I do a peach wine every year, it is not terrible but it is not as easy as some other fruits.
Point to note: Peaches are very high in pectin be very liberal in the use of pectic enzyme.
I do a full fruit batch ~ 10lbs per gallon, I get 50 lbs and the farm I get them from also gives me 2-3 pounds of Niagara (Coronation sovereign grapes) I crush and add those to improve the color of the wine.
After destoning the peaches, sprinkle with pectic enzyme and freeze them (I freeze them for a week)
Thaw and mash them, it will be a pudding consistency add grapes.
Add a full dose of pectic enzyme stir and let sit covered overnight.
use a strainer to get enough juice to measure SG. Add sugar (as simple syrup or heavy syrup) to get SG to 1.080.
Add acid to get the pH to 3.2
Add yeast nutrient per package direction.
pitch yeast of your choice - I just use EC-1118 for it.
punch down twice per day.
Second does of nutrient around SG 1.020
Rack and press at ~ 1.010
After 1 week ( fermentation should be done) Rack and add kmeta
Clarify with keilsol and chitosan should clear within 2 weeks if not hit it with more pectic enzyme
Add potassium sorbate and sweeten to taste. - even if you want a dry wine you need to back sweeten a bit to bring out the peach flavors.
The wine is drinkable in about a month but much better after 6 or 7 month. I typically make it in September (peach harvest in Ontario, Canada) for drinking the next summer.
Most of this I learned from reading threads by
@Scooter68 hopefully he will chime in.
