Im on long Island NY. This will be my 3rd year making with with grapes, prior years were juice buckets. If I really wanted to and had free time, I could drive up to the finger lakes ( 5+hour drive), I could also drive to the North fork AVA which is about an hour thirty. I've seen listing of hand picked grapes out there, thinned for quality, etc. for $2600-$3000/ton which is similar to the price of the grapes I get from CA, maybe a little cheaper. I would assume these grapes are probably more cared for than the grapes in a bulk vineyard in CA so maybe they quality is better but who really knows. I also have access to Hudson valley ava and am there quite frequently, I'm sure I could find some vineyards willing to sell in small quantities. I just figured the fruit from CA would be the "best" that I can get.
What I like about the CA grapes is that there's a lot of variety. If I stay local, it's not as much variety. Pros and cons...
