Pasteur Champagne should do it very well. It will probably throw off a lot of sediment so if you want 5 gallons start with 7 gal of must. I wouldnt raise the gravity to much more than 1.095. Your choice of dry or sweet. I have planted 10 persimmon trees last year, hoping I have a go at this myself from my own trees! WVMJ
