I've been reading a huge HBD backlog (due to the 'phone strike, I've
been a tad busy, lately) this morning, and am surprised that no one
seems to have answered Gordon's question on cold breaks in HBD 221.
So, lacking either fear or good judgement, I'll rush on in ...

As I understand it, a "break" is large-scale flocculation, usually
of proteins, brought on by temperature change. The hot break occurs
during boil, and results in the sediments left behind with the hops
when racking from the boiler (assuming you cool the wort elsewhere).
The cold break results from the abrupt temperature drop of
force-cooling, and reputedly removes many nasties responsible for
chill haze and off-flavors.

If my understanding is flawed, I'm sure someone will set us straight
promptly! 8->}
