How Many Grapes are in a Glass of Wine?

Wine FiguresThis is like guessing how many jelly beans are in a jar.  10,000 grapes in a glass of wine?  1,000? 7?

The Sonoma County Grape Growers Association has, quite handily, worked it all out for us.  What would we do without associations? Okay, here goes.

An average vineyard yields about 5 tons, or 10,000 pounds, of grapes per acre.  (Right off the bat, we’re in dicey territory. 

The best vineyards and those that make the most expensive wines produce far less.  Still, we continue.)  All of those grapes make about 13.5 barrels of wine, which is 797 gallons.  That equals 3.985 bottles.  Are you still here?

When you do the math, it turns out that one bottle of wine is made using about 2.4 pounds of grapes, so one glass is made from about 10 ounces of grapes.  This depends on all sorts of factors from weather, to practice, to type of grape and style of wine.  But it’s a pretty decent average.

Of, course, the Napa Valley Vintners Assn. has slightly different figures.  Only slightly, but God forbid that associations should be in agreement!  Anyway, they say that a ton of grapes makes on average 720 bottles of wine, so each bottle contains about 2.8 pounds of grapes.  It also tells us that one average vine produces enough grapes to make 4 – grapes 6 bottles of wine each year.

We want to know what size of wine glass the associations are using.  Because, we are certain our glasses are larger than the ones they are using to measure the number of per glass.  So, here’s to you, and may you enjoy your bottle of, about, 2 ½ pounds of grapes.

We believe in savoring every last drop!
