Cold Crashing techniques
I give fermentation 4-5 days at 63°F, then bump up the temp to 70-72°F for maybe another 3 days. Then I crash to 33°F for 3-5 days until the beer clears.

Long cold crash for an ale. Benefit or harm?
What you're doing is lagering the beer, so it would have the same benefits it has for a lager beer. Beer deteriorates much more slowly at cold temperatures.
The only possible problem I know of is ...

Fermentation not over?Cold crash or not?
It looks like the fermentation is complete, as the specific gravity has essentially stabilized. However, I'd leave it at 20C for another week at least to let the yeast clean up before cold-crashing. ...

Can I cold crash if I'll be bottle-conditioning?
Once you have cold crashed there will still be enough yeast to carb up your beer, given enough time.
I suggest leaving your beers in primary for your usual amount of time, but racking to secondary ...

cold crashing question
I cold crash (and fine with gelatin) at 30F for two or three days before kegging. I have found that 30F for two days clears my beer better than weeks at 38F in my refrigerator.

How long should I maintain cold crash temperature for Witbier?
To really answer your question, a couple of days more or less will not make a difference.
Actually, you shouldn't cold crash witbier. It is also bottled with its yeast. At serving time, you then make ...

Yes, you have it. Normally you cold crash at the end of fermentation, before bottling. And a word of warning...if it was still outgassing heavily when you bottled it, it's likely fermentation wasn't ...

Cold Crashing Mead. Need help with details
Most of the time mead makers don't cold crash. Just let it sit and it will clear over time. If you want to speed it along look into wine fining agents.

How long should I maintain cold crash temperature for Witbier?
Yes, you can keep the temperature for several days, no problem.
The only problem that can cause you is to clarify too much and lose the turbidity that witbier needs.
Glad to be able to help!

Cold crashing and risk of oxidation
This is a valid way to do it.
There will be a slight amount of air and therefore oxygen sucked in, but not enough that I would worry about it.

Would an extended time cold crash at 10°C work or not?
It won't hurt anything for sure. It will work about how you'd expect, actually, your beer will clear up quicker than at room temperature but not as fast as if you could get it down to 35 F or wherever ...

Cold crash with airlock or not
There's no need for an airlock. By the time you get to cold crashing, fermentation is done so the need for an airlock is gone. I seal the fermenter using a solid stopper before cold crashing.

"Debugging" a bitter DDH NEIPA

You don't really need to rack to secondary. Just cold crash in your primary fermenter, and then be very careful not to suck up any yeast from the bottom when you transfer to your bottling bucket.

How long does clarification take given a refrigerator temperature level cold crash?
For cold crashing we go from tank temp to 4C in about a day, that is due to the limitations of our cooling plates and chillers. If we could drop a tank from 18-20C to 1C in 12H I would take that. ~1....
