Porters were one of the first beers imported to the US and quickly caught the attention of George Washington as his drink of choice. Similar to English Porters these beers have more of a hop profile from the use of American varieties.
Similar to Hefeweizen, American Wheat beers use a cleaner yeast and have more of a hop aroma and flavor. The yeast used does not produce the banana and clove phenolics you are used to with German styles.
Brewed with the same dark malt that make English Stouts, these beers are also generously hopped with bold North American varieties. While the roasted bitterness is still strong there is an underlying hop bitterness as well.
