Ever wonder how many grapes it takes to make your favorite wine?

Well, according to  800wine.com,
here is the approximate grape to wine ratio:

1 grape cluster = 1 glass
75 grapes = 1 cluster
4 clusters = 1 bottle
40 clusters = 1 vine
1 vine = 10 bottles
1200 clusters = 1 barrel
1 barrel = 60 gallons
60 gallons = 25 cases
30 vines = 1 barrel
400 vines = 1 acre
1 acre = 5 tons
5 tons = 332 cases

P.S.: If you’re a Pittsburgh native or from western Pennsylvania and make your own wine in September (for the holidays etc.), a great place to get your grapes is from Consumer’s Produce in Pittsburgh’s Strip District. Here’s a great old article about Consumer’s Produce from the Pittsburgh Post-Gazette.
