How Long Does Lemon Juice Last? (Does It Go Bad)

Lemon juice is prized for adding acid and citrus to many recipes and should be a staple in your kitchen. It can be used in everything from a savory dinner marinade to sweet desserts baked for the entire family.

But what if your lemon juice is past the expiration date? Is it safe to use? Does lemon juice and lemon juice concentrate go bad?

You will find the answers to all your questions in this article so you know if your old bottle of lemon juice is safe to consume and if it’s time to get a new jug.

We will cover fresh squeezed lemon juice, premade lemon juice, as well as lemon juice concentrate.

Let’s get right to it!

How To Tell When Lemon Juice Goes Bad

Lemon juice offers a long shelf life and when stored properly will likely be used up before it goes bad. But what happens when you find a bottle of lemon juice you completely forgot about and need to know if it’s safe to use?

Lemon juice can spoil and there are a number of factors that contribute to how quickly that happens.

Your first clue will be the best by date on your bottle. While that date does NOT mean it has spoiled as soon as the date has come and gone, it is a good indication of how old your lemon juice is.

Time and storage conditions are the two primary factors that dictate if your lemon juice has gone bad or not.

The more recent your lemon juice was squeezed as well as proper storage ups the chances that your lemon juice is still good considerably.

This goes for fresh squeezed lemon juice as well as bottled or even lemon juice concentrate.

Fresh Squeezed Lemon Juice Shelf Life

Who doesn’t love a glass of ice cold lemon juice? Or maybe you are adding fresh squeezed juice to up the flavor of your recipe. No matter why you made fresh squeezed lemon juice, it is important to know how long it will stay good so you don’t waste any.

When stored in the refrigerator, fresh lemon juice will last up to 4 days. If frozen, fresh lemon juice will last up to 1 month.

Store Bought Lemon Juice Shelf Life

Most store bought lemon juice comes with a “best by” date. This date is not an expiration date, but is instead the manufacturers recommended use date for maximum flavor.

When properly sealed and stored, refrigerated store bought lemon juice will remain good for a week or two past the “best by” date.

But lemon juice can also be found in unrefrigerated form as well. This type of store bought lemon juice offers a longer shelf life and will remain good for up to 1 year when unopened, and up to 6 months after being opened.

Lemon Juice Concentrate Shelf Life

Frozen, unopened lemon juice concentrate has a long shelf life. The “best by” date is yet again, a manufacturers recommendation for retaining the best flavor. Properly frozen concentrate can be used for up to 2 months after the “best by” date.

Lemon juice concentrate that comes refrigerated or even room temperature has a shorter shelf life and can generally be used up to 1 week past the “best by” date.

Prepared lemon juice made from frozen concentrate will stay good in the refrigerator for 1 week. While it can be frozen after being prepared, I have found lemon juice from frozen concentrate does not retain as much flavor when refrozen so I recommend using it up within a week to avoid needing to refreeze it.

Signs Lemon Juice Has Gone Bad

If you are still unsure if your lemon juice is safe to consume or add to a recipe then there are a handful of things to check that will tell you if your lemon juice has gone bad.

Check How it Smells

When lemon juice spoils it is because bad bacteria has taken up residence and this lead to the smell changing.

Good lemon juice will smell of citrus with hints of sweet while bad lemon juice will smell stronger and tangier.

Look at the Color

When lemon juice is fresh it has a light yellow color but when it goes bad, lemon juice takes on a much darker color.

Bad lemon juice will also be much cloudier than fresh so pour some into a glass and check to see if your lemon juice is still good.

Do a Mold Check

When bacteria begins to grow in your lemon juice it can grown to the point there is visible mold.

If you see any signs of mold in your lemon juice you know it is no longer safe to use.

Taste Test

If your lemon juice is the right color and there are no signs of mold but you are still unsure if it is safe to use, do a taste test.

Just a small sip will let you know for sure if your lemon juice is good to go. If it tastes like you expect then your lemon juice is good, but if you pick up any hint of rancid flavor then your lemon juice should not be used.
