Scott’Tan™ Uva’Tan Soft is made entirely from grape skin tannins. They are extracted directly from fresh grapes after pressing to avoid the oxidation of the polyphenols. These highly reactive tannins are characterized by very low astringency. Like Uva’Tan, Uva’Tan Soft can be used in fermentations as well as in cellaring and finishing. During fermentations Uva’Tan Soft can be 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 anti-oxidant 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) for a more complete polymerization. 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.
UsageSprinkle Uva’Tan Soft evenly on the must at the crusher or into the wine during a transfer or racking. Further additions can be during the next 2-3 rackings followed by organoleptic evaluation. Final additions can be made up to 3 weeks before bottling though 6 weeks are recommended to ensure complete polymerization, settling and optimal filtration.
