How long does Calpis last unopened?

Calpis (sold as Calpico in North America) is a concentrate or ready-to-drink product based on fermented milk. Unopened, check the best-before date on the bottle. We could not find a manufacturer statement of total shelf life. Store unopened bottles in a cool, dry place away from sunlight.

How long does Calpis last after opening?

Refrigerate it: retailer listings for Calpico say to keep it refrigerated after opening and use it as soon as possible. We found no official number of days, so go by the instructions on your bottle. As a cautious rule, finish an opened bottle within a few weeks and discard it sooner if the smell or look changes.

How long does diluted Calpis keep?

The concentrate is meant to be mixed just before drinking. Mixed with water or milk, keep it covered in the fridge and drink it the same or next day. We found no official figure for this, so treat it as a conservative suggestion.

What about Calpis Water and Calpis Soda?

Ready-to-drink bottles and cans carry their own best-before date. Once opened, refrigerate and drink soon; soda goes flat.

Can you freeze Calpis?

We found no manufacturer guidance. Some people freeze it as ice, but we cannot give a time limit.

How can you tell Calpis has gone bad?

  • Off or rotten smell, or a sourness stronger than usual.
  • Mold, slime or fizzing in a non-carbonated bottle.
  • Bulging cap or leaking container.

When in doubt, throw it out.

How should you serve it?

Mix concentrate with water, soda water, milk or ice, to taste; follow the dilution on the bottle.
