How to pour a Black & Tan:
Some people believe this is the true version of a Black & Tan. They feel that Guinness/Bass Import Co. has changed the name of this drink to increase their bottom line by selling both products at once. (Pure genius!) Some people will remember that before the mid-80s Guinness was mixed with other beers to give them added taste. In fact, the authors have an advertisement dating from the 1940s that promoted adding Guinness to "your favorite beer" for "added enjoyment." To many old-timers it is a travesty to drink Guinness straight. It must be from the bottle and mixed with a lighter beer.
Some old-timers remember that a B&T was never Guinness floating on top of a lighter beer, either. It was completely mixed 50/50, not separated.
