NOTES:

Coal Porter is a scaled version of the well-liked recipe I brewed at the now-defunct Black Rock Microbrewery & Restaurant in Wilkes-Barre, PA.

Relatively light-bodied - in fact, everything is on the low end of the BJCP category standards for Robust Porter - it's a very satisfying session Porter which continues to be well-received. Just this past weekend (April 25, 2009), five gallons was consumed in about two hours.

All-grain versions use Fawcett's malts, as that's the English maltster I prefer.

A simple, single-infusion mash can be used, so long as well-modified English or American pale malts are used. I batch-sparge; if you fly-sparge, or have efficiencies different than mine, don't forget to keep that in mind in your version.

This also lends itself well to extract/steep techniques. Simply substitute 6 lbs of malt extract syrup for the pale malt and steep the specialty grains. I've used Briess Gold LME in the past, and it's been exactly the same flavor.

I shoot for 5.5 gallons in the fermenter, because I generally lose a half-gallon in trub and syphon loss.

For serving, avoid over-carbonation. I don't like to go above 2 volumes on draught or 2.5 in bottles. Over-carbonation accentuates the bitterness of the hops and roasted malts to the detriment of the beer.

Cheers!

THIS JUST IN: You can now order this recipe as a kit from Brewmaster's Warehouse, as all-grain or extract/steep.

For extract/steep are hops both thrown in at beginning of boil? Sorry only 5th batch for me. Also your extras, yeastex and whirlfloc thrown in 15 minutes before end if boil?

Thanks this looks awesome

Love the name...

Frog - the 60-minute hops (Amarillo) are added when the boil commences. The Willamette are added when the heat is switched off. Additives are indeed added at the 45 minute mark, otherwise known as "15 minutes left". Tip: The additives are not really necessary. I add them out of habit more than anything. This beer is dark enough that clarity really isn't an issue, so the Whirlfloc can be skipped. And an 11-gram packet of dry yeast doesn't need the Yeastex nutrient.

Dunright - Thanks! :mug:

Cheers,

Bob

Brewing this soon, with some substitutions, namely hops. I only have Cascade and EKG on hand, can I just sub them for the Amarillo and Willamette ? I know it won't be the same beer, but the LHBS is out of both.

Bob 11-12-2010 10:21 AM

Sure. Sub away.

I'm not a real stickler for hops varieties in my recipes. As long as the finishing hops are close, I'm happy. YMMV, of course.

Cheers,

Bob

Heating up the strike water right now :D

EDIT: Everything is done, an unenventful brew session if there ever was one. Only two issues arose: I used too much sparge water and ended up with 7 gallons into the boil kettle instead of 6.5, wich meant a longer boil and I broke my thermometer when I was storing it for future use. Ended up with 5.8 gallons of 1.047 wort into the carboy, so I'd say it was a success.

Good job, you! :D

I gotta brew more of this meself...

This is a weird beer. The krausen had pretty much dropped Thursday when I left (brown goop settling down, etc.). I'm back home today and it has taken near epic proportions: the foam (white again?) is over 6 inches high ! I'm guessing it's the US-05 chilling near the top but it's a beautiful sight :D

EDIT: Seven days after pitching, I'm about an inch away from needing a blowoff. This is crazy. US-05 likes the Coal Porter something fierce. Ambiant is around 60F !
