The original porter was modeled after a popular beer mixture known as the 'three threads'. The three threads was a three beer mixture popularized in London in the early 1700s. Since then, porters have developed into their own unique style. Much porter brewing died out during the Second World War, but since then there has been a resurgence of the style in both England and the United States. Yuengling of Pennsylvania still produces a porter brought to the US by German immigrants in the 1800s. Porters are very dark in color, often with reddish-brown highlights. Beers of this type tend to have smooth flavors of chocolate and caramel with a gentle backing of malty sweetness. Compared to British porters, American interpretations are more bitter, with a dry and snappy exit from the mouth. Porters are an excellent match for grilled meats and vegetables. They can also complement chocolate desserts, stepping in where a dinner wine may fall short.
