I've brewed this beer probably 6 times and it always comes out great! Brewed again today at my wife's urging for "that delicious dark beer"!
Nottingham, s04, and conan are all great with this recipe. I've also used all sorts of different hops with good success including summit, centennial, cascade, crystal, and finally apollo today.
I've added the malto at 15mins, flame out, and once not at all, always with good success.
Can't go wrong with this beer, it makes all the commercial porters taste thin and one dimensional! I'm ruined!
