Can Cherry Cola go bad?

Quick answer

Cherry cola does not spoil in a dangerous way, but it loses fizz and flavor. Unopened, it keeps best for several months past its printed date, and regular soda is generally safe to drink after the best-by date. Once opened, drink it within about three to four days and keep it tightly capped in the fridge.

Can cherry cola go bad?

Not in the way that milk does. Soda is mostly water, sweetener and flavorings, so it does not grow harmful bacteria easily. What changes is quality: the carbonation escapes, the flavor fades and the taste can turn flat or odd. The best-by date on the pack is a quality date, not a safety date. Chowhound, citing the USDA, notes that soda is safe to drink past its best-by date.

How long does it last?

State Typical best quality
Unopened regular cherry cola The USDA, as quoted by Chowhound, suggests about 9 months past the date for best flavor and fizz
Unopened diet cherry cola About 3 months per the same advice
Opened, capped, in the fridge Roughly 3 to 4 days for good fizz
Opened, room temperature Goes flat quickly, often within a day or two

These are general guidelines, not guarantees, and the maker’s date on the pack is the reference.

What are signs it has gone bad?

  • Little or no fizz, and a flat taste.
  • Off or sour smell.
  • Color change, cloudiness or floating particles.
  • A rusty or bulging can, or a damaged plastic bottle.

If anything looks or smells wrong, throw it out.

How should you store cherry cola?

  • Keep unopened cans and bottles in a cool, dry place away from sunlight.
  • Avoid garages, cars and other places with big temperature swings. Heat can also affect plastic bottles.
  • Refrigerate after opening and screw the cap on tightly.

Can you drink old cherry cola?

If it is unopened, undamaged and smells and tastes normal, it is generally fine, just possibly flatter or weaker in flavor. If it has been opened and left out for days, the main risk is a bad taste, and floating bits or mold mean it should go.

People also ask

Is it safe to drink cherry cola after the expiration date?

If unopened and stored well, generally yes; the date is about quality. Discard it if it smells off or the container is damaged.

How long does opened cherry cola last?

About three to four days in the fridge with the cap on before it loses most of its fizz.

Does diet cherry cola expire sooner?

Diet soda is generally best within about three months, per USDA advice quoted by Chowhound.
