How to Tell if Hemp Seeds are Still Fresh
Identifying signs of rancidity and oxidation in your hemp seeds.
Hemp seeds stay fresh for about 6–9 months when stored in a cool, dark pantry.
Hemp seeds are nutritional powerhouses, but because they contain high levels of healthy fats, they are susceptible to oxidation. When exposed to heat, light, and air, these oils can break down, leading to a process known as rancidity. While rancid hemp seeds aren't typically dangerous to consume in small amounts, they lose their pleasant nutty flavor and can develop an unpleasant, soapy taste or odor. Proper storage is the key to maintaining that fresh, earthy profile for your smoothies and salads.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
