This morning I checked on my kefir and it had this purple layer on top I have never seen before. consistency-wise It's a bit thiner/more watery than the rest, like when the milk separates slightly during fermentation. It doesn't smell off.

For context, these grains have been going for ~10 years. Lately production has been taking a bit longer (~5 days for a litre), but I put it down to the weather getting cooler (I'm in the southern hemisphere).
