Incredibly easy to use, the starter culture can create a new batch of water kefir every 24-48 hours. Water kefir makes a fantastic non-dairy alternative to milk kefir and can be flavored to make a range of delicious beverages, or as an ingredient in many recipes. Your family will love it!

Very good

Posted   by Robyn from Marina del Rey, California
This was simple. I had kefir in 24 hours. I just put a jar of whole milk and one package of grains in a mason jar and put paper towel over the lid and waited. It’s fun.

no luck

I just couldn't get these to go. I'm not sure if it was the sugar I used (I tried a few) or if it was the bottle I was putting it in, or some other variable.

Not as easy as it seems

I wanted to love this product and hoped it would help my stomach issues. Unfortunately, I didn't feel any different. Honestly, I don't even know if I made it correctly.

Maybe I got damaged grains

Posted   by Sarah from Salinas, California

I often share my excess grains with friends and family, but I recently had none to give when my mom asked for some. I got my starter grains from this exact kit, purchased off the company’s website, and they have been going strong for years. I’ve also started a couple kits for friends. I figured I’d order some here (save a few bucks) and get them hydrated and ready for my mom. I have not gotten any fermentation after 5 batches. I hydrated them according to instructions and use only spring water. I’ve also been using a heating mat to maintain water temp. I did not have this issue with my grains in the past, so I can’t understand the problem. Maybe I got a bad batch, but I’m bummed I wasted my time and $$$, and my mom still doesn’t have what she needs to produce her own water kefir.
