This is the same site I got my milk kefir from. The strainers come in handy, I ordered extra strainers from them because you have to use it daily, so I cycle the used ones through the dish washer.
I also ordered a 2nd batch of grains as a backup in case the first batch dies on you. The key is once you start drinking kefir, that you keep drinking it every day. If a batch dies on you from either warm temperature or water exposure, then you have to order another batch online, then spend 5 days activating the grains once you get them in the mail.
Not sure which one is better, but milk is what I use and its great.
1. Ferment the grains with organic whole milk for 24 hours. After 24 hours, you will have a jar of both grains and Kefir.
2. Strain out the grains and put Kefir in a new glass jar, and the grains in another glass jar. The website has videos on youtube illustrating this process.
*While my grains are still in the strainer, I pour fresh milk over them to clean them off before I put them in a empty jar.
3. Put organic milk into new jar with the strained grains to start another batch. Stir grains with a wood spoon.
4. I set aside the Kefir and let it ferment for another 24 hours. I put mine uncovered in the fridge. This continues to eliminate sugars and lactose.
I’m up to a 2 batch rotation. I drink 1 in the morning and 1 at night. I always doing my straining at night time because I have more free time. Straining 2 jars and cleaning up after yourself takes about 15-20 minutes.
You can get wooden spoons & glass jars at Target or Walmart.
