See, I'm still not sure about wheat beers.
Classic for a hefe is 50% wheat, 50% Pils. But, it's also classic to decoct to develop some melanoidins, which darkens the beer and brings out some maltiness.
So, what happens if you sub in Maris Otter (at its heart, "maltier" than Pils malt) for the Pils, but don't decoct? Or, you only decoct for a short period? Does that work, too?
For a light *American* wheat, I'd stay away.... for a hefe, I probably would, too. For a dunkelweizen or a weizenbock (is there a difference?), I'm thinking Maris Otter would be a nice choice.
