Refrigerator: Up to 2 weeks
Tip: Do not wash the grapes before storing, as too much moisture will cause damage. Also, make sure to place them in the fridge as soon as possible after purchase.
The best place to store grapes is in the fridge as the ideal temperature for them is 0-2 degrees celsius. Separate stacks of grapes to promote air circulation, store in a ventilated plastic bag or on a plate and place at the back of the refrigerator where it’s the coolest.
