My Bugs (aka Milk Grains) are good! They are making Milk Kefir like crazy. I am using 2% milk and sit the jar next to a salt lamp I have sitting on my counter. It's just enough warmth that I am at curds and whey within 2 full days, so at 1.5 days, if the kefir is getting thick, I move it to the refrigerator where the bugs finish their job. My Ninja blender makes a healthy drink with mixed berries & kefir and a bit of ice. I started with this years ago trying to get my whole digestive and elimination system in order. Then I got busy and forgot about making this wonderful morning drink. Now, it's time to get back on track.
