Guinness Extra Cold
The world-famous popular Irish dry stout. Is there anything else? A distinctive feature is the burnt flavour which is derived from the use of roasted unmalted barley (though this is a relatively modern development since it did not become a part of the grist until well into the 20th century). For many years a portion of aged brew was blended with freshly brewed product to give a sharp lactic flavour (which was a characteristic of the original Porter).
