A 10g grape-tannin addition for building structure, flavour and astringency in wine.
How to use
Start at 5g per 100L, mix thoroughly, then taste before adding further 5g increments as directed.
Helpful information
Scale accurately for small batches. Tannin is difficult to remove once overdosed, so make additions gradually.
