The Impact of Increased Headspace During Fermentation

[Beer-lord]

An interesting Exbeeriment for those that are curious from Brulosophy.

I did read this article about headspace, and true to form, came away not quite convinced that there were any noticeable differences. Is it just me?

That's what I came away with as well.

I didn't get the "why" they were picking one over the other but it is interesting that this time around 8 of the 11 that picked out the different beer preferred the one with less headspace. Just interesting, that's all.

I've brewed 2.5G in a 6G bucket before and loved it. Could it have been better? I dunno. I do know that fermentation creates a TON of CO2 and fills headspace pretty quickly - that why airlocks and blow off tubes work.

SO what am I saying here? I dunno....

I heard Marshall (the Brulosophy guy) on a podcast from last week discussing this exact Exbeeriment and many on the show felt the same way.....that even 1/2 empty there's enough CO2 from a good yeast pitch to kick all the oxygen out the fermenter.
