Sierra Nevada - Tumbler Autumn Ale

Sierra Nevada - Tumbler - Chico, CA 5.5% abv
12 oz dark brown bottle. No freshness date.
I enjoy this dark auburn, brown leathery color with a medium-sized beige head on top. Loads of sticky lacing cling to the glass throughout.
The aroma is mostly malt-driven, with dry grain, caramel malt and farina wheat smells. There is a bit of fruit and citrus peel to the hop aroma.
The flavors are under-whelming. I expected a strong, sweet malty taste with a solid hop blend for support, but was a little disappointed. It sort of reminds me of a New Castle Ale, except with a bit more of a hop and alcohol kick.
The body has an unexpected spritzy effervescence. I would like a little more solid, rich malty body in an autumn ale. Something to stand up to creamy, thick autumn stews, perhaps.
