Mardi Bock (archive)

This is the archive page for Mardi Bock. For the current recipe .. see Mardi Bock.

This was a beer originally brewed to enjoy during Lent in 2019.

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.

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.

Moving to secondary to make room to ferment a new beer today. 1.016 fg. Needs to clear up a bunch. Harvesting yeast. 
02/10/2019 esheppy
Sample tested great. 
02/17/2019 esheppy
Took another sample. Lots of Munich malt flavor. Clearing up nicely. 
02/18/2019 esheppy
Putting into cold garage to cool for gelatin. 
02/19/2019 esheppy
Added 1 tsp unflavored gelatin to 3/4 cup water heated to 160. Put that into carboy. Will let sit in cold garage until weekend. 
02/23/2019 esheppy
Kegging today. Nice clarity, but I'm not sure gelatin did any more than a simple cold crash would have. Beautiful dark amber color. Lots of rich Munich malts flavor. 
02/24/2019 esheppy
Had outside last night with a 30psi shot of gas. This morning, put leg in beer fridge and added another shot of gas. 
03/05/2019 esheppy
First pint is delicious. ?? More balanced than most bocks. 
03/05/2019 esheppy
First pint was not as crystal clear as I thought it would be. Second pint is already getting better. Still not sure the gelatin quite lived up to what I expected. 
03/08/2019 esheppy
Really nice color. Really nice clarity. Really nice flavor. 
03/22/2019 esheppy
Delicious bready Munich flavor. 
03/30/2019 esheppy
Yummy beer. Carbonation is perfect. Color and clarity great. 
05/05/2019 esheppy
I think this is almost gone. Crystal clear. Intense Munich malt. Such a great beer.
