Expiration & Storage Tips
When does lemon juice expire?
Unopened commercial bottles of lemon juice stored in a pantry typically stay fresh until the date printed on the bottle, usually around 12-18 months. Once opened, the juice should be refrigerated and consumed within 2 weeks for optimal freshness. If you've frozen lemon juice, it can last up to 4-6 months in a deep freezer. Homemade fresh lemon juice doesn't contain preservatives, so its shelf life is shorter, lasting refrigerated for only about 2-3 days.
How do you tell if lemon juice is bad?
Spoiled lemon juice will undergo changes in scent, color and umami or taste; it may develop a more intense, off-putting smell instead of its citrusy freshness. You might also see a color change to a darker, murkier yellow, and a change in taste as it turns more bitter. Mold development is a definitive sign of spoilage, especially in homemade juice.
Tips for storing lemon juice to extend shelf life
• To maximize the shelf life of lemon juice, store in a cool, dark place like the pantry before opening.
• Once opened, refrigerate the juice to prevent the warmth and moisture of a kitchen counter from accelerating spoilage.
• Opt for a squeeze bottle design for your store-bought lemon juice, as it limits oxygen exposure which can speed up spoilage.
• Fresh-squeezed lemon juice can be stored in ice cube trays in the freezer for long term storage. The cubes are great for instant flavor addition in drinks and food recipes.
• Avoid using containers with metal lids as the acidity of lemon juice can corrode them over time. Plastic or glass containers are preferable.
