What is the difference between hard tannins and soft tannins?

In order to preserve you need tannins. The skin of the grape is where we get the tannin that astringency. When the grapes have not matured properly, we also get tannin from the seeds. And so we refer to hard tannins and soft tannins. Hard tannins come from the seeds, the soft tannins come form the skin. We need those tannins to make the wine age. To make the wine age gives it character, it is something that is sort of this alchemist thing. As it develops in the bottle, it gives off this wonderful bouquet, and it gives the richness, gives the poetry of like a novel a writer that can put the words together that create the magic. But you need the tannin; you need the drama that's there.
