Cold crash= low carb

pms67 · Dec 24, 2017

I saw Bigbanana on YouTube mentioning this and itÃ¢â¬â¢s something IÃ¢â¬â¢ve noticed with my last two or three brews, every time IÃ¢â¬â¢ve cold crashed it has produced a low carbed brew, at first I thought I had undercarbed but I was using the same sugar amounts as before.
Has anyone else noticed this? Does crashing kill off so much yeast that I need to up the priming amount?
Anyone else noticed this?
Cheers Ã°Å¸âÂ

I find it takes longer to carb up but gets there in the end.

I thought this thread was about the Atkins diet!

Much the same.

OP - what temp are you crashing at and for how long?

+1 on that

Never had any issue with cold crashing, do it all the time.

Yes, I've had undercabonation after cold crashes. Most eventually get there but some don't, with the same amount of priming sugar. I now tend to leave it no longer than 48hrs before bottling.

I had the same worry first couple of times I did it, then I realised that it just takes much longer to carb up. Once I relearned patience haven't had one not fully carb eventually. At the extreme a lager that has been at 0C for eight weeks will take a good six weeks to fully carbonate at room temperature.

Batch prime your beer and use this calculator: https://www.brewersfriend.com/beer-priming-calculator/

It gives a guide on fizziness of beer styles.

Just bottled an Imperial Pilsner which had been cold crashed to 1C for four days. I added 3.2g table sugar to each bottle as per calculator. But for the temp in the calculator i put 18C as this is what the brew finished fermenting at, is this the correct temp to add or should i of put 1C?

Yes, 18C is right.
