In a large bowl (I use a salad spinner) or sink, add 3 cups of water to 1/4 cup of white vinegar or apple cider vinegar.
Step 2: Soak
Let the berries (strawberries, blueberries, or blackberries) soak for about 5-10 minutes in the vinegar bath.
Step 3: Dry
Remove the berries, rinse with fresh water, and dry on a towel on the counter. Or, individually dry the berries with a towel. You don't want any moisture left on the berries before storing in the fridge.
Step 4: Store
Once dry, store the berries in a paper towel-lined container with a lid. If you don't want to use a paper towel, I've found the Produce Keepers from OXO also work extremely well for storing berries (no paper towel needed!).

Notes
Store the berries in the fridge for up to 2 weeks, or in the freezer for up to 6 months. If storing in the freezer, cut the green tops off first, then place on a parchment paper line baking sheet and freeze for 1 hour. Transfer to a freezer bag for long-term storage.Do not cut the berries if storing in the fridge, and don't remove the green tops. Cut berries don't last as long in the fridge as whole berries.This method only works for strawberries, blackberries, and blueberries. Raspberries are far too delicate to soak in water and vinegar. Just know that you'll want to eat raspberries fairly quickly and keep the berries in their original container. The one exception to this is if the raspberries are from the farmer's market and don't come in the pad-lined case. In this case, place the unwashed raspberries in a paper towel lined container.
