- When do you Add Tannins to Wine?
Actually, grape tannins can be naturally found in enough quantity in the grapes, so they do not need to be systematically added into wine. This will depend on the climate, the type of wine, the vintage and the goal of the winemaker.
Oenological grape tannins are especially recommended for under-ripe grapes or in the case of botrytis cinerea, which can infect mature or senescent plants prior to harvest, or seedlings.
They are used in several steps of the winemaking process: harvest, fining or aging.
- What are the Main Applications of Grape Tannins?
Commonly, grape tannins are used in red wine to facilitate stable pigment formation, stabilize wine color and improve its structure. In white and rosé wine, grape seed tannins reduce the quantity of unstable proteins. They help improve the overall wine balance.
Moreover, tannins can be used to enhance the natural antioxidant properties of all types of wine. That is why natural grape extracts, in general, are being increasingly used, for their multiple benefits, in different kinds of edible and drinkable products as well as in dietary supplements and even pharmaceutical compounds.
Technical Details & Test Data
- Proanthocyanidins: Condensed Tannins
Proanthocyanidins are condensed tannins and tannins are natural polyphenols found in wine, coming from grape skin and grape seeds. They are known for their beneficial properties, which influence the quality of the wine as well as the health of the consumer.
During the winemaking process, oenological tannins can be added to wine or must and, naturally, grape tannins appear to be the logical choice.
