In Ireland, especially in Dublin in the late 1700's, this style of beer became a favorite of blue collar workers. The drink was known as "plain porter" or just "plain". This is the drink referred to in the famous Flann O'Brien poem, The Workman's Friend: "A pint of plain is your only man." Dark in color, this beer contains a robust flavor from the use of caramel and chocolate malts. 4.8% ABV.
