My kefir grains arrived today! According to the enclosed instructions, I will need to put them in milk and change the milk every day for about 5 days. This should reactivate them and get them to start reproducing again.
The grains I ordered were cultivated in organic milk. I’ll be using them in goat milk for now, and once I get a healthy supply, I may experiment with other kinds of milk, or even with coconut milk/water/juice.
The first batch is in 1 cup of goat milk and is currently snuggled up next to my Kombucha.
UPDATE: I just read that I should not ferment different cultures near each other, as they may cross contaminate, so I’ll probably move the kefir back to the counter across the room from the refrigerator.
