Doing a vintage, long-aged RIS, with 25% brown malt. I normally use Fawcett's at 35-45 L, and like it quite a bit (just kegged an awesome Taddy with some) but we are out. We do carry Swaen, including their brown malt at 80L, but I don't know how much qualitatively different these are from one another, beyond just color. Anyone with experience on this one?
