I haven't posted anything in a while because nothing terribly exciting has been going on. Although today I'm patiently awaiting a FedEx package with two unique White Labs vials inside.
Poking around on the White Labs site last week I noticed the High Pressure lager yeast (WLP925) that's listed by them as a professional strain. According to their instructions, you can use this yeast to produce clean lagers by fermenting the whole time under 15psi. Primary for one week between 62F and 68F, secondary for 3-5 days at 35F. Of course I got all hot and bothered when I read this and set about scouring the internet to find out how to get my hands on it.
Even though it's a professional only strain according to White Labs, I found it for sale at Midwest. So it's on its way today. When I'm ready to do another lager, I'll build up a starter and ferment in a corny keg with a shortened dip tube. This will allow me to maintain the 15psi necessary and leave the yeast and trub behind in the keg when I rack to the secondary (serving keg).
I've heard that some of the mega brewers are able to turn lagers around faster by fermenting warmer under pressure. When yeast are in a pressurized environment they produce fewer esters. We'll see how this experiment goes. If this turns out to be "the one", it could be a game-changer.

Sounds interesting Tom, keep us posted.
I just got the White Labs tubes in the mail. They're standard WL tubes with labels and everything. No idea why it's not listed as a homebrew strain on their site - or why Midwest is the only shop that carries it. A bit of a mystery.
I'll definitely post on the results once I've brewed with it.
