Who Grows The Most Grapes In The World?

Grapes are grown throughout the world and in at least one country on every continent besides Antarctica. When it comes to table grapes, the country that is leading the pack in production is China, with over 14 million metric tons per year.

Following behind China is Italy with about eight million metric tons per year and then the United States with a little over seven million metric tons.

In the United States, Washington is the top producer of concord grapes. These grapes are table grapes and are often used to make that tasty grape juice you loved as a kid.

Or, as an adult, I’m not judging. Just because these three countries produce the most grapes per year doesn’t mean they produce the most wine per year, though.

The United States and Italy are still in the top three wine-producing countries, but China is not number one.

How Are Cotton Candy Grapes Made?

You’ve probably seen green grapes with the label saying cotton candy on them at the grocery store. If you’re anything like me, you’re probably wondering how on earth they got grapes to taste like cotton candy. The way cotton candy grapes are made is through cross-breeding.

Whoever is creating these sweet treats has to take pollen from male grape flowers and brush it onto the female flowers on the target plant. Cultivating cotton candy grapes takes a lot of time and patience.

Often, growers have to repeat this process for years before they finally get a grape that tastes like cotton candy.

The lengthy process could explain why these grapes tend to be much pricier than your average table grapes at the store or farmer’s market.

These grapes are higher in sugar than other table grapes, but they’re a fantastic way to get your picky eaters to eat more fruits.
