Lemon juice adds zest to many recipes with its tart flavor. Instead of squeezing the juice from a fresh lemon every time you need it, you can store the juice to use it later. Fresh lemon juice does not contain preservatives like commercial lemon juice. Fresh lemon juice will last for two to four days in the refrigerator or up to four months in the freezer.

Wash the lemon with cool water to remove any dirt and debris. This will prevent you from contaminating the lemon when you slice it.
Place the lemon on a cutting board. Roll the lemon back and forth with the palm of your hand while pressing down firmly. This will break down the fibers so you can squeeze out more juice.
Place one-half of the lemon on a citrus juicer. Press it down to release the juice.
Pour the lemon juice into an airtight container. Store it in the refrigerator for two to four days.
Pour the lemon juice into ice cube trays if you want to freeze it. Once the lemon juice freezes, place the cubes into a zipper-sealed plastic bag. You can then thaw as much fresh lemon juice as you need.
