Bosun's moustache by "red bricks" is a bitter ale because to make it, we use copious amounts of american hops "cascade", "citra", "centennial", and "chinook" - and not only in the process of brewing, but maturation as well. All that so you could get a nose of the kind of tropical fruit aroma that would make a bosun's moustache curl as you raise the glass to your lips.
