OK, I have to admit, when I made this recipe, it didn’t come out very well, but I blame that on the crazy rollercoaster of temperatures and pressures that I subjected it to. It’s based off a recipe from Beer and Brewing, and their recipes have brought me great results in the past.

What happened here was I figured I would ferment it at 70 degrees, and 15 PSI pressure. It’s a lager yeast in this version, and that would get me something drinkable, arguably with lager character, in a short amount of time.

At that temp, WLP833 became a krausen moster! In no time flat, I had wort blowing out of my spunding valve. I then crashed it to 50 degrees to get it to slow down. There were a couple of iterations of warming it up and bringing it back down again, I was really worried that the spunding valve was going to clog, and then the fermenter would explode. I managed to avoid that, but the finished beer is just murky and I think it really can use some time to settle out at lager temps.

Then, to add insult to injury, I charged it with pressure in the keg, and I usually leave it unconnected from the CO2 for a day, and then see if the keg held pressure, just to make sure I don’t have a leak. Well, I forgot to check and connect the CO2 again, so my beer was flat.

In any case, when / if I brew it again, or even after it lagers for awhile, I’ll update this post. Here’s the recipe, take it or leave it 🙂
