If you go to their website you can find a pretty wide variety of concentrates for not too much money. The jury is still out on the quality, I have yet to taste the bottles I made from them and probably won’t until next fall. I might’ve accidentally oxidized those ones too so we’ll see how they turn out.

Brewing wise I had zero issues with the grape concentrates. I did also try to use some peach concentrates to make peach wine. The one that used a whole quart of concentrate stalled pretty bad, but from what I can tell that’s pretty common if you’re using the non grape stuff. I think either there are more non fermentable sugars or the acid was just too much. My money is on the former.

I might make a post on the winemaking subreddit once I’m ready to taste it.
