I currently have a few batches going that I made from Alexander's concentrate. I did add some fruit to each to dress it up a bit, but the recipe on the can does not require it. I have heard that these are not as good as kits, but I couldn't tell you personally since these batches are still going and I have not had a chance to taste them yet.
I guess it matters how expensive your wine tastes are. If you like fairly expensive wine, then I would guess you will be disappointed. Luckily I'm still on the cheap stuff!
These cans are fairly inexpensive at between 13-20 dollars per can. It calls for 2 cans for 5 gallons.
