Partial Extract Oatmeal Stout-




I found this recipe online, it looks pretty good, but I'm not entirely sure how it will turn out.

"Black Dwarf Imperial Oatmeal Stout

A heavy thick brew. The flavor lasts for upwards of a minute. (hops and dark grains followed by full malt and grain flavor, finishing with molasses. Bit alcoholic tasting when warm.
Ingredients:

    * 3.3 pounds, liquid Northwestern amber
    * 3.3 pounds, liquid Northwestern dark
    * 3 pounds, pale 2 row
    * 2 pounds, dark crystal (90 Lovibond)
    * 2 pounds, flaked barley
    * 1-1/2 pounds, steel cut oats
    * 1 pound, wheat malt
    * 3 cups, roasted barley
    * 1-3/4 cups, black patent
    * 1-1/2 cups, molasses
    * 5 ounces, malto dextrin
    * 1 stick, brewer's licorice
    * 1-1/2 ounces, Northern Brewers leaf hops
    * 1/2 ounce, Mt. Hood pellets
    * 2 ounces ,3.0 alpha Hallertau
    * 1 quart+, starter---Wyeast Irish Ale

OG: 1.090 FG: 1.032
Primary Ferment: 7 days"

This recipe is for about 8 gallons of beer.



 

I am wary of any recipe that measures grains with cups and not in ounces.

But other than that the recipe looks intriguing, give it a try and let us know how it turns out.

 

I think the measurements in cups is a little odd too, but not a reason to not brew it.   

With an 8 gallon 1.090 brew, I'd pitch a much larger starter than just 1 quart.   Check out http://www.mrmalty.com/calc/calc.html for proper pitching rates. 

The recipes states to leave in primary for 7 days.  I think you should let your hydrometer tell you when its done fermenting and I'd still leave it in the primary for another week or 2.

Along with a proper pitching rate, you're going to need to aerate/oxygenate that beer well to get the attenuation you want.  I think 1.032 is too high and leaves you with 62% attenuation.   I usually hit 70-73% with the Wyeast Irish Ale.

 

I did the A to Z brown contained in the book extreme brewing, writtne by the guy who owns dogfish head brewery.  Good book, crappy recipe.  The molasses was overpowering.  I'm not sure if you've ever had molasses before, but I can assure you a little goes a very long way.



 

The beer turned out really good! It has a good smooth mouth feel, combined with a roasty barely/oatmeal taste, with nice hoppy finish. It's bottle conditioned for about 3 weeks, I'm really curious how it will taste given some more time.

I left out the licorice and malto.
