I am wondering if anyone can help me with an odd looking precipitate that I had in a secondary fermentor.
I made an IPA, that was transferred from 2 6.5-gal glass carboys (primary fermentation) to 2 5-gal glass secondaries.
I dry hopped with pellets.
I placed the secondary in my beer cellar (where lately the temps probably dipped below 45 F).
There is a layer of sediment/yeast in the bottom of the carboys, but what was floating in suspension was somewhat stringy/snot looking. I guess the carboy is smooth inside, but oustide it is not perfectly smooth. The outside of the carboy is somewhat ornate, raised in square patterns, that typical of other carboys I have seen (if this makes sense). The snotty suspension was hanging out inside the carboy mostly in the same pattern of the square ribbing outside. What is weirder is when I knocked the carboys gently the snot slowed dropped to the bottom of the carboy. After a few minutes, the beer appeared quite clear, and there was a less dense snotty layer about the dense sediment layer in the bottom of the carboy.
Maybe its not that odd, but maybe I hadn't observed this before since my 6.5 gal fermentors are "jacketed" with styrofam, and these two secondaries are unjacketed (I do cover them with trash bags so no light hits the beer).
Any guesses? Same proteins responsible for chill haze? I did not get aggressive with the siphons at any stage, but I guess there could be some hot or cold break left.
Very odd patterns to the precip.
