Tannins are a group of phenolic compounds found naturally in the skin, seeds and stems of grapes used in wine, as well as in the barrels where wine is aged. 

Traditional methods of tannin determination require the preparation of specific reagent solutions and are demanding in time and preparation. The Tannins kit is based on the methylcellulose precipitable method (MCP), improving its usability and stability. The MCP technique captures both tannin types and pigment-bound forms, giving a clearer picture of a wine’s structure and future evolution.

Our analyzers use UV-Vis spectrophotometry, which measures light absorption at specific wavelengths associated with tannins. This provides an objective, accurate and reproducible measurement of tannin content, allowing the winemaker to control its extraction during maceration, its evolution during aging and its influence on the stability and final quality of the wine.
