Cold Crashing. Is it required?

[slantedbolt]

Is Cold crashing only for making the beer clearer?

 

[Revvy]

I'm confused, are you askign if Cold crashing is required to make clear beer, or if you are asking if cold crashing does ANYTHING ELSE besides making your beer clear.

If it's the former, then, NO Cold crashing isn't mandatory to making clear beer. I have no facility to cold crash, yet my beer is incredibly clear. Cold crashing is one of the many ways to clear beer.

If it's the latter, it also causes the yeast to go dormant.

I was asking if it did anything besides clearing the beer.

So if it makes the yeast go dormant, is it a good idea to always cold crash?

 

[slantedbolt]

the reason I ask is that my krausen has fallen finally and I am doing readings over the next couple days. So if the FG is constant, should I cold crash for an certain reason?

 

[osagedr]

Should cold-crashed beer always have yeast added at bottling? Or is there a "rule-of-thumb" on the length of time a beer is cold crashed after which it should have yeast added at bottling?

Sort of depends on what you are brewing and what you are trying to achieve.

 

[Marko73]

Yeast that goes dormant from cold crashing will 'wake up' after you add priming sugar and put it at 70 degrees to carb. If you are lagering, it is a different story. But if you are simply cold crashing, I am not sure I would add any further yeast.

Don't confuse going dormant with falling out of suspension. After cold crashing the idea is to rack from above the cake and only get yeast that is left in suspension. If you cold crash for too long (weeks), too much yeast may fall out of suspension making bottle carbonation difficult. Cold crashing for a few days causes the yeast to go dormant but not all fall out of suspension so carbonation is not a problem. Adding yeast or stirring up the cake after cold crashing defeats the purpose of doing it in the first place.

Thank you, this was the information I was looking for.

How you make clear beer without cold crash?

 

[BrewInspector]

Allowing enough time in primary that the yeast fall

Use of a high floc yeast.

Use of whirlfloc / Irish moss during the boil

Use of fining agents like gelatine (usually in the keg if not during cold crash)

Refrigeration after packaging in keg or bottles

TIME

Any combination of the above

Do beer will be carbonated if immediately storage to fridge after bottling?

 

[BrewInspector]

I think you are asking if the beer will be carbed if you put it in the fridge immediately after bottling.

NO

If you are bottling you need to keep them warm for the yeast to carbonate the beer. It would be too cold for the yeast to carbonate in the refrigerator.
Once you have satisfactorily carbed the beer (2-3 weeks or so) put them in the fridge. The longer the better (to a point)

And so I thought so I was confused by your previous post.
