River rapids are rated by a numeral system. Class V is the most difficult level rapid that can be negotiated.
This non-traditional beer is an Oatmeal Stout, Milk Stout and an Imperial Stout all in one. With a complex flavor profile ranging from coffee to chocolate, the sweetness is complemented with Chinook and Cascade hops to produce an extraordinary finish. But at 8.5% ABV, don't let the smooth taste fool you; this beer is like the Kern at high water - "Not for the Timid".
