Imperial Rhino Stout 2011

Teaser of the Label
I think it’s about time to post my first recipe on the site.  To kick things off I’m going to start with one of the biggest beers I’ve brewed to date, the 2011 version of Imperial Rhino Stout!

The name derives from the second beer brewed way back in 08 at a brew on premise which I called Rhino Stout. It was a nice oatmeal stout that unfortunately caught to some type of infection that gave it a metallic vinegar taste.

Cold Brew Coffee
This will be the second time I’ve brewed a stout under the name Imperial Rhino Stout but the two could not be more different. The 2010 beer was the 6th beer I ever brewed and conditioned so long that by the time I opened my first bottle I have brewed 21 more beers (about 6 months).  At this time I was still using pure Mr Beer so the recipe contained no steeped grains (thought it did use WLP001). Regardless of this after 6 months it was incredible (yes you can brew great beer with Mr Beer – I’ll post the recipe at the bottom).  I enjoyed the last bottle of the 10 version while waxing my 2010 Holiday Beer and have been planning the next version since.

I decided for the 2011 version I would hearken back to its roots and make an imperial version of an oatmeal stout.  I should note that the only I use the term Imperial is when it applies to a stout, everything else will be referred to as a double.  Given the fact that it will contain flaked oats it will require a partial mash.  I'm also going to loop in the coffee notes I got in the 2010 version using a cold brewed coffee extract at flame out and again at kegging. Essentially a cross between Founders Breakfast Stout and Surly Darkness
