My Persimmon Wine Won't Clear!

Persimmon WineI have been making wine for over a year and lately have had no trouble clearing the wines. I started a 6 gallon batch of persimmon wine 1st Nov. According to our wine recipe it should be ready to bottle in the next week but it is still not clear. I have used several clearing agents. Will it clear if I just leave it for an extended period of time? I am going to rack it again. There is a lot of sediment in the bottom of the carboy. I have heard of people making persimmon wine so since I got the persimmons free I wanted to try it. Have you heard from anyone who has made persimmon wine.

Hello Sandra,
Thank you for the great question, and yes, I have heard of people making persimmon wine. I have never made it myself, but have partaken in it more than once.
There are a couple of things that could be going on with your wine. The first is that it may still be fermenting, only very slowly. It is not uncommon for a fermentation to drag on for extended periods of time when cooler weather comes upon us. Wine yeast are very sensitive to temperature. If your wine is in the 60’s, instead of the 70’s this could be your issue.
Fortunately, it is very easy to determine if temperature is the culprit. Simply take a hydrometer reading. If you are not getting a specific gravity reading of .998 or less, then the fermentation is not done. If you don’t have a gravity hydrometer, I would strongly urge you to get one. It is the most valuable tool you could have as a home winemaker.
If you discover that the temperature is the issue, the remedy is simple: warm the wine must up. You will see the fermentation become more active so that it can finish up and then clear up!
This second and more serious problem could be your wine has developed a pectin haze. Persimmons have a lot of pectin in them. Pectin is the gelatinous stuff that holds together the fruit fiber. It’s the stuff that allows you to make jellies and jams out of fruit. All good for toast but bad for making wine. If the pectin is not broken down during the fermentation your wine can develop a pectin haze.
This is why most wine recipes will call for pectic enzyme. This will help to break-down the pectin and eliminate the chance of a pectin haze. If you did not use pectic enzyme, or if the pectic enzyme you have is old, than this could definitely be your problem.
One way to test for this is to take a small sample of the wine and add teaspoon of pectic enzyme to it and let sit overnight. It the sample clears without causing any sediment, then a pectin haze is your problem. The only possible way to solve this problem would be with a double-dose of pectic enzyme and patience. Many times the wine will clear up with this treatment within a few weeks, but unfortunately, there are some wines that will never clear.
I hope this helps you out, Sandra,

  1. would filtring do the trick?i have a peach mead that hasnt cleared despite numerous clarification methods, ie:bentonite,extra pectic enzyme, and twice with chitosan…………….i think the next best thing is a filthr system

  2. Jim, there are two things I need to mention here: 1) filtration will have no effect on a pectin haze. It is not caused by particles, but rather the molecular make-up of the liquid and how it refracts light. 2) If the wine is visibly cloudy in the least from actual particles and not a pectin haze, a wine filter will clog up very quickly. Wine filters are designed to add polish to a wine the already looks clear. They are not designed to solve a cloudy problem.

  3. I made a persimmon wine this year and the fermentation seemed to take a very long time. Once the bubbling stopped, it cleared very nicely. However, I have a pear wine that I also started this fall that is not clearing. I suspect it may be pectin haze. I added pectic enzyme to the must, but maybe it was not enough. I am going to test it as you described above and try treating it with pectic enzyme.

  4. I also started a Persimmon wine on Dec. 5, 2012. using a seedless variety. Using an enzyme extraction method on 30 lbs. of fruit (chopped to 1/8’s, 6 tsp pectic enzyme, SG. adjusted to 1.090, pH 3.68, nutrient and 71B-1122 yeast) this 10 batch completed fermentation at SG 0.990. After 2 rackings, it has yet to clear…even though I used a 2 part fining agent which I normally find very successful! I’ll try your suggestion of testing with more pectic enzyme and perhaps filtering. If this doesn’t work, I’ll just set it aside until whenever or turn it into ‘shine.

  5. A question / comment: I would think the hazy wine is still perfectly fine to drink, the haze having only a visual effect?
