Can't seem to find an actual definition of this term. What is cold crashing? How is it done and what is its purpose?

Thanks

Cold crashing is just dropping the temperature on your fermenter. After fermentation, it helps in clearing the beer. Proteins and yeast will drop out of it more at the lower temps.

Cold crashing is basically refrigerating your beer in order to clear it up. When you cold crash, it causes more yeast, proteins, etc... to drop to the bottom of the beer where so you can rack above it and have clearer beer goingn into the bottle or keg.

Putting the beer at standard refrigerator temps for a day or so makes a big difference.

A word about this, which needs to be kept in mind. The aforementioned facts are correct, but I want to point out that after cold crashing if you keep the beer very cold it essentially arrests the aging process. It doesn't completely stop but eeks along. I suggest allowing your beer time for proper aging before cold crashing.

The other option is to cold crash and then age it too. that's what I do.

Can you cold crash in primary or would it be best to only cold crash in secondary?
