Like a lot of items on our grocery lists, nuts won’t stay the freshest in the thin plastic bag you buy them in. Nuts can last for one or two months in your pantry, but they need to be kept away from heat and light. They spoil quickly due to oxidation, which can make them turn soft or taste bitter. To prevent food waste, transfer your almonds, cashews, peanuts or favorite nut mix to an airtight food storage container. Plastic is fine, but I’m trying to reduce the potential for microplastics to leach into my food. Luckily, I found the perfect glass jars for storing my favorite nuts, and they’re on sale.

Weck Tulip Jars, 2-pack

~~$33~~ $24 at Amazon

The Weck Tulip Jars come in a 2-pack that’s discounted to $12 apiece. Designed for home canning, the glass lid is completely airtight, with a rubber gasket and stainless steel clips that help keep nuts fresh. The thick glass jars also have a wide mouth that makes it easy to scoop out what you need without making a mess on your countertop. “They’re solid, easy to use, easy to clean and beautiful!” one customer wrote. Another person added that the dishwasher-safe jars are “high-quality and leakproof, have a tight seal and are stylish!”

In addition to keeping your nuts fresh, tasty and mold-free, the beautiful jars condense the clutter in your kitchen, meaning no more crumpled plastic bags. “[The jars] save room in my fridge, so I will be buying more in different sizes and tossing some of my other bulky containers,” one reviewer wrote. “They are more than worth the money,” another buyer said. “Will be buying more soon!”

In addition to using them for food storage, some shoppers say the jars are the perfect size for housing a sourdough starter. However, one shopper advised removing the gasket and metal clips to allow “pressure to escape when fermenting a sourdough starter.” “There is plenty of room for your starter to grow and be happy in this 1-liter jar,” they added. It’s also great for making a big iced coffee or storing your coffee beans.

Stop storing your food in plastic—these airtight Wake up Jars keep your nuts fresh and healthy, and you can grab the set on sale. If the wide-mouth, rounded canning jars aren’t quite your style, I’ve found a few more glass nut storage containers below.
