Whole Milk and Kefir questions

[Guest guest]

Remind me:

How long can I typically keep whole milk 'fresh' in the fridge?

When it turns, how is it best used?

I made my first batch of kefir with the Body Ecology starter this

week. after about 20 hrs on the counter, it was still 'runny.' In the

fridge, though, it seems pretty nice.

Is this normal? (no thickness without cooling?)

Also, the cream has risen on the kefir. I've seen this in 7-Stars

Yogurt, I guess it's to be expected (?)

thanks
