Here’s the quick scoop: you can usually buy kefir in the dairy aisle of larger supermarkets, at health food stores, and from online grocery retailers. In the UK, examples mentioned in current sources include Waitrose, Sainsbury’s, Tesco, Asda, Holland & Barrett, Real Foods, and some Polish/Eastern European shops.

Where to look

  • Dairy section or refrigerated yogurt drinks.
  • International aisle in some supermarkets.
  • Health food stores and specialty grocers.
  • Online grocery delivery sites.

What to buy

  • Milk kefir if you want the classic tangy drink.
  • Water kefir if you want a dairy-free fermented option.
  • Kefir grains or starter culture if you plan to make it at home.

Practical tip

If your store stocks only a few brands, look for names like The Collective, Bio-tiful Dairy, or Lifeway on shelf listings and grocery sites. Availability varies a lot by region and store size, so a quick call or online search for your local branch can save time.

One simple route

  1. Check the refrigerated yogurt section at your nearest supermarket.
  2. Search the store’s website for “kefir.”
  3. Try a health food shop or specialty deli if the supermarket is out.
  4. Order online if you want a wider selection.
