Rocktoberfest Lager (archive)

  Seasonal beer to drink during the baseball playoffs ... hopefully while the Rockies are going to another world series.  The first one was a dark, balanced, almost sweet brew with a decent ABV.  It was sort of a dunkle munich style ale.  2010 is closer to a traditional Ocktoberfest lager without any Mr. Beer ingredients.  Am planning to brew this every August to be ready around October.

08/15/2012 esheppy
Updated recipe. Will probably buy ingredients tomorrow. 
08/16/2012 esheppy
Got my ingredients. 
08/19/2012 Brew Day esheppy
Brewed it up. Everything went well. Mash through church. 90 minute boil. Used my pre-chiller to help cool into the 60's then, racked to my 5 gallon carboy and left it in ice for an hour or two. Then, I racked that into two Mr. Beer fermentors. Pitched both at about 52 degrees. 
08/20/2012 esheppy
By the end of day 1, but fermentors are going. Both are at 50. 
08/22/2012 esheppy
Rutt running a bit higher in the 55 or 56 range. Tuke is right at 52. Both are fermenting away.
08/25/2012 esheppy
Rutt at about 54. Tuke still right about 52. Both still have kraussen. 
08/26/2012 esheppy
Kraussen starting to fall. Think I will let both fermentors warm up to get yeast cleanup going. Both still below 55. 09/05/2012 esheppy
Was going to keg tonight, but there was an issue with the beer-out poppet valve on the keg. Did take a sample. Both at 1.012 which puts the ABV right at 6%. Perfect IMHO. Flavor also wonderful.
09/15/2012 esheppy
Finally kegged this up. Pressurized to 30 psi and then placed in conditioning cooler. Will probably start drinking in about a month. 
09/30/2012 esheppy
Have had in keggerator for a couple of days. Tried sample today. No carbonation, but wonderful munich malt flavor. Pressurized to 15psi. Will try another sample tomorrow I think during Monday night football. 
11/08/2012 esheppy
Finished the keg. I am a little sad to see it go, but I am really looking forward to drinking "Eric the Awful".

Will most likely brew this up over the upcoming weekend. 
09/11/2011 Brew Day esheppy
Brewed it up. Everything went pretty well. 
09/12/2011 esheppy
Both are at a good temperature. Tuke is visually fermenting away. Rutt is lagging, but looks like he should be going by the end of the day.
09/12/2011 esheppy
Now both are at 52 and chugging away.
09/18/2011 esheppy
Well, Tuke seems pretty much done. I'll let his temperature rise to finish up. Rutt still seems to be working away. I'll keep his temp low. I probably had a bit more variation in temperature than I really wanted in both coolers. They certainly stayed in the right range, but they went back and forth between 52 and 56 depending on what phase the ice bottles were in. 
09/21/2011 Samples esheppy
Took a couple of samples. Tuke was right at 1.012 and Rutt was about 1.014. Average out to 1.013 means about 6% ABV and 77 ADF. Both samples taste absolutely fantastic. 
10/04/2011 Kegged esheppy
Kegged these up with about 4.75oz table sugar. Set the psi to 15 or so to seal the keg up. OG ended up right at 1.011 for both fermenters. Sample tasted great. Exactly what I think a flat Oktoberfest should taste like. 
10/06/2011 esheppy
Looks like I made the same mistake with this as I did with Buckwheat ... I primed as if I had 5.5 gallons instead of the 4.8 gallons in the keg. Am going to off-gas this a little bit every day. 
10/20/2011 esheppy
Have had the keg in the keggerator for a few days. Tried a draft tonight. Might have have been a bit undercarbed so I pressured up the CO2 to 15psi. Will leave it for a few days. The beer tasted perfect to me. The rich malty munich was balanced perfectly with hop bitterness. Loved the flavor. 
10/30/2011 esheppy
Tastes great. Not much head retention. What is up with that? 
12/29/2011 esheppy
Head retention has improved greatly since the last note. Been drinking and enjoying it from the keg. Need to beer gun some bottles so I can empty the keg and get my black IPA into the keggerator. 
01/01/2012 beer gun esheppy
Bottled up 12 with the beer gun. Bottling didn't go all that well. Too much foam. Think I wasted about a beer and a half getting all 12 filled. Keg is close to gone. Did not chill the gun and tubing as I should have. Oh well. Had one that was just wonderful. Very yummy. 
01/07/2012 esheppy
Killed the keg. Glad I have those few bottles fun beer gun last week. 
03/15/2012 esheppy
Tried one of the bottles. Great marzen flavor. Wish it was a bit better carbonated. 
04/22/2012 esheppy
Very disappointed with carbonation. Flavor is great. 
06/10/2012 esheppy
Used a couple bottles to brine a chicken. Carbonation was not as bad on the taste I had. Still not great but better than last bottle I tired of this. For the most part I have been only using this beer for cooking, but maybe I should drink some too.

Brewing Notes:
01/16/2011 Brewing Day esheppy

Brewed it up. My mash efficiency was not even as good as it used to be. Ended up with 1.056 OG, but did not fill up all the way. Need to get a temperature strip for the Mr. Beer bottling "bucket". It will be hard to monitor the temp until I do.
01/17/2011
Got a temp strip today. Put it on when I got home. Temp right at 48/50 which is a bit cooler than I would like it to be, but there is a good start at kraussen and there is some activity.
01/22/2011
Pretty steady rise up to 55 or 56. Still going well. Keeping temp right there with one frozen water bottle. Brewing lagers in winter is so nice!
01/24/2011
Kraussen pretty much gone.Going to let temp rise for cleanup. 55 right now. Will let it go where it wants now.delete
01/29/2011 esheppy
Up to about 64. Took out of cooler.
02/10/2011 Bottled esheppy
Bottled today. Used the big bottling bucket. Have to say, I'm not wild about using this for little batches. Of course my last double batch wasn't that great either. I guess I just have to get used to it. Only got 18 12oz plus 1 liter bottle. Sample tasted great, though. The Munich malt came through beautifully.
02/24/2011 into the cooler esheppy
Put these into the conditioning cooler with an ice bottle. This batch seems ridiculously small. Will certainly have to brew a double batch for fall.
03/12/2011 esheppy
Had the LB. Lots of floaties in this beer, but Soooooo good.
04/12/2011 esheppy
Had O, which was probably the 2nd to LB. Very clear until almost the very bottom when some floaties came up. Still a wonderful tasting beer. Hopefully the rest don't have so much trub, though.
04/17/2011
Found 2 from last batch.Crystal clear and absolutely wonderful munich malt flavor.
05/13/2011 esheppy
Really like the balance with this beer.

Comments 08/21/2010 Brewing Day esheppy
My second all-grain brew. Everything went well, but I would really like to improve my mash efficiency. Should be a nice beer, though. I am looking forward to it.
08/22/2010
This morning, the ambient temp of the cooler is 48. The strip on the keg reads 52. Nice layer of krausen on top. Sort of weird to see that in such a cold environment. So far, so good on the lager temperatures.
08/27/2010
The strip has still consistently been right at 50/52. Looks like krausen and activity may be slowing down, so would like to let the temp rise to 55 or so. Just going to not change bottles until the temp starts to come up.
09/02/2010
Ambient up to 59. Strip up to 58. Seems that this fermentation has been about perfect (at least as far as temperature goes). I'll let it warm up to clean up any diacetyl, and then ideally bottle at the end of the weekend.
09/07/2010 Bottled esheppy
Yesterday, I bottled this batch up. Good attenuation. Sample tasted great and really thought the clarity was wonderful. Really looking forward to drinking this beer in a month or so.delete
09/26/2010 esheppy
Had the lb and compared it to a sam adams octoberfest. Really like my beer! Not as clear as I would like, and head retention could use some help, but taste is perfect imho. Mine is better than sams's. delete
10/09/2010 esheppy
Had one. Clarity has improved considerably. The rich malty flavor is still there. Wonderful color. Nice balance. Great beer.
10/22/2010
Had one last night. Wonderful beer. This one had very little head.
10/31/2010
Had a liter to take the picture for this beer. The picture doesn't do the color justice. Really wonderful taste. Great Beer. Good head this time.
11/28/2010 esheppy
Had a liter while watching football. Man, this is a yummy beer!
12/09/2010 esheppy
Had another. This is the best Ocktoberfest style lager I have ever had.
