Wine Crush: How Diatomaceous Earth Plays a Role in Wine …
The wine-making process is extensive with many steps, but toward the end, something particularly important happens: the wine goes through a filter to remove gelatinous or deformable materials that you don't want to see in your glass. Diatomaceous earth, also known as diatomite and DE, is one of the filtration methods used for wine.

global producer and consumer of diatomite. Filtration (including the purification of beer, liquors, and wine and the cleansing of greases and oils) continued to be the leading end use for diatomite. An important application for diatomite is the removal of microbial contaminants, such as bacteria, protozoa, and viruses in public water systems.
Liquid assets: the surprising role of minerals in wine filtration
For decades, minerals such as diatomite and perlite have played a vital role in the process – removing unwanted substances and leaving wine producers with clear, quality wines. In 2020, it was estimated that between 253.9 million and 262.2 million hectoliters of wine were produced across the globe – enough to fill more than 10,000 …
