You already know that fermentation tannins are one of the most reliable levers you have for shaping structure, protecting color, and setting a wine up to age well. Added before or during fermentation, they protect juice from oxidation, stabilize red color as it's extracted from the skins, and reinforce overall structure—work that pays off long after the CO2 bubbles stop. This is especially true in weaker vintages, where the fruit may not deliver enough natural tannin to build a solid foundation on its own.
ATPGroup's full tannin portfolio gives you the right tool for every stage. Tannica Vintage is a fermentation tannin built to reinforce structure and early freshness, when your must needs it most, ideal for rounding out lighter or underripe fruit and giving every lot a stronger starting point. Color-Tan and Color-Tan NT rapidly stabilize color while building a smooth, full body and rounded structure, and can be particularly helpful with tannin-deficient or Botrytis-affected grapes. And when the fermentation is hot and color stability is the priority, Color-Tan Thermo binds with anthocyanins to lock in red color as it's released from the skins, delivering the durable color protection that makes your wine stand out all the way to the bottle.
Tannins are one of the most versatile tools available to winemakers. The trick is using them for the right job at the right time. Want to dig deeper? Click here for a closer look at tannin sources, applications, timing, and best practices:
