Can somebody recommend a tannin for my cab? I made 120 litres last year, aging for a year, tastes okay, still a little young. I'd like to improve mouthfeel specifically. I'm looking at the morewine website and would like to purchase tannin but not sure which one. They got a few types of tannin from Scott Labs: Rouge, Complex, and Riche. Can somebody make a recommendation? Thanks!
