Obsidian Stout, take #2

This is another rebrew of a Brewing Network, "Can You Brew it" beer.  I brewed my first take back in December 2011.  At the time I only thought it was an OK beer but my stout friends loved it.  Before the keg kicked I bought the commercial example and did a side by side.  The beer was dead on with the original. 

Last weekend I got the question from my wife, "When are you going to brew a beer for me?"  Not having the time at to formulate another recipe I pulled this one out for a rebrew.  I brewed it last Sunday with a hangover.  Which made me very detailed on following the recipe BTW. 

The only change is a bigger starter and a lower fermentation temperature, which you can see in the notes below.

  1. Thanks! I will put this on my agenda. I would like to brew this in the future. Does the Chinook give a lot of citrus/pine? I mean, is the beers character dominated by the Chinook?

  2. This is closer on the porter side of the flavor wheel...but I think the pine flavors did not dominate the beer. Think if it as a Pacific Northwest Style Stout.

    Yesterday I bought a 6 pack of the original and I will do a side by side once it is done.


Thanks for Commenting, Prost!
