Which of the following beers is classified as an American Porter?

The classification of Founders Porter as an American Porter aligns with the style's defining characteristics. American Porters are known for their robust malt profiles that often present roasted malt flavors, hints of chocolate, and a balanced hop presence that can lean more toward hop-forward than traditional English Porters. Founders Porter exemplifies these traits through its rich, chocolatey, and slightly roasted malt characteristics paired with a noticeable but well-integrated hop bitterness.

In contrast, Brooklyn Brown Ale and Mondo James Brown Ale are both classified as Brown Ales, which typically have a maltier profile with caramel and toasty notes without the same level of roast or bitterness found in Porters. Bell's Kalamazoo Stout, while a stout and darker than a Porter, falls into a different category entirely, focusing more on the creamy, rich body and less on the roasted malt complexities that distinguish a Porter. Thus, Founders Porter stands out as the appropriate example of an American Porter.
