Having recently been March 17th, which is essentially Irish-beer awareness day, we decided to test if we could tell the difference between Guinness draught in the can (with a widget) and in a bottle (nitrogenated, but without a widget).
From time to time we plan on performing a form of taste test, called a triangle test. What follows is the basic framework that will be used in those future tests.
Juice a fresh fruit, or open a bottle? Can we tell the difference?
