I decided to pick up a six pack of Sierra Nevada's fall offering, a brown ale called Tumbler.
Pours with a thick off-white head that stays around for quite a while. Dark amber to light brown and fairly clear when held to the light.
Roasty malt nose with some raisin. There's a little grassy hop but not too much.
Raisin and molasses with some biscuit in the back end. A fair amount of bitterness for a brown (it's definitely an American variant).
Medium body with a little astringency. Not entirely unpleasant. Not as thick as some browns I've had (notably Ithaca's Nut Brown).
Not a bad beer but not my favorite brown. It could stand to have less hop bitterness which would let the malt shine a bit more. Pretty low alcohol makes this a decent session beer for cool fall afternoons. Not as impressive as the Torpedo and Kellerweiss but I'd drink it again.
