Comments

Also sometimes known as Pennsylvania Porter or East Coast Porter. This style does not describe colonial-era products.

History

Commercially brewed in Philadelphia during the revolutionary period as an adaptation of English beer. Evolved later as German immigrants applied lager brewing methods during the second half of the 1800s. Prohibition ended most porter brewing in the US, except in a few regional Northeast and Mid-Atlantic states where it was most popular.

Characteristic Ingredients

Style Comparison
