History
Originating in London in the early 1700s, porter evolved as a more heavily hopped and aged (keeping) version of the Brown Beer popular at the time. It evolved many times based on various technological and ingredient developments (such as the invention of black malt in 1817, and large-scale industrial brewing), as well as consumer preferences, wars, and tax policy. It became a highly-popular, widely-exported style in the early 1800s before declining by the 1870s as it changed to a lower gravity, unaged beer. As gravities continued to decline in all UK beers in the first half of the 1900s, styles stopped being made (including porter, gone by the 1950s). The craft beer era led to its re-introduction in 1978.The name is said to have been derived from its popularity with the London working class performing various load-carrying tasks of the day. Parent of various regional interpretations over time, and a predecessor to all stouts (which were originally called “stout porters”).There is no historic connection or relationship between Mild and Porter.
