While we’re still in blackberry season, I thought I’d share with you a great tip to help extend make berries last longer in the fridge before going off. Not just blackberries, but raspberries, strawberries, blueberries, and any other berry you can care to think of. This is especially great if you’ve picked more blackberries than you can eat or have some left over from making delicious jam!
The secret to make berries last longer is quite surprising – vinegar! I love using vinegar as a great chemical free cleaner, but who would have guessed that using vinegar can help your berries to last longer in the fridge?
How to Make Berries Last Longer
According to Cooks Illustrated all you have to do is rinse your berries in a solution of one part vinegar (white vinegar or apple cider vinegar works best) to three parts water. Then dry the berries in a salad spinner lined with kitchen roll until completely dry, and store in a kitchen roll lined airtight container to help make berries last longer.
I don’t own a salad spinner and I’m not about to go out and buy one to add more plastic to my kitchen, so instead I filled a bowl with one part vinegar to three parts water and gave my berries a short soak for a minute. Then I drained and rinsed my berries, and gently patted them dry with a clean (dark coloured!) tea towel, before placing them in the fridge in a tub on top of a folded piece of kitchen roll to help absorb any water.
Ready to go in the fridge!
Cooks Illustrated say that the vinegar wash acts as an antiseptic agent – helping to remove any spores or bacteria on the surface of the fruit that can cause mould. I think the act of completely drying the fruit may also play a factor in extending their life as well, as I’ve found that washing berries without then drying them before storing them always speeds up the rotting process.
My verdict is yes, it indeed helps to make berries last longer. The berries that I have picked in the past started to go off after 24 hours, but using the vinegar and drying technique I stretched this batch into lasting two days. It could have been more but I didn’t want to risk them rotting and wasting perfectly good berries so we ate them! And to dispel any worries: no your fruit doesn’t taste of vinegar!

update: my berries lasted a whole week!
