Mardi Bock

Brewed: 01/23/2021   Kegged: 02/05/2021

MardiBock.jpgSo, my homebrewing friend "Doc" invited me over to brew on Groundhogs Day. 

When I asked my wife (aka The SheppyBrew Beer Model) what I should brew. Her response was "A Mardi Gras Beer". Lent was coming up in about a month, so that seemed like a good one.

But what is a Mardi Gras beer?

Upon research and reflection, we agreed that it had to be a Bock-style beer.

I remember J. Wilson, the homebrewer and columnist who back in 2011 decided to follow the tradition of 17th century monks of Neudeck ob der Au outside Munich, Germany, developed the rich-and-malty beer to sustain them during Lenten fasts, the traditional 46-day lead-up to Easter.

Here is an article about the Lenten journey he took: My Faith: What I learned from my 46-day beer-only fast

He also wrote a book: Diary of a Part-Time Monk . 

And his blog on the project was Diary of a Part-time Monk

Anyway, J. Wilson picked (and the 17th century monks) picked dopplebock as their chosen style. I didn't want to go quite that big, so I went with a Dunkles Bock.

I had just brewed "PBR", so I had harvested lager yeast to help with the fermentation. And, of course, In the SheppyBrew 2018 Year-End Brewing Stats article, I said I would like to do more new recipes and more lagers in 2019. 

So, I came up with a recipe. 

I decided to keep the color and OG on the lighter side of the style. I decided to keep the bitterness a bit higher in the range just because I don't like overly sweet beers.

The resulting recipe is below.

The beer turned out fantastic. One of the beers that both the BrewMaster and Beer Model enjoyed. 

Batch 2 was ready for 2021 Lent.

Picked up ingredients Monday. Brewing today or tomorrow.

Brew day with Brew Model went pretty good. We measured low on pre-boil gravity and added .5 lbs to compensate. Then, ended up about that many gravity points high on the OG. Not sure what made the pre-boil gravity measurement low, especially with both of us checking. Anyway ... the wort is in the fermentor and the yeast is pitched.

Tilt says 1.066 at 56. Cooling set to 52. A little bubbling. Signs of fermentation just starting.
01/25/2021 esheppy
Tilt says 1.060 at 53. Raising controller to 53.
01/26/2021 esheppy
Tilt says 1.053 at 53F. Typical lager bubbling. Will probably leave at 53 today.
01/27/2021 esheppy
Tilt says 1.034 at 54. Raising controller to 54.
01/28/2021 esheppy
Early ... 1.024 @55F Still bubbling. I'm expecting fermentation will be done in the next couple of days. Set the anvil temp to 55. Later in day ... 1.019.
01/29/2021 esheppy
Mid-day ... 1.017 @59. Not much bubbling. Will turn off temperature control either tonight or tomorrow. Took a sample. Nice flavor. A little sweet. Hoping for another couple of gravity points. Color is a little lighter than the picture from last year.
01/30/2021 esheppy
1.017 @60. Unplugged cooling system.
02/02/2021 esheppy
Tilt has read 1.017 for 4 days now. 66 degrees today. I am ready to keg at any time. I actually have a keg free, but need to clean it. At this point ... the beer seems to be 6.9%ABV with an attenuation of 75%. Mardi Gras starts in 14 days. Will I be able to refrain from drinking before then? We'll see.
02/05/2021 esheppy
Kegged today. Awesome flavor. Beautiful color, but it looks a little lighter than the picture from before. Its clarity is even really good going into the keg. Mardi gras starts in 11 days. Should be ready in plenty of time.
02/07/2021 esheppy
Took a sample. Almost no carbonation. Turned up psi to 20. Great flavor. Really really good. Reminds me of my award winning maibock. 😎
02/10/2021 esheppy
Took another sample. Carbonation about right, so I turned down psi some. Gorgeous and delicious beer.
02/27/2021 esheppy
Been drinking. Delicious. Lots of Munich malt flavor. Clarity is great now. Hope this lasts until at least Easter.
03/06/2021 esheppy
Gorgeous beer. Delicious.
03/15/2021 esheppy
Very clear. Beautiful red color. Nice bready Munich malt flavor. Enough hop bitterness to balance sweetness. Will this last until Easter? Not sure, but considering it is still 20 days away, probably not.
03/26/2021 esheppy
04/04/2021 esheppy
Well... This beer lasted to Easter. 🐣 yum. Of the beers I had today, this was my favorite. Nice clear dark red. Bready. Malty. Balanced. So Guuud.
04/06/2021 esheppy
The keg finally kicked today. Suck a great beer! I'm proud that I was able to make it last all the way through Lent.
