Just opened a 24 month old bottle of RJS Cru Select Ripassa - the longest aged of any of my kit wines. The oak and tannins just haven't mellow out, but it's drinkable. Looked back at my notes and fermented for 14 days till dry at .990 SG, started at 1.10. That's about 14.75 % alc. The kit came with 4 packs of oak and a really big bag of dry-sangiovese grapeskins. My point is, 12 premium red kits later non have had that much alcohol, oak or tannins, even with the usual added tweaks.
