Just how much wine?

Have you ever driven past a wine farm, looked at the endless vineyards and wondered to yourself just how much wine they produced or how many bottles of wine per vineyard you're looking at? Perhaps how many litres? Maybe you've looked at a wine bottle and wondered how many grapes it took to make that bottle? Here's a simple way for you to do the maths, no matter what you're looking at:

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
