ferment pressure

[Johno]

Hi Guys, Is it true that an increase in brew pressure allows us to ferment at higher temperatures and therefore faster times. Say 1.5 atmospheres
if so why?

I've read that, and I often transfer from my primary to a keg before fermentation is complete. The beer carbonates as it finishes fermenting, which is convenient, and I let the temp rise to ambient. The temp rise is intended to finish the beer more quickly: here's a link to a discussion of an accelerated fermentation process for lagers: http://brulosophy.com/methods/lager-method/

I have no idea if pressurization plays a part.
