Hi there. I am in my fourth day of rehydrating dried milk kefir. I don't know when it is ready to consume. Today I thought it was starting to be ready but it tasted very sour and a bit like a cross between sour milk and cheese. I'm not sure. It also wasn't very thick. Can it take longer than this? I'm changing and discarding the milk every day.

When it gets that sour and cheese-like, use more milk or less grains to help balance them. Don't worry about the thickness. The kefir should taste pleasant to you and that's when it should be okay to drink.
