Porters and stouts are dark beers that originated in London pubs in the 18th century. Stouts are a stronger and fuller-bodied variation of porters, with typically 7-8% alcohol. Porters are well hopped, made from brown malt and descended from brown beer. This class of beers was popular with the street and river porters in London at the time, hence their name. The strongest of these were called stout porter but the term was later shortened to just stout.
Porter was first created in the 18th century in a London pub. It was a blend of younger pale ales and older darker ales.
Stout was originally called “stout porter.” It was a version of the London pub drink that was created by London breweries to be sold on a larger scale. The word “porter” was eventually dropped from the name.
Porter is usually brewed using malted barley, although a few varieties use unmalted roasted barley.
Stout is brewed with unmalted roasted barley, which adds roasted smells and dry bitterness to beer.
Porter is sweeter than stout.
Due to the roasted barley, stout has deeper roasted notes than porter and has a dry bitter taste.
