If you love to drink beer both Guinness and Bass are great beers to drink. Individualy they are excellent but when you combine the two a magical/wonderfull thing happens! A Black and Tan is born!
Hold your pint glass at an angle, and fill halfway with your bottle of Bass Ale.
Slowly pour your bottle of Guinness into the pint glass over the upside-down spoon; you want this to be a slow/slow pour so separation will begin between the two.
If you are patient and take your time you will be rewarded with a true Black and Tan.
