While we’re still in blackberry season, I thought I’d share with you a great tip to help make berries last longer in the fridge.  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 leftover from making delicious jam!

The secret to longer-lasting berries is quite surprising – vinegar!  I love using vinegar as a great chemical-free cleaner. However, who would have guessed that using vinegar can help fruit last longer in the fridge?


How to Make Berries Last Longer

To make berries last longer, 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.  Alternatively, fill a bowl with one part vinegar to three parts water and give your berries a short soak for a minute.

Next, drain the berries, and pop them in a salad spinner lined with kitchen roll. Gently spin until the berries are completely dry. Then decant the berries into an airtight container lined with kitchen roll, and place it in the fridge.

If you don’t have a salad spinner then gently pat the fruit dry with a clean (dark coloured!) tea towel. Then place them in the fridge in a sealed tub lined with a folded piece of kitchen roll to help absorb any water.

wash berries with vinegar

This method works because 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.  Meanwhile, completely drying the fruit also extends their life as well. This is because excess moisture speeds up the fruit’s decay, so keeping them dry slows down the rotting process.

Worried that your berries are going to taste of vinegar? Simply wash them immediately prior to eating, and you or your dining companions will be none the wiser!

Does It Work Though?

My verdict is yes, washing berries in vinegar and then drying them helps to make them last longer.  Berries that I have picked in the past generally have started to go off after 24 hours. However, using the vinegar and drying technique, I was able to stretch my batch to five days. It was at this point that I lost my nerve, and ate them! They perhaps could have lasted longer, however, I didn’t want to risk them rotting and wasting perfectly good berries!  Apparently, UK households waste 4.5 million tonnes of food a year, so anything we can do to reduce this is to be encouraged.
