"White Knuckle Ale" is a Double India Pale Ale. That's right, twice the malt and twice the hops in one 14-barrel batch! It is named in honor of the exciting bike trail on Mt. Tam. If you are a "hophead," this one's forYOU! It's fat, chewy and resiny and pungent. Pour into a wide-mouthed glass and get ready toRIP! 8.0% alcohol by volume.
