How Long Apple Cider Lasts in the Refrigerator

Unopened apple cider lasts 2 to 3 weeks in the refrigerator

Most store-bought apple cider will stay fresh for 2 to 3 weeks from the date you bring it home, as long as the bottle or jug remains sealed. The exact timeframe depends on how the cider was made and whether it was pasteurized—a heat treatment that kills bacteria and extends shelf life. Check the label on your bottle; pasteurized cider lasts longer than unpasteurized cider, which is sometimes sold at orchards or farmers markets.

The printed expiration or "best by" date on the label is your most reliable guide. Manufacturers set these dates based on testing, so follow that date rather than counting days from purchase. If you bought the cider and didn't check the date, look at it now—you may have less time than you think.

Key Takeaways

• Unopened pasteurized apple cider lasts 2 to 3 weeks in the refrigerator; unpasteurized cider lasts 1 to 2 weeks.
• Once you open the bottle, apple cider stays fresh for 5 to 7 days if you keep the cap on tightly between pours.
• The printed expiration date is more reliable than counting days, so check the label before you buy.
• Apple cider that smells vinegary, tastes fizzy, or shows mold has fermented or spoiled and should be discarded.
• Freezing apple cider in ice cube trays or freezer bags extends its life to 8 to 12 months.

Opened apple cider lasts 5 to 7 days once the seal is broken

After you open the bottle, apple cider begins to oxidize and bacteria from the air can enter. Keep the cap on tightly between pours and store the jug in the coldest part of your refrigerator—usually the back of a shelf, not the door. The door is warmer because it opens and closes, so cider stored there will spoil faster.

If you notice the cider tastes slightly fizzy or has a vinegary smell after a few days, it is beginning to ferment. This happens naturally when wild yeast or bacteria convert the sugars in the cider. A little fizz is harmless if you like the taste, but if the smell is strong or unpleasant, or if you see mold floating in the jug, throw it out.

Pasteurized versus unpasteurized cider: the difference in storage time

Pasteurized cider has been heated to kill most bacteria, so it lasts longer—typically 2 to 3 weeks unopened. Most cider sold in supermarkets is pasteurized. You will see the word on the label, or you can assume it is pasteurized if it was made by a large commercial producer.

Unpasteurized cider has not been heat-treated, so it contains living bacteria and yeast. It lasts only 1 to 2 weeks unopened and may begin to ferment sooner, especially if stored in a warm spot. Unpasteurized cider is often sold at orchards, farmers markets, or small producers. The label will usually say "unpasteurized" or "raw," and some bottles carry a warning about raw juice.

Both types follow the same rules once opened: keep the cap on tight, store in the back of the fridge, and use within 5 to 7 days. The difference is mainly in how long you can keep an unopened bottle.

Signs that apple cider has gone bad

Smell is the first warning sign. Fresh apple cider smells sweet and slightly tart. If it smells vinegary, musty, or sour in a way that makes you hesitate, do not drink it. Trust your nose—it is detecting fermentation or mold growth.

Look for visible mold, which appears as white, gray, or brown specks floating in the cider or coating the inside of the bottle. If you see mold, discard the entire jug. Do not try to pour around it or strain it out; mold roots spread through liquid.

Taste is a last resort if you are unsure. A small sip of cider that tastes unusually fizzy, vinegary, or off-flavor has fermented. Spit it out and throw away the rest. Fermented cider is not dangerous in small amounts, but if the fermentation is advanced, it may contain enough alcohol or bacteria to upset your stomach.

How to store apple cider to keep it fresh longer

Keep unopened bottles on a refrigerator shelf, not on the door. The door is the warmest part of the fridge because it is exposed to room temperature every time you open it. A shelf in the back, especially the lower shelves, stays colder and more stable.

Once opened, cap the bottle tightly after each use. Oxygen and bacteria from the air speed up spoilage, so a loose or missing cap cuts shelf life in half. If the original cap is lost or damaged, transfer the cider to a clean jar with a tight-fitting lid.

Keep the temperature of your refrigerator at 40°F (4°C) or below. If your fridge is warmer than this, cider will spoil faster. You can check the temperature with an inexpensive refrigerator thermometer, which clips to a shelf.

Freezing apple cider extends storage to 8 to 12 months

Freezing is the best way to keep apple cider beyond a few weeks. Pour the cider into ice cube trays and freeze until solid, then pop the cubes into a freezer bag and label it with the date. Frozen cider cubes thaw quickly and work well in smoothies, baking, or heated drinks.

You can also freeze cider in freezer bags or rigid containers, but leave about an inch of headspace at the top—cider expands as it freezes and can burst a full container. Frozen apple cider stays safe to drink for 8 to 12 months, though the flavor may fade slightly over time.

Thaw frozen cider in the refrigerator overnight or at room temperature for a few hours. Once thawed, use it within 3 to 5 days, just as you would with fresh cider. Do not refreeze cider that has been thawed.

Frequently Asked Questions

Can I drink apple cider after the expiration date?

If the bottle is still sealed and has been refrigerated the whole time, it may be safe a few days past the date, but the flavor will decline. Once opened, follow the 5 to 7 day rule regardless of the printed date. When in doubt, smell and taste a small amount first.

Why does my apple cider taste fizzy?

Fizz means the cider is fermenting—natural yeasts are converting sugar into carbon dioxide and alcohol. A slight fizz is harmless and some people enjoy it. If the fizz is strong or the smell is unpleasant, the fermentation has gone too far and you should discard it.

Is it safe to drink unpasteurized apple cider?

Unpasteurized cider can contain harmful bacteria like E. coli or Salmonella, especially if the apples were not washed thoroughly. Healthy adults usually tolerate it, but pregnant people, young children, elderly people, and those with weakened immune systems should avoid it or heat it to 160°F before drinking.

Can I store apple cider in the freezer instead of the refrigerator?

Yes. Freezing stops all spoilage and keeps cider safe for 8 to 12 months. Thaw it in the refrigerator and use it within a few days, just as you would fresh cider. Freezing does not harm the nutritional value, though the flavor may soften slightly.

What should I do if I accidentally left apple cider on the counter overnight?

If it was sealed and the room was cool, it is probably fine—smell it first. If it was open or the room was warm, bacteria may have multiplied. When in doubt, throw it out. Do not taste it to check; a small amount of harmful bacteria will not change the flavor.
