Mardi Bock

Brewed: 01/23/2021   Kegged: 02/23/2019

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.
