With all the summer stuff going on, I too, have put my kefir in the fridge. I haven't touched it in a week. When I strain it it will have separated so I will have to give it a good stir before staining. Yeah, it does get expensive when feeding it to the chickens in large amounts. Mine are out on pasture in a fence that I move when the green stuff is getting worn looking. I like to feed more kefir in the winter when the chickens have no access to fresh and living food. I have also stopped sprouting because they have greens growing in the pasture. Will sprout again probably in November....Keir is still going but I am not drinking as much. I usually like 2 week kefir, but it is aging more before I drink it.Besides, Sangria with pineapple and watermelon has replaced it on these hot summer days after work, when I go out and sit with the flock and unwind!!
So yeah, I would keep it going, just let it slow down. I believe that Kombucha and kefir have different organisms for fermentation and IMO, more is better in this case.
I love kefir with maple syrup. I eat smoothies too, but when I use maple syrup, it goes down way to easy!
