Hello everyone, and thanks for any answers (Hopfully that's the correct place to publish the question).
Is there any significance to the fermentor volume concerning the amount of wort in it?
For example, if I have 20lt of wort in a 50lt fermentor, would I have better\worser results of fermentation due to the space left in the fermentor?
Thanks in advance.

G'day Timos, the last couple of batches I've done I put 10-11 litres of wort into a 30 litre fermenter with no I'll effects, and every thing seemed to go as normal. The fermentation did go a bit faster but that was due to using a full pkt of yeast on a half batch.

So generally, there is no known issue regarding this subject?
If that so, well, thank you very much.

You'll soon find that the homebrew world is filled with horrendous science and downright superstition.
A lot of people will claim the giant headspace will lead to oxygenation of your beer. But with the massive C02 creation the yeast is causing, how would any oxygen get in there?! You've got positive pressure in your fermenter (as evidence by the bubbling) and no harm will come.

And not to mention co2 is heavier than air so it will create a protective barrier anyway. I'm pretty sure that there are some breweries that do open fermentation, so I guess they rely on that principle.iijakii wrote:You'll soon find that the homebrew world is filled with horrendous science and downright superstition.

all is true, but the rule of thumb is to leave about 25% of the volume as head space. so for a 20L batch you want a 25L fermenter.
I use 30L plastic barrels and usually get in 23-25L of wort to end up with 19-21L of finished beer.
But, having said that, i am a true believer in not overthinking homebrewing. after all, it's not rocket science

Cube:
fermenter: Sourdough Spelt Ale, Classic Lambic, Oud Brune, Barrel Aged Belgian Dubbel
Kegs: Bob's Black IPA, Blanc Blond, Soda...

I'm using a 34L carboy and a 25L plastic foodgrade fermentors for 20L wort.
I do like the carboy more, as it's scratch free and no oxygen diffusion, altough the carboy's harder to sanitize and handle.
Both do the job well, but I was wondering whether or not the head space is crucial.
