From the makers:

"Murray's Dark Knight is made in the traditional Porter style from six specialty malts. It is full bodied, rich and complex. The beer is a deep ruby colour, with a creamy, off-white head. Murray's Dark Knight has an aroma of caramel and bittersweet chocolate and finishes with a balanced bitterness.

It's ideal with rich red meat casseroles, or for the more adventurous, try with Chocolate Mud Cake."
