By far, the most common thing to do with excess grains is to give them to family and friends.

But after a while they will all either have their own overgrown collections of water kefir grains or they just aren’t interested.

This is somewhat akin to growing zucchini, pretty soon no one wants your extras. And that’s why I have included a few more ideas!

  1. Offer the grains on your local Facebook groups! There are buy, sell, trade groups for most areas now. Even my tiny little town has a few!
  2. Store extra grains in your fridge or freezer. They will store well in an airtight container for up to 3 weeks in the refrigerator and 2-3 months in your freezer.
  3. You can add your bonus grains to smoothies for a nutritional boost.
  4. Don’t want to eat them? Your chickens might! The beneficial bacteria is great for everyone!
  5. No chickens at your house? Mine either. So you can feed the extra kefir grains to your plants instead. Just mix into your soil and the grains work as an organic fertilizer to keep your garden happy.
  6. Too many grains for your plants? Add them to your compost bin!
