Juicy grapes are a summer staple, but their short shelf life can be frustrating. Thankfully, there’s a simple trick to keep them fresh for up to six weeks, according to food storage expert Amy Cross. The key lies in washing the grapes properly when you get them home.
Cross explains that grapes have a high water content and thin skin, making them susceptible to bacteria and spoiling quickly. However, by soaking them in a vinegar solution, you can effectively eliminate bacteria and extend their freshness significantly.
Here’s how to store your grapes for maximum longevity:
1.
Wash and Cut:
As soon as you bring your grapes home from the store, wash them thoroughly and cut the stems into smaller portions, keeping them attached to the fruit. According to Cross, leaving the grapes on the stems helps them last longer by preventing oxygen from reaching the fruit.2.
Vinegar Soak:
Place the washed grapes in a large bowl with cool water. Add 240 ml of white vinegar to the bowl. Vinegar’s acetic acid acts as a natural antimicrobial agent, killing bacteria, mold, and any residue on the grapes. Allow the grapes to soak for a maximum of two minutes to prevent them from absorbing a vinegary taste.3.
Rinse and Dry:
After the two-minute soak, drain the grapes using a colander and rinse them thoroughly with fresh water.4.
Air Dry:
Spread the grapes in a single layer on a clean tea towel or paper towel and let them air dry at room temperature for a few hours. This step is crucial for preventing moisture buildup, which can lead to mold.5.
Store in an Airtight Container:
Once completely dry, place the grape stems in a large, airtight glass container with a lid. Cross recommends using a paper towel at the bottom of the container to absorb any moisture. Glass is a non-reactive material, unlike plastic, which helps preserve the grapes for longer.6.
Refrigerate:
Store the container in the refrigerator. By following these steps, you can enjoy your fresh grapes for up to six weeks longer than usual, saving you money and reducing food waste this summer.Remember, proper storage is key to keeping your fruits and vegetables fresh and flavorful for longer. With this simple vinegar soak method, you can enjoy delicious grapes all season long.
