I'm planning to brew a stout and was thinking of adding pumpkin pie spices into the wort.
I've been looking at various threads but having a hard time coming up with consensus. My plan is to brew a base stout batch (extract) and throw the spices in around flameout.
Can you recommend amounts of spices? Either individual - cinnamon, nutmeg, etc - or just from a pumpkin spice mix.
