Enological tannins offer the winemaker the possibility to add refined, highly-bindable tannin to your wine at any stage during the process. Benefits can include increased structure and mouthfeel, color stabilization, stability, anti-oxidative qualities, and overall complexity. Tannins can reduce vegetal/herbaceous characteristics and perceived astringency. We offer four types of oenolgical tannins, two for use during fermentation, and two for use during the aging phase.
How Fermentation Tannins Work Designed specifically for North American red wine fermentations, Scott'Tan FT Rouge is composed of exotic wood and chestnut tannins. These highly reactive tannins bind with anthocyanins (color compounds) in the first 3-4 days of fermentation. If sufficient natural tannins are not present in must, anthocyanins may precipitate, resulting in a loss of color. Using an enzyme like Lallzyme EX in conjunction with FT Rouge can enhance this binding of color. The continual bonding going on throughout the ferment will also improve the mid palate structure and help either significantly reduce or eliminate vegetal/herbaceous characters. Tannin additions at this early stage prove to be most efficient and are better integrated into the wine.
Important!: If being used in conjunction with one another, tannins should be added 6-8 hours after the addition of the enzymes or you run the risk of having the tannins reacting with and removing the enzymes before they have had a chance to do their job!.
Sprinkle directly onto must and either mix well with your punch down tool or pump over to ensure thorough mixing. If adding to the wine post-fermentation we recommend allowing 3-6 weeks for full integration before racking, fining, filtering or bottling.
Recommended dosage rate: 0.8-1.9 g/gal. Use at an initial rate of 1.3 gram per gallon during punch down/pump over. If you want additional tannin add at a rate of .25 g/gal.
A rough approximate of weight is 1 tsp = 2.4 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.
Unopened the shelf life is 5 years at 18ºC(65ºF).
