I've been seeing the process " cold crashing" mentioned a lot here and am unclear about what it means. Tried to search but couldn't get an understanding of its purpose. I am currently dry hopping a Citra pale ale. I forgot to add the irish moss to help clear it. When I added the hops for dry hopping I checked the the beer temp and it was @ approx 72* and the SG was at 1.012. When /how and do I need to "cold crash" this beer? I need to double check the SG on Friday as this will be the 5th day of dry hopping and I plan on bottling it on Sunday so any suggestion on how to proceed would be welcomed.Thanks in advance!!!

Cold crashing is for clearing the beer once fermentation is complete. Stick the fermenting container in a fridge for 1-7 days (or longer) and the yeast will settle out of suspension. I rarely resort to cold crashing myself. but it can be very useful...

At the end of the ferment the yeast normally clump up and settle to the bottom of the fermenter. This normally takes some time so if you are kegging the beer you need to wait for the yeast to settle or you draw off beer with yeast making the beer cloudy. By chilling the beer in the fermenter the yeast settle out much faster and you can transfer to the keg sooner without the yeast.

In short!

It can be either done in the secondary or in the keg!
It's a process of clearing the beer up by using coldness:-) a fridge or outside non-freezing winter temps. It allows the beer to become uncloudy or less cloudy.
Done before keg'n or bottling. I typically allow mine to set in keg for 2-3 weeks before I drink.

It can also help reduce the sediment in your bottles.

To cold crash, just put the fermenter in the fridge. I've heard of people leaving it in there for 24 hours up to a week. It's like a really short lager, but it's purpose is not to cold condition, just to precipitate out yeast and other particles.

So it is done more when kegging than bottling? My beer has been in my primary for what will be 2 wks on Sunday. I'm guessing the SG will be good come Sunday as the FG the kit was targeting is 1.021. If my SG is still the same as the last I'm understanding that it is done fermenting and ready to be racked to the bottling bucket for priming and bottling. Am I on the right track timeline wise? The kit OG was supposed to be 1.075 and I had 1.064. I'm not sure why it was low but think it was a lack of proper blending of the water I topped up to when transferred to the fermenter.

You can cold crash with bottling. Just bring it back to 65-70, then rack to bottling bucket with primer and bottle away.

With a beer with an OG that high I would wait longer before bottling. I think you would get better beer that way. The only rush is so you can drink poor beer sooner instead of giving it more time to mature and drink it when it is better.
