What Are Moon Drop Grapes?

These funny looking grapes are a delicious treat.

If you’ve spotted grapes in the produce aisle that are much more cylindrical than the usual varieties, then you’ve seen Moon Drop grapes, also known as Sweet Sapphires. First developed in California in 2004, Moon Drop’s unique shape definitely helps it stand out among the other grape varieties. 

What Are Moon Drop Grapes?

A type of black grape that largely is available in late summer and fall, Moon Drops have a number of qualities that make them a fantastic choice for anyone who loves snacking on fruit. Fans of slightly tart grape juice will also be thrilled to know that Moon Drops contain the candied fruit flavor of artificial grapes, but in an actual fruit form.

This new strain of grapes was also developed to last longer in transport and storage than other commercially popular varieties. That means that once they’re in your fridge, they should last for quite a while.

How Were Moon Drop Grapes Developed?

Moon Drop grapes are the product of agricultural experimentation, but they are not an example of genetically modified plants. They first came into existence in 2004, created by International Fruit Genetics (IFG), which was founded by Dr. David Cain in 2000. So while their shape, texture, or taste might seem like a GMO invention, they are simply an example of the kind of fruit nature will grow if given a nudge.

Unfortunately, Moon Drops cannot be grown at home. They are under patent protection until at least 2031.

Why Are They Called Moon Drop Grapes?

IFG, which developed the grapes, trademarked them Sweet Sapphires. The name Moon Drop Grapes, however, comes from store naming. It’s possible that the grapes received the name because of their vague resemblance to a water drop. In some markets, they are also called witch's finger or teardrop grapes. In my local stores, shoppers seemed to largely refer to them as “long grapes.”

What Do Moon Drop Grapes Taste Like?

On average, Moon Drop grapes are sweeter and have a more intense grape flavor than more readily available varieties, like Concord. For me, Moon Drops consistently tasted like concentrated Welch’s grape juice that had been mixed with less water than directed. That slightly candy-ish flavor is comparable to the Cotton Candy Grapes (also an IFG creation) that have also been developed through artificial hybridization over the years. 

Picky eaters, people with sensory issues, and those who struggle with texture may find a friend in Moon Drop grapes because of the way they have been developed. In general, Moon Drop grapes have a firmer texture than other varieties of grapes. Some you are even able to snap in half.

They are also seedless and consistently firm yet yielding throughout. For those who find it difficult to eat fruit with inconsistent textures, Moon Drop grapes may be a way to add produce back into the snacking repertoire. 

What to Look for When Choosing Moon Drop Grapes

As mentioned earlier, Moon Drop grapes were developed to last a long time and be extra durable during shipping and storage. That being said, it’s still fruit and does eventually go bad, and it can still be damaged in transit.

When picking out Moon Drops at the store, look for grapes that are oblong with a slight dimple at the end. The grapes should be plentiful on each bunch, and each grape should be firm. Loose grapes that have fallen off the bunch should be checked to make sure they have not started to turn.

Once home, Moon Grapes should last quite a while when stored correctly. I was able to enjoy them for about two weeks before the last few began to wrinkle. Kept properly, these grapes can become a great addition to your fruit rotation.
