I was updating the prefix on this- and realized I never gave an update on this. It was a great beer, and definitely a house favorite.

Is there anyway to get around adjusting the temps so much on this. As it is right now my fridge is dual purpose for kegs and fermentation?

Not really. Depending on the yeast you choose (I like German bock yeast), you have a pretty narrow temperature range. I think most lager yeast strains are in the 48-55 degree area.

You can lager at a higher or lower temperature, though. If your kegerator is at 40, for example, you can easily lager at that temp. To my mind, it won't be as "crisp" as a lager done just above freezing, but it's a decent compromise.

Oh okay, well this will be my first lager so I was/am a little confused. My fridge is set at 42 all the time, so could I lager this at that temp the whole time? By the way.... LOOOOVE the avatar

What would you do for an AG version of this, Yoop?

In early 2009, I made it like this:

12 lbs Pilsner (2 Row) Ger (2.0 SRM) Grain 92.31 %
8.0 oz Cara-Pils/Dextrine (2.0 SRM) Grain 3.85 %
4.0 oz Caramel/Crystal Malt - 80L (80.0 SRM) Grain 1.92 %
4.0 oz Munich Malt (9.0 SRM) Grain 1.92 %

And adjusted the hops to 25 IBUs. I was out of Mt. Hood, so I did this:

1.75 oz Hallertauer (60 min) Hops 23.8 IBU
0.15 oz Hallertauer [4.00 %] (15 min) Hops 1.0 IBU

I don't know if it was the same or not- I can't remember now, and my notes from 2006 (when I made the extract recipe) are lacking a bit! But they were both very good!

so, you raise to room temp, then step -5 deg / day from that? So, 65, 60, 55, 50....35?

No, I did a diacetyl rest first. Then racked the beer, and put it back at 55 degrees and then started dropping the temperature until I was lagering at 34 degrees.
