You're right, and I mean this nicely, that the rest of us know something you don't. That something is right here (and is my usual guidelines, that can be altered any way you wish for the recipe at hand):
Wheats/ pale ales/ anything I want dry: 150-152
Hoppy IPAs/ sharp porters (kinda bitey/ grain-bitter): 152-153/4
Big IPAs/ IIPAs/ stouts/ many specialty beers (which for me are often dark): 154-156
Generally, light, crisp, drinkable mouthfeel is a lower temperature. Some use 149 but that's out of my comfort zone, mostly influenced by a lack of thermometer trust. Chewy, filling stouts (Yooper's Oatmeal Stout is fantastic here) are mashed higher- 155, 156, something like that. If I want a higher apparent malt:hop ratio from an IPA I'll mash a degree or two higher. I don't have empirical evidence that this works, but to my tastes mouthfeel has a large effect on perceived bitterness (thicker= less bitter). Kyle
