Product details

Many winemaking trials in recent years with Uvaferm HPS have shown the impact of yeast polysaccharides on mouthfeel contribution. In comparative trials with grapes such as Cabernet Sauvignon, Tempranillo or Merlot, wines fermented with Uvaferm HPS at the end of fermentation had an increased perception of mouthfeel, roundness and sweetness of tannins. In addition the wines are known for their strong varietal characters. Highly recommended for early release red wines.
