I make very little fruit wine, but it seems to me that you did everything correctly. I know that anything with peach in it has a time clearing so maybe you need to help it at this time. I have not tried it, but I have heard miraculous things about a product called "Sparkolloid." BTW, that is going to be some powerul wine!
Perhaps some of the fruit wine makers will chime in. Good luck.
Edit: Here is some information from Jack Keller's site:
[SIZE=+1]
Failure to Clear[/SIZE]: If you boiled ingredients to extract flavor, color or both and your wine fails to clear, you most likely have a pectin haze (see
Pectin Haze below). If your wine is made from starchy ingredients, especially grains or tubers, that were boiled and pressed through a nylon straining bag and then fails to clear, you most likely have a starch haze (see
Starch Haze below). If your wine has an off-color haze that fails to clear, you probably have a metal contamination (see
Colored Haze below). If you have a haze following a malo-lactic bacteria inoculation, you probably have a lactic acid bacteria haze (see
Lactic Acid Bacteria Haze below). If none of these apply and your wine fails to clear after six rackings at 30-day intervals, you simply have a nonspecific cloudy wine. Unless there is a bacterial contamination at work, the wine will probably clear but may take up to a year to do so. If you don't care to wait that long, there are several things you can do.
Move the wine into a cooler place for several weeks. All that is required is a drop in temperature of 10° F., but if the wine is over-heated in the first place (80° or more) you may have to bring the temperature down 20° or more.
If the above doesn't work, you might try using a fining agent. Most of these effect the taste of the wine somewhat, but I've found that mineral finings (Bentonite or Kaolin) effect it less than gelatin, egg whites or alkaline alginates. For a thorough discussion of fining agents, see
Finishing Your Wine.
The wine may fall clear if you add a clear wine of the same type to it. The exact amount to add is open to discussion, but most authorities say to add 25% of the volume of the cloudy wine, or one quart clear per gallon of cloudy wine. This doesn't always work, but it's worth trying before progressing to filtering.
Filtering definitely effects the taste and character of the wine and can ruin it if too fine a filter is used, but sometimes it is the only option left. Borrow, rent or buy a vacuum-pumped filter. They are fast, efficient and will clear almost any wine if the correct filter pad or paper is used. Gravity filters take a long time to work and expose the wine to the risk of oxidation. Just be forewarned before using a filter that doing so can change the wine and possibly ruin it.
