A big brown ale is not a fashionable seasonal offering for a craft brewery and for that reason Bison deserves kudos for doing one. There is nothing flashy or verbose about this beer, it doesn't try to wow you with incredible feats of palate bruising bitterness, cloying sweetness or wine strength booziness - it's actually quite understated. It belies its 'imperial' stature convincingly, it's quaffable and could easily be mistaken for a multi-pint session beer. Simplicity is too often overlooked in our modern world of extreme and niche craft beers, but not apparently by Bison - this is the definition of solid.
