Grape skin tannin for color stability and roundness
Scott’Tan™ Uva’Tan Soft is made entirely from white grape skin tannins extracted from fresh grapes immediately after pressing to avoid oxidation of polyphenols. These highly reactive tannins have very low astringency. Like Uva’Tan, Uva’Tan Soft can be used in fermentations as well as in cellaring and finishing. During fermentation Uva’Tan Soft is useful when the grapes’ natural tannins are insufficient and softness is a concern. Post-fermentation it can be used to stabilize color, soften structure and provide antioxidant protection. Used prior to barreling it can improve integration of tannins.
Additions of Uva’Tan Soft should be made well in advance of bottling (six weeks at least). Additions closer to bottling may still have a beneficial effect but filtration throughput will likely be reduced. At low dosages, Uva’Tan Soft will optimize the aging potential of white and rosé wines.
Red Must: 5–40 g/hL
White Wine: 5–15 g/hL
Rosé Wine: 5–20 g/hL
Red Wine: 5–30 g/hL
Pour Uva'Tan Soft evenly on the must/juice at the crusher or into wine during a transfer or racking. If further additions are required, two to three adds can be made after racking. Final additions can be made up to three weeks before bottling, though six weeks are recommended for a more complete polymerization, settling, and optimal filtration.
