How Long Fresh Juice Stays Good in Your Refrigerator

Fresh juice lasts three to five days in the refrigerator, depending on how it was made and how you store it

Freshly squeezed juice — the kind you make at home or buy from a juice bar — keeps for about three days at 40°F or colder. Store-bought cold-pressed juice lasts longer, usually five to seven days, because the high-pressure processing kills more bacteria than a home juicer does. Pasteurized juice from the grocery shelf keeps much longer unopened (weeks or months, depending on the brand), but once you open it, treat it like fresh juice: three to five days.

The difference comes down to what's still alive in the bottle. Fresh juice contains living yeast and bacteria that slowly ferment the juice, turning it sour and creating gas that can pop the lid. Pasteurization heats the juice just enough to kill most of these microbes, but not all — so opened pasteurized juice still spoils faster than the sealed bottle did. Cold-pressing uses extreme pressure instead of heat, killing bacteria without cooking the juice, which is why it lasts longer than home-squeezed but not as long as pasteurized.

Key Takeaways

• Freshly squeezed juice keeps for three days in the refrigerator; cold-pressed lasts five to seven days; opened pasteurized juice lasts three to five days.
• Store juice in a sealed glass or food-grade plastic bottle on the coldest shelf of your refrigerator, not on the door where temperature fluctuates.
• Juice begins to lose vitamins and flavor within hours of being squeezed, so drink it as soon as you can for the best taste and nutrition.
• If juice smells sour, tastes fizzy, or has visible mold or separation that won't mix back in, throw it out — fermentation has begun.
• Freezing fresh juice extends its life to three months, though texture and some nutrients change slightly after thawing.

Why fresh juice spoils faster than other drinks

Juice is mostly water and sugar, which sounds like it should last forever — but it's also packed with natural acids, enzymes, and nutrients that microbes find irresistible. The moment you break the skin of a citrus fruit or crush an apple, you expose the juice to air and bacteria. Those microbes start eating the sugars and producing acid and gas as waste, which is why old juice tastes sour and fizzy.

Oxygen is the other enemy. Fresh juice oxidizes quickly, which breaks down vitamins (especially vitamin C) and changes the flavor and color. A glass of fresh orange juice left on the counter for two hours will taste noticeably duller than one you drink right away. In the refrigerator, oxidation slows down but doesn't stop, which is why even properly stored juice loses quality after a few days.

The right way to store juice in your refrigerator

Use a sealed glass bottle or food-grade plastic container — never leave juice in an open pitcher or cup. Glass is better than plastic because it doesn't absorb flavors or odors and doesn't leach chemicals over time, but clean plastic works fine for a few days. Make sure the lid seals tightly; a loose cap lets air in and speeds up spoilage.

Store the bottle on the coldest shelf of your refrigerator, usually the bottom shelf or the back of the middle shelf. Never store juice on the door, even though it looks convenient. The door is the warmest part of the refrigerator because it opens and closes constantly, letting warm air in. Temperature swings cause juice to spoil faster and can cause separation or fermentation to start.

If you buy juice in bulk, keep unopened bottles in the coldest part of the fridge and move one to a more accessible spot only when you open it. This keeps the backup bottles at a steady, cold temperature. Once you open a bottle, use it within the timeframe for that type of juice — don't let it sit half-empty for a week hoping to finish it later.

Signs that juice has gone bad

Spoiled juice usually announces itself clearly. Smell it first: if it smells sour, vinegary, or "off" in any way, don't drink it. A sour smell means fermentation has started, and the juice is no longer safe. Look for visible mold — any fuzzy growth, dark spots, or cloudiness that wasn't there before means bacteria or mold has colonized the bottle.

Taste and texture matter too. If the juice tastes fizzy or tingly on your tongue, fermentation is underway and you should discard it. Some separation is normal — pulp settles to the bottom — but if you shake the bottle and the liquid doesn't mix back to a uniform color, or if there's a layer of sludge that won't budge, the juice has begun to break down. When in doubt, throw it out. Drinking fermented juice won't poison you, but it can cause stomach upset.

Freezing juice to extend its life

If you have more juice than you can drink in three to five days, freeze it to keep it for up to three months. Pour juice into ice cube trays for portion-sized cubes, or fill freezer bags or containers, leaving a little headspace because juice expands as it freezes. Label the container with the type of juice and the date you froze it.

Thawed juice won't taste exactly like fresh juice — the texture can be slightly thinner, and some of the bright flavor fades — but it's still drinkable and nutritious. Thaw it in the refrigerator overnight, not on the counter. Use thawed juice within one day; don't refreeze it. Frozen juice works well in smoothies, cooking, or baking where the slight change in texture doesn't matter.

How to make fresh juice last longer at home

If you juice at home, the fastest way to extend shelf life is to juice into a clean, sealed bottle and refrigerate immediately — don't leave it sitting on the counter while you clean up. The longer juice sits at room temperature, the more oxidation and bacterial growth happens. Some people add a squeeze of lemon or lime juice to fresh juice, which lowers the pH and slows spoilage slightly, but this only buys you a day or so.

Invest in a cold-press juicer if you juice regularly and want juice that lasts longer. Cold-press juicers use hydraulic pressure instead of spinning blades, which generates less heat and oxidation. The juice lasts five to seven days instead of three. They're more expensive upfront and slower to use, but if you make juice several times a week, the longer shelf life means less waste.

Frequently Asked Questions

Can I drink juice that's been in the fridge for a week?

It depends on the type. Unopened pasteurized juice from the store may still be safe, but opened fresh or cold-pressed juice should not be kept longer than five to seven days. Smell and taste it first — if it smells sour or tastes fizzy, discard it. When in doubt, throw it out.

Why does my fresh juice separate into layers?

Separation is normal — pulp and fiber are heavier than liquid and sink to the bottom. Shake the bottle to mix it back together. If the layers won't mix no matter how hard you shake, or if there's a thick sludge at the bottom, fermentation has begun and you should discard the juice.

Does juice go bad faster in plastic or glass bottles?

Glass is slightly better because it doesn't absorb odors or flavors and doesn't leach chemicals, but the difference is small — usually just a day or two. The bigger factor is how well the lid seals and how cold your refrigerator is. A tightly sealed plastic bottle in a cold fridge will keep juice just as long as glass.

Can I drink juice that tastes a little fizzy?

A slight fizz means fermentation has started, and the juice is no longer at its best. It won't poison you, but it can cause stomach upset or bloating. If you're sensitive to fermented foods, discard it. If you don't mind the taste and have a strong stomach, it's your choice — but fresher juice is always safer.

How do I know if frozen juice is still good after thawing?

Thawed juice should smell fresh and taste normal, though slightly less bright than when it was first frozen. If it smells sour or off, or if it was frozen longer than three months, discard it. Use thawed juice within one day and don't refreeze it.
