So ive made wine from grapes as a kid on a huge scale, and ive made wine from buckets of juice in the last few years, so decided to make a cab from grapes on a small scale (2x36lb lugs) this year. I punched the cap ~4 times a day, and just did my first rack about 5 weeks after primary fermentation. As always during racking, I take a small tasting just to make sure its going in the right direction. Ive never tasted something this flavor-strong before. It almost had too much body, almost a little tart. Is it turning to vinegar? Will it mellow out? Did I punch the cap too much?
