I know this is an old thread, just want to throw in my experience.
I make my grandfather's peach wine and the recipe is very similar. Except for the amount of peaches. Try scaling it back to a quart of ripe peaches halved(about 3-4 lbs). The flavor is very peachy. Not sure it could get more peachy honestly. Its easier for the pectic enzymes to break down fewer peaches rendering as much flavor as 20 lbs. Benefit is much quicker clarifying time without the extra remnants.
I wash, halve and pit the peaches, then squeeze them in my hand to break them up a little and throw in a bag. After primary fermentation I remove the bags allowing them to drain(don't squeeze) for a few minutes then rack for secondary. After all secondary fermentation is done I allow it to sit 2 more weeks to settle then bottle. It's 99% clear usually at that point.
Technically both of our recipes are just a sugar wash wine (Kilju) with fruit added for flavor.
Rack on!
