Gut Cultures started the way many good things do: a family friend passed along a small jar of kefir grains, we gave it a go, and haven't stopped since. Now we spend our days growing and sharing starter grains with people who want to make their own kefir at home.

Kefir is one of the most probiotic-rich foods you can get – more so than yogurt, and often more effective than probiotic supplements. Making it yourself means you're getting the real thing – live and active cultures, in their purest, most potent form.

We’re not a big operation, and we like it that way. Every culture we send out has been cared for in small batches, and we're always happy to answer questions if you're just getting started.
