  • Full of living cultures

    Commercial kefir is made using freeze-dried bacteria of isolated strains. We only use real, living cultures (SCOBY) for maximum gut goodness.

  • Proudly Small-Batch

    We handmake our kefir with care, using traditional methods in small batches & glass jars at our East Sussex fermentary and kitchen.

  • Organic, grass-fed origins

    Our milk comes straight from our next-door neighbours, Hook & Sons Farm, Sussex. Organic, Regenerative & grass-fed happy cows!

  • 100% Recyclable approach

    We use recyclable packaging wherever possible, and always bottle in glass (no plastics!). For London deliveries we even collect your bottles.

Feed your gut, fuel your body!

  • Supports a healthy immune system
  • Restores & enhances your gut health
  • Helps alleviate digestive issues such as IBS and colitis
  • Relieves skin issues such as eczema & psoriasis
  • Rich in calcium for strong bones
