Œnological products

Wine profilers

Made from a selection of natural products, Demptos tannins and yeast derivatives are designed to enrich, correct, adjust, balance and improve the stability of wines.

Tannins are known to play an important role in the transformation and evolution of wines during the maturing process.

Oenological tannins

Hydrolysable or condensed, the function of the tannins proposed by Demptos varies according to their nature :reinforce wine oxidation, help to stabilise the colour, colloidal substance or profile for a better balance.

Yeast derivatives

Yeast derivatives act according to their nature on the wine’s structure and evolution. The polysaccharide fraction of certain types of derivatives acts on the colloidal structure of the wines to improve their stability and taste properties, while the nitrogen/sulphur fraction of other derivatives, which act like competing antioxidants, limits the evolution of the wines and protects their most sensitive components: aromas and colour.

Produced by biotechnology using only natural ingredients such as oak or grapes, Tech in Wine® oenological products are the result of collaboration between the Demptos Research Centre and its partners, university laboratories or research centres.

Which oenological tannins hould I use to reinforce the structure of a red wine?

Thanks to its active white grape pipprocyanidols, Profil’Seed®Polymer reinforces the structure and body of red wines that are lacking in structure. It also has antioxidant properties and helps stabilise the colour of the wine.

In what form are the tannins and yeast derivatives delivered? Can they be stored without deteriorating?

The tannins are delivered in 500-gram vacuum-sealed aluminium food grade bags, while the yeasts come in 250-gram bags. Tannins and yeasts should be stored in their original packaging and kept away from sources of heat and humidity.
