Most people enjoy fresh berries, but they often spoil a lot faster than other fruits. Moisture, temperature and their handling all affect how long berries stay fresh.
If you’d like to know how to make your berries last longer, and what you can do to stop your berries from spoiling too quick, keep on reading…
Why Berries Go Bad So Quickly
Even when they look perfect at the store, berries start breaking down fast because they’re incredibly delicate and full of moisture. Their thin skins bruise easily, and once cells are damaged, juices leak out and create prime conditions for mold growth.
High moisture levels on the berries, allow microscopic spores to latch on, and they spread quickly, spoiling your whole container of berries in days.
Temperature fluctuations make a difference too, from the store, your cart and car ride. Each shift from cold to warm, and back again, causes condensation on the berries, and this extra surface moisture ends up speeding up decay.
Packaging matters too. Closed containers trap humidity, and any crushed berries hold in excess moisture, instead of letting it evaporate.
Choosing the Freshest Berries at the Store
When you’re choosing a punnet of berries, always check ripeness first. Look for firm and plump berries, that are vibrant in their color, and look dry. Make sure you avoid any berry punnets with visible juice stains, shriveled fruits, or any visible mould.
Consider berry varieties and their seasonal availability. Strawberries, raspberries and blackberries all last longer, when they’re in season, because they’re usually harvested closer to peak quality.
If you can, choose berries that are locally sourced, as they’ll have shorter transport times, with less handling, giving you a longer shelf life.
Organic berries will spoil at similar rates, but they’re often picked closer to ripeness, and handled more carefully, which can improve both texture and flavour.
Right Way to Wash Berries Without Ruining Them
Don’t wash your berries until you’re ready to eat them, or prep them. Place the berries in a colander, or a mesh strainer, and avoid soaking the berries in the sink, as they’ll absorb dirty water.
When you’re rinsing your berries, run cool water over the berries, and move them lightly with your fingers. Don’t crush or rub the berries, just lift and swirl them around.
If you need to do a deeper clean on the berries, use a vinegar solution (mix one part white vinegar with three parts cool water), and briefly swish the berries, then rinse thoroughly with plain water to remove any tang.
Finish by drying your berries properly. Spread the berries out in a single layer on a clean kitchen towel or paper towels, and pat them dry without pressing too hard.
Where to Keep Each Type of Berry in Your Fridge
For strawberries, keep them on a middle shelf, not the coldest back corner of your fridge. This keeps the berries chilled but not icy, to help with berry shelf life without ruining texture.
Raspberries hate excess moisture, so use the crisper drawer, only if you can lower raspberry humidity with a slightly open vent and a paper-towel-lined container.
For blueberries, skip the drawer and use breathable blueberry containers on a middle or upper shelf of your fridge.
Blackberries mould fast, so ensure your blackberries have good airflow. Store them in a shallow, vented container on a shelf, leaving a little space around the box.
Avoid stacking other foods on top of any berries, and don’t push them against the fridge walls, where condensation collects and shortens their life.
