I made my first batch of kefir with a paper "breathable" towel over the top of a glass container. If I want to store the output in refrigerator, do I have to make it "breathable", or normally close it with solid lid?

If you'll drink it quickly, you can store it with an airtight lid, but this will make it "fizzy". Personally, I'd store it with a breathable lid to avoid carbonating it, and possibly causing it to explode. There's still live/active cultures, even when you remove the kefir grains.

Edit: quickly, as in a day or so
