Wine Filtration: How Does it Work

For thousands of years, wine has been a popular beverage. In ancient Greece, wine was so important that it gained religious importance. They considered wine “the juice of the Gods” and still refer to it as such. Its taste, characteristics and effects all contribute to a natural liking for wine.

What is wine?

Wine is an alcoholic drink that originated from soured grapes. In addition, there are fruit wines or country wines extracted from soured fruits. However, the wine found in most bottle shops comes from wine grapes. The majority of wine grapes are Vitis vinifera species. 

How do you make wine?

You can make wine from table grapes, but it would be highly diluted and watery. So most winemakers control the natural sugars and yeasts to create the desired taste. In some regions, they add sugar to make it higher in alcohol. 

Wine absorbs enzymes during fermentation, preventing harmful autochthonous yeast from reproducing and outnumbering the good yeast. As a result, enzymes cultivate and possess different advantages for winemakers. In addition, most wines are not vegetarian. 

Winemakers use animal products such as egg whites, gelatin, and clay to refine and filter the wine. After purifying agents, the wine goes through massive machine filters to filter out agents and particles used throughout the process. 

Wine filtration techniques

Filtration is a technique used by winemakers to filter the wine and remove sediment and haze. Filtration stops the wine from becoming hazy and re-fermenting in the bottle using one of several methods. One primary reason winemakers filter their wine is to create its look and characteristics. 

In addition, filtration improves the microorganism stability of the wine, which prevents premature spoilage that makes a wine undrinkable. Filtration procedures differ depending on the winery’s size, the budget, and the quality of the wine. 

Gravity-feed and pressure systems are the most common filtration technologies. Gravity-feed filter systems that provide coarse filtration are inexpensive and best for small amounts of wine. However, these systems can’t do fine wine filtration.

To do this, you need a pressurised filter system that enable faster processing times and finer filtrations. These features make them more appealing to larger wineries. Pressurised systems also provide more value and move wine through a perpendicular flow towards the filter. 

The system creates clean wine once particles become captured. However, these particles build up, inflicting pressure on the filter, decreasing the flow. Therefore, once the filter reaches a termination purpose, the vintner should clean the system before using it. 

There are several varieties of depth filters used for making wine. These include pressure leaf, plate and frame, cartridge and biconvex. The first step of depth filters is pre-filtration, which involves removing the larger particles in suspension. Them the wine moves through a sheet to reduce yeasts and microorganisms. Finally, sterile filtration occurs once the wine is as clear and bright as desired.

Choosing a Wine Filtration System

When choosing a filtration system, it’s best to determine the volume that needs filtration. Since every filtration pad rating is helpful for varied levels of clarification, wineries might benefit from keeping multiple pad varieties available.

Wine manufacturing starts with taking care of the grapes before harvesting and ends with bottling the final product. A wine’s attributes can vary greatly. They rely on a genuine range of influences such as environment, yeast, and fining alternatives.

However, most wines require filtration to encourage a beautiful appearance, keep the product free of deposits, and keep the wine stable, chemically and biologically. Based on our FLTR experience in the filtration industry, we provide reliable filter media and equipment for all stages of wine filtration.


Winemakers place a premium on the colour and flavour of their wines. Therefore, filtering wine is an essential step in the last stages of wine and sparkling wine production. Filtration ensures microbiological stability and quality.
