Hey Meaders,

with the really low temps through this latest polar vortex blast, I set some jugs out to cool before drinking. surprisingly, what I thought was done-and-ready-to-drink mead further separated significantly.

the clarity didn't change that much; the flavor didn't change that much; BUT the smoothness (mouthfeel?) was significant; and it did have less "yeastiness" to it. win win win.

so what do I have? some questions on cold crashing for one thing.

- can a cold crash alone be used to prepare mead for bottling?

- what is principle factor in cold crashing, is the yeast "freezing to death" or does liquid density change suspension traits?

- what temps constitute "cold" in cold crash? my fridge cleary ain't cold enough as I had crashed these at the 40 deg.

- how long can a cold crash take? my mead was outside with temps near 0 deg for a few nights.

- will a cold crash separate the liquid further, rendering alcohol from it?

Thanks People for any advice, input, discussion.

Density is the reason. Won't change alcohol unless you freeze distill it. Cold is what you make it. Colder = more clarity.
