I don't think there could be any geometry effect at all, unless you were using an exceptionally tall and narrow fermenter.
Well, they are extremely worried about switching to cylindro-conicals in Belgium, due to the reduced ester profile from the taller tanks versus 1 to 1 height : width square fermenters. Check out BLAM for more info on this. CO2 inhibition from pressure is also scientifically documented in the commercial brewing world.
From the paper:
"If pressure is applied above 1 bar a formation of higher esters is visible. This
can also happen in tall fermentation vessels due to pressure. On the
Isn't this saying the opposite about pressure & esters.
Also, when homebrewing, won't using an airlock vs a non-sealed lid add pressure?
contrary, open or shallow vessels will give lower ester levels."
