Funny I read this after I brewed something similar last night. I'm new at home brewing (5 batches) and am sticking with smaller volume (2 gal) for fear of messing up and being pressured to drink 5 gallons of bad beer (old college moral virtue: never waste beer).
My recipe for 2 gallons, I'm calling "Smokey Churchill Porter":
8 oz chocolate malt (350 SRM)
8 oz caramel malt (80 SRM)
0.7 oz lapsang souchong
3.5 lb dark liquid extract
1 oz Willamette boil 60 min.
.25 tsp Irish Moss boil 10 min.
Safale-04 dry ale yeast
SG - 1.062
Like others, the wort ended smelling splendid: piney, smokey, chocolate and caramel. I was afraid of the volume of tea, since it is potent stuff. But so far it seems .7 oz was just about right - time will tell.
Wikipedia says that lapsang suchong was Sir Winston Churchill's tea of choice...if so, this beer with be his beer of choice 1 degree of seperation http://en.wikipedia.org/wiki/Lapsang_souchong
I am new, but I'll be back...
