Grapes have been around a really long time. In fact, the first grape varieties might date as far back as 6000 B.C.
Grapes from California, however, were not cultivated until1839 when a trapper from Kentucky planted the state’s first table grape vineyard in the Mexican colonial pueblo now known as Los Angeles. California grapes, available May through January, are now shipped to more than 60 countries around the world.

Health Benefits of Grapes
Research has shown that grapes of all colors – red, green and black – are a natural source of beneficial components called polyphenols, which are antioxidants. Grape polyphenols appear not only to protect the health and function of our cells; they may contribute to a healthy heart, and help defend against a variety of age-related and other illnesses.
Grapes provide potassium as well, and are a good source of Vitamin K. Potassium is essential for the heart, kidney and other organs to work normally, while Vitamin K plays a key role in helping blood to clot in order to prevent excessive bleeding and may also be important in bone health.
How to Choose Grapes at the Store
Look for grapes with green, pliable stems and plump berries. The powdery-white coating on the grapes is the “bloom” and it’s good! Bloom is a naturally occurring substance that protects grapes from moisture loss and decay.
Grapes keep for up to two weeks when handled properly. Store grapes unwashed in the refrigerator; rinse just before serving or adding to a recipe. Like most berries, grapes tend to absorb odors. Try to avoid storing them next to things like onions or leeks.
Ways to Include More Grapes in Your Diet
Grapes can be eaten fresh, frozen and as a wonderful addition of flavor and texture to anything from salads to sides, drinks to desserts.
- Replace grapes for tomatoes in salads like in my California Grape and Avocado Salad
- Roast them to intensify the flavor and include in savory dishes – try my Honey-Balsamic Chicken with California Grapes
- Use grapes in pies, crisps and cobblers to take them to the next level. My Mini Grape Crisps with Nutty Oat Topping is a delicious and healthy treat
