Why You Need to Wash Grapes

Grapes belong to the Dirty Dozen—an annual list of produce with the highest levels of pesticides, compiled by the Environmental Working Group. The EWG recommends splurging on organic grapes, but not everyone can afford to buy organic produce, which can get quite expensive. If you opt for regular, non-organic grapes, take extra care when you’re cleaning them to remove as much pesticide residue as possible.To clarify, the whitish film you often see on grapes isn’t from pesticides; it’s called “bloom,” a waxy coating produced by the plant itself to protect the fruit. While the bloom is safe to eat, it can taste bitter and chalky, so we suggest thoroughly washing your grapes, whether or not they’re organic.

When to Wash Grapes

Hold off on washing grapes until you’re ready to eat them! The washing process adds excess moisture, which can cause the grapes to decompose faster than they otherwise would. While it seems practical to wash all of your grapes as soon as you get home from the store, you should actually only clean what you plan to eat right then and there, or in the near future. The aforementioned bloom helps keep the grapes fresh, so it’s best to avoid washing it off until you’re ready to snack on some fruit. For ultimate longevity, keep unwashed grapes in a plastic bag in the refrigerator until you’re ready to clean and consume them for a sweet-sour treat.

How to Wash Grapes

Washing grapes isn’t complicated, but there are certain steps you should follow to ensure your grapes are as clean as possible.

How to Store Grapes After Washing

While you should avoid washing grapes until you’re ready to eat them, we have a few tips for storage if you’ve gone ahead and washed them anyway. First, let them dry as completely as possible after they’ve been washed. This is because excess moisture can lead to faster spoiling. Once dry, store grapes in a ventilated bag in a cold spot of the refrigerator. The air flow and chill will help preserve the fruit for about three weeks.
