How to stop Berries from Turning Mouldy and Soft in the Fridge

Strawberries come once a year – it’s a shame to see that they can go soft in a matter of days.  Today’s post is a simple trick that can prevent berries (especially strawberries and raspberries) from softening or moulding for a week or more.

How to stop Berries from Turning Mouldy and Soft in the Fridge Strawberry

The trick?  Rinse them quickly in cider vinegar before storing.  It doesn’t change the taste (you can rinse them again before using) but helps kill some of the natural wild yeasts on their surface and prevents them from going soft.

What’s your favorite trick for storing food?


  1. My trick is to put it in my mouth. ;) Glad to have this tip to try. I keep an eagle eye on berries and at the first hint of any turn toward the dark side, I toss ‘em in the freezer for addition to smoothies & baked goods.

    • Haha! Yes, but putting berries in your mouth is the opposite of making them last longer..then, again since eating them is the point I think you win! :)

  2. Totally helpful! Now to get some more raspberries….
    Interestingly, those wild yeasts will come in handy in the event I attempt to make a naturally fermented fruit juice….

    • Indeed Jon!

      I fermented some raspberries last weekend for a few days (no post yet) and they were delightful. Plan to try more this weekend. :)

  3. Thanks so much for this tip! I’ll certainly give it a try on strawberries. I wonder if it works for figs?

  4. how about heat shocking? that should work, from what i understand.

  5. I’ve never heard of this method, but I’m definitely going to give it a try ASAP! Raspberries, you will be mine… :)

  6. You really only need vinegar (white vinegar is fine) in a 1:4 ratio with water to rinse your berries, although I soak mine for a few minutes and then drain. Don’t rinse; you won’t taste the vinegar.
