How to Clarify Wine – The Best 6 Methods

how to clarify wineOne of the most common questions we hear from new winemakers is how to clarify wine. Getting that crystal clear wine is something many home vintners really strive for. There are really many different techniques you can take that will lead you to clear wine. Some are more aggressive and expensive than others. Some of them are more of the traditional type of additives that have been working for years. While others are newer chemical compounds that will get the job done fast. There are a couple of different reasons for cloudy wine. The main cause is particle haze. Meaning there are small particles still floating around in the wine. The other primary cause is pectic haze or the pectin from the fruit being suspended in the wine mixture. Let’s talk about several ways to clarify wine.

If you’re new to winemaking then you’ll want to take a look at our post on how to make homemade wine. Then save this article for when you are getting close to bottling time.

How to Clarify  Wine Using Gravity

For the longest time winemakers would simply let their wines site for an extended period of time and let gravity do its job and collect the particles at the bottom of the fermentation vessel. Since the particles are heavier than the liquid that they are suspended in they will eventually sink to the bottom if given enough time. When we talk about how to clarify a wine this is always the first step. Just give it more time is something you probably don’t want to hear but it’s pretty common. Letting the sediment settle and then siphoning off the liquid is the primary way to clarify a wine. Aging and racking should always be your first step in clarifying your wine. If you’re in more of a hurry there are some other options out there.

Clarify a Wine Using Pectic Enzyme

pectic enzymePectin haze is a common cause of cloudy wine. This is especially true for fruit wines. Peach wine, for example, is notorious for having trouble with pectin haze. The pectin from the fruit becomes suspended in the liquid mixture causing a cloudy appearance. The addition of a pectic enzyme additive prior to fermentation will help to clear wines with pectin haze. The pectic enzyme will assist in breaking down the fruit that you are trying to extract your juice and flavor from. Because the pectin is still intact after you crush the fruit the addition of the enzyme will break down the structure of the pectin. This will prevent the pectin from formin a haze in the finished wine. The pectic enzyme also aids in filtering as it keeps your filter from being plugged with pectin. For the most part it’s a good idea to add pectic enzyme to all of your wines to help the wine clarify and clear.

Clarify a Wine Using Bentonite

bentoniteBentonite is a type of clay mineral that has been used as a clarifying agent in wines for some time now. It comes from a form of volcanic ash. of volcanic ash. It is an absorbent material that is able to bond with the floating particles that cause cloudiness in wine. It can be added to the wine at any phase and is typically introduced as a slurry mixture of water and bentonite. Some people think that adding bentonite during fermentation allows the particles of bentonite to be pushed up through the wine by the co2 and attached to the other particles and drag them to the bottom. Other than that it can also be added during aging and slowly help to draw the floating particles to the bottom of the carboy. You usually only need to add 1-2 tablespoons of bentonite to some water to make a slurry and then add it to your wine.  Add the mixture to your wine and stir vigorously, then just wait and let it do its job. There is really little downside to adding bentonite to your wine and it’s relatively inexpensive and natural.

Clarifying Wine Using Egg Whites

egg whitesSome of you may have heard about this while others will think this is a bit strange but adding egg whites to wine is another way to help clarify it. This method is one of the oldest techniques to clear wine. Egg whites are made up of albumin and globulin which are positively charged. This causes the negatively charged particles in the wine to be attracted to the egg whites. The egg white forms a bond to the particles and tannins and they attach together. This will make the wine look cloudier at first but eventually, the particles will sink to the bottom of the wine. This technique is more suitable for red wines as the egg whites are most attracted to the tannins. This doesn’t work out as well for white wines. One egg white should be plenty for a 5-6 gallon carboy. Add the egg white and stir then let it sit for about 2 weeks before racking.

Clarifying a Wine Using Sparkolloid

SparkolloidOne of the things that come to mind when you think about how to clarify wine is some type of chemical additive. One of the newer chemical clarifying agents is known as Sparkolloid. This fining agent is actually best used after bentonite. While bentonite will take care of many of the larger particles, Sparkolloid will take care of the rest. It’s really good at fining the wine. Sparkolloid can technically be added any time after fermentation stops but usually, it’s after bentonite has had time to work. Sparkolloid powder is able to take out the finer particles that bentonite can miss by neutralizing their electrical charges and allowing them to drop out of the wine. On its own, Sparkolloid is not that good at attaching to larger particles so you will want to use it in conjunction with bentonite.
