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.  Are you curious to learn more about measuring tannins?

After a cool growing season, harvest 2025 was sprinkled with unwelcome weather events, making even ripening merely a dream for many winemakers. As fermentation wraps up, the young wines may still express raw or green tannin character, needing time to mellow and come into harmony. Post-fermentation aging and finishing tannins are an essential tool for taming those unruly characters to achieve balance, structure, and true aromatic expression. These post-fermentation tannins refine green or unripe fruit characteristics, improve mouthfeel, and smooth rough edges, to bring the wine back into harmony. Red Wines: From Green to Graceful If the winery has the cooperage space and time, extended aging is used to refine rough young red wines. Alternatively, aging tannins address gaps in structure or smooth the perception of green fruit, particularly in this cooler vintage. Carefully selected tannins can build mid-palate weight, stabilize color, and add complexity for a wine that will age gracefull
