What is wine stone?

We will briefly explain how it is formed, how it looks like, and where it is used.

Wine stone is deposit made from salts of tartaric acid. Tartaric acid exists naturally in the grape must and reacts with other substances during the fermentation, causing its salts to precipitate along with the yeast. Wine stone can also form in the bottles in finished wine.

The stones often take a beautiful, ruby appearance, and under a microscope they look similar to corals.

Tartaric acid, or wine stone, is a healthy natural product used in cooking and in medicine. It is also popular among people seeking a healthy lifestyle.

Wine stone is naturally only found in natural wines. In the wines of Arba Wine you can often encounter this beneficial ingredient.

Now you know what the wine stone is all about.

Best wishes from your Arba Wine!
