How Many Pounds of Grapes Per Bottle of Wine?

I actually thought this was an interesting question, but as the kids say in elementary school:

Warning: Math

Ok, so let’s start with the basics. To figure this out, we’ll need to get I’ll have to simply give you the first part of this number and then we’ll work backward. A ton of grapes yields somewhere from at least 110 gallons of wine, up to 180 tons depending on a number of factors including farming practices and varietal of grape in question. Just as an example, if a farmer waters the grapes the day before they’re harvested, there’s suddenly more grapes (IE more water weight) which is something that winemakers struggle against consistently.

Let’s make our life easy though and say that we receive 150 gallons of wine from each ton of grapes.

So that’s one of our inputs, but the question now becomes, how many bottles of wine do we receive from that same ton of grapes?

Now, we have another known quality, a bottle of wine is 750ml. To get this into gallons, it’s actually easier to use a case of 12 bottles of wine, which is 2.378 gallons (you’ll sometimes see this listed on cases since this is how tax is collected for wine).

So each ton of grapes gives us 63 cases of wine, more or less a pallet which does make life at a winery a lot easier.

63 cases is actually 756 bottles of wine.

Ok, so now we know that a ton of grapes produces something around 750 bottles of wine. So how many pounds of grape per bottle of wine? There are 2,000 pounds in a ton (about half the weight of your car).

Since we’re now in the same units this is easy enough, there are 2.67 pounds of grapes per bottle of wine. To put that in perspective, a bag of grapes sold at your local Whole Foods weighs on average, 2 pounds.

So how many pounds of grapes per bottle of wine? The answer is 2.67, but it’s probably easier to remember it’s about two and a half pounds, or about the normal weight of a bag of grapes at your local grocery store. Which if we’re estimating, makes sense based on size right?
