Imperial Rhino Stout 2011

Recommended Posts

Back at the end of May I finally got around to my Imperial Rhino Stout

The 2010 version was the 6th beer I ever brewed and conditioned so long that by the time I opened my first bottle I had brewed 21 more (about 6 months)

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.

I enjoyed the last bottle of the 10 version while waxing my 2010 Holiday Beer and have been planning the next version since.

The 2011 version will harken back to its roots and be an imperial oatmeal stout. This will require me to perform a partial mash, figures crossed.

I'm also going to loop in the coffee notes I got in the 2010 version using cold brewed coffee at flame out and during secondary transfer.

I'm aiming for a cross between Founders Breakfast Stout and Surly Darkness

I'm planning on sparging with 7 qts at 170F

I tried several methods for filtering but in the end ran it through the filter in my wife's coffee pot

The Mash

I took my second partial mash really seriously. The first go around I had some heat loss at the end and ending up swinging too far the other way. The beer turned out fine by I still wanted a better way to control the mash. Then I discovered the Oven Method online.

Put all my grain in my big bag

Put the grain and water into my kettle along with salts and chemicals, stir and check temperature then put the kettle in the oven for an hour

You might notice the lean, this is cause by the tennis ball underneath I use to swirl
