Clearing A Cloudy Wine...

Cloudy WineHi

What can I use to remove the cloudeness in my wine. Can you help? I've strained the wine 2 times and It is still cloudy.

Thanks John

Hello John,

What needs to be determined is, "why is the wine cloudy"? Is it from pectin cells in the fruit? Is it from suspended yeast cells? Is it from startches in the fruit? Or, is it because the wine simply needs more time to clear up? In any case, the problem needs to be solved, particularly if you plan on handing out your bottles of creation as wine making gifts.

The first thing that should be done is a reading should be taken with a gravity hydrometer. This will tell you if the wine has completed its fermentation. If the wine is still fermenting, even slightly, this would most likely be the cause of the cloudiness. In this case, just let the wine finish fermenting.

If the wine has completed its fermentation, you will want to see if the top half of the batch is more clear than the bottom half. If so, this would indicate that the wine just needs a few more days to clear up. After a wine has completed fermenting it usually needs a week or two to clear up. Most homemade wine instructions will indicate this time period.

Shop BentoniteIf you're sure it's been more than two weeks since the wine has completed fermenting, and it's still cloudy, then it may be time to start using wine making products such as fining or clearing agents.

Treating the wine with bentonite would be the first step I would suggest. It's an affective fining agent that most likely will solve your problem completely. But, if you see only marginal improvement, you should switch to Sparkolloid. In general, Sparkolloid will take out what bentonite doesn't and vice versa.

If the bentonite clears the wine almost completely, but there's still a slight murkiness, then you should switch to a polishing clarifier such as our Kitosol 40. You might want to check out the article, Using Finings To Improve Your Wine. It will give you more detail about fining agents and other wine making products you can use to clear your wine.

Happy Wine Making

    I made a blueberry wine. waited for the fermentation to stop. which was 6 weeks. Racked it 4 times. added concentrated grape juice and wine conditioner before bottling. It was in the the bottles for 1week and started fermentation. I than opened all bottles into a bucket and added potassium sorbate and camppen tablets.Should i bottle now or wait until it stops working?

    It's important to make sure the wine has completed its fermentation. Just as important, the wine needs to be completely clear before bottling.

    My first batch of Chardonnay cleared nicely. To try to maintain that beautiful clarity I racked to another vessel for bottling. As you might guess a tiny bit of sediment got stirred up and made its way to the bottling bucket. Now there is a very slight haze to the wine. Next time I do this I want to rack the wine before bottling and then let it sit for another week to allow any transferred sediment to settle. Is this a good idea?

    Peter, you have to be aware of the negative effects that too much air exposure can have on a wine at this stage of the process. If there is very little head space in the bottling bucket, then okay. But if there is air space in the bucket, I would be hesitant to keep the Chardonnay in there for any extended period of time.

    Mr. Geoff Hey, if the wine truly does have a pectin haze problem, there is little more you can do other than add a pectic enzyme of some kind. Realize, that the pectolase you added will not work fast. It will require some time, so all you may need is a little more patience.

    Jerry, it sounds like your wine is experience acid precipitation. This is when there is more acid in the wine than the wine can hold, so it crystallizes and drops out. It is something that is created after filtration. There is a lot more information about this in the following article on our website:

    Bev, it sounds like the wine never finished fermenting, and now it is fermenting in the wine bottles. Be very, very careful. Your wine bottles could be building up pressure, to the point where they could start exploding or popping corks. Assuming this is the case, you need to put all the wine back into a fermenter and let it finish the fermentation. Having a hydrometer to take readings would tell you if the fermentation has finished or not. If you do not have one, I would suggest that you get one.

    My wine is from red grapes. my hydrometer reading is 1000.00 today. I started this wine on 9/28/13, it has been fermenting since then. I just syphoned it into a smaller carboy for less air space. I don't plan to bottle for at least 6 more mths. It is very cloudy, how can I clear this up? It also taste very strong, bitter like nail polish, any suggestions for sweetening?

    Customer Service says:

    Shirleann, it is extremely likely that your wine is turning to vinegar. Alcohol fermentations are normally finished in a few days, not months, so any activity you've been seeing this year is probably not from the yeast, but rather, vinegar bacteria (acetobacter) turning the alcohol into vinegar. These fermentations can continue for months if not years. Another classic tell that your wine is turning to vinegar is the nail polish odor. This is precisely what a vinegar fermentation smells like. At this point there is nothing you can do. You can not reverse what has happened, and it is not likely that you would want to drink the wine. Vinegar fermentations can be avoided by using sulfites such as Campden tablets or potassium metabisulfite in the wine, and by sanitizing your equipment and containers with a sanitizer such as our Basic A.
