fi /

trū/tan fi is a hydrolysable blend of gallotannins and ellagitannins, with a total tannin range of 95% to 99%. This tannin blend was developed with fermentations in mind — its high tannin content helps preserve aromatics in whites and benefits color stability in reds. trū/tan fi is also useful during finishing at lower dosage rates to accentuate fruit by bringing it to the forefront of the aromatic profile. The tannin addition preserves aromatic character through antioxidant reactions and increases overall structure.
