When you say you have made WE kits and they turned out well. How would you compare them to a commercial grade wine.
With Wine kits, you really do get what you pay for.
In my experience with WE, the cheapest kits ($65-80ish), I get a wine that is very much in the $5-7/bottle quality. Not bad, not great. They are not complex, but very drinkable and drinkable right away. These remind me of the Barefoot wines, or Two Buck Chuck. They are fine for everyday, and better than many boxed wines or jug wines.
The Eclipse kits, ($150+) make a wine very much like a $20+ bottle and age very well. They are complex, deep, and very good to excellent.
The 'in the middle' ones have given pretty good wine to us, comparable to $10-15/bottle type of wines. These are good enough to share with friends, and have some complexity to them. They age fairly well.
