2nd All Grain Homebrew: Vienna Lager

Second All Grain Brew.

After some of the *ahem* hiccups with my first all grain brew (cream ale 1/24/10) I went it at a week later 1/31/2010 and brewed my first lager (vienna lager). I upgraded from the seemingly ineffectual pex filter in my mash tun.
This time I used the often lauded stainless steel braid, and after struggling with the pliers and the finger-cuff-like action I switched to a vice clamp with a milking action.

Given my 20 point miss the first time around, I used a grain bill with a slightly higher than style estimated OG. The estimated OG was 1.058. I had no problems with the lautering. I also collected the correct amount of wort this time. Previously I has messed up the volumes somehow. I realize now, that I should really do an actual job of determining the volumes in my kettle and bucket. I am still educated guessing it. So knowing the volumes for real would be smart. I'll get out the measuring stick soon.

For the single infusion mash I aimed for 60 minutes @ 152F. I think it might have ended up starting closer to 150F and then falling during the rest. The pre-boil OG was 1.060. The post boil after I added the water to get to my estimated 5.25 gallons was 1.050. I was 8 points off, but now within the style guidelines. I was quite happy with this improvement.

I aerated via aquarium pump for about an hour and pitched a 1 liter stepped to 3 liter starter of Wyeast Octoberfest 2633. I pitched at 52 degrees.
