On the darker end, you have beers such as the porters. 

These are beers typically brewed with darkly roasted malts that tend to be full-bodied with malt-forward flavors. These often have a higher alcohol content, but you will learn that few things about these styles are objective as you start looking at them. 

A good example of a porter is the fantastic Fat Nerd Vanilla Porter from Yulli's Brews, which is backed by a lovely chocolate & roasted malt character.

The Catchment Brewing, is offering Cow Tipper a creamy smooth stout to enjoy during winter.
