How Long Do Lemons Last?

How long do lemons last at room temperature?

Whole lemons last about 1 week at room temperature when stored in a cool spot away from direct sunlight. The thick protective peel keeps the flesh fresh for several days, but moisture gradually evaporates through the peel, causing lemons to shrivel and become harder to juice over time. Counter storage works fine for lemons you'll use within a week; longer storage requires refrigeration. Store lemons in a bowl or basket with air circulation rather than a sealed container, which traps moisture and accelerates mold growth. Keep them away from bananas, apples, and other ethylene-producing fruits, since the gas accelerates lemon ripening and softening. Lemons stored above ovens or in hot windows shrivel within 3-4 days.

How long do lemons last in the fridge?

Refrigerated lemons last 3-4 weeks in the crisper drawer at high humidity. The cold temperature slows the moisture evaporation that causes shriveling at room temperature. Store lemons in a sealed plastic bag in the crisper drawer for the longest shelf life; the bag traps humidity, which lemons need to stay plump and juicy. Some people store lemons in a glass jar of water in the fridge, which keeps them fresh for up to 3 months; change the water weekly. Cut lemons last 3-4 days in the fridge in airtight containers; lay them cut-side down on a small plate covered with plastic wrap to prevent the cut surfaces from drying out. Refrigerator temperatures slow the natural enzymatic browning of cut citrus.

Can you freeze lemons?

Yes, lemons freeze well in several forms for 3-4 months. Whole lemons can be frozen for use as ice cubes in drinks; the freezing changes the texture so they're not suitable for fresh use after thawing but work for cooking and beverages. Lemon zest freezes excellently in small airtight containers; the volatile oils that give lemon zest its bright flavor are preserved by freezing. Lemon juice freezes in ice cube trays for portioned use later; pop the cubes out once frozen and store in freezer bags. Lemon slices freeze on a baking sheet first to prevent sticking, then transfer to freezer bags for use in drinks or cooking. Lemon halves can be frozen for use as flavor agents in broths and stocks.

How do you tell if lemons have gone bad?

Spoiled lemons show several clear warning signs. The texture becomes soft and yields easily when pressed rather than firm with slight give; very soft lemons have started decomposing inside even if the outside looks normal. Significantly wrinkled or shriveled peel indicates moisture loss; these lemons are past prime and may have very little juice left, though small amounts of shriveling are tolerable for cooking use. Visible mold (white, green, blue, or black fuzzy patches, often appearing first at the stem end) means immediate disposal. Brown or black spots on the peel that extend deep into the flesh signal rot. A fermented or off smell beyond the normal sharp citrus aroma signals internal spoilage. Slimy or sticky peel surfaces indicate bacterial growth.
