- I hope this isn't a frequently asked question. I checked the FAQs and didn't
- see it.
-
- My friends and I would like to know how to make a "black and tan." (B&T)
- For those of you who don't know, a B&T is Guinness extra stout on top of
- something lighter like Bass pale ale. Legend has it that one can actually
- keep these two layers from mixing while making the drink.
-
- We've tried everything we can think of to carefully prepare this drink
- but every time we try, the two beers mix immediately. We were always
- using Guinness and Bass from bottles. We've tried all kinds of physical
- setups to slowly spread the Guinness on top and to force the Bass to the
- bottom. We've even tried heating one beer while chilling the other.
-
- My fluid dynamics professor said that a chemistry grad student that
- he knows has discovered the secret. He was at a bar having a B&T when
- he noticed that the compressed gas for the Guinness on tap was helium while
- the gas for the Bass was carbon dioxide. He is quite confident that the
- helium does something to the Guinness (makes it lighter?
- changes its viscosity?) that keeps it on top and keeps it from mixing.
- He says that a B&T can not be made using bottled beer because the bottles
- all use carbon dioxide.
-
- I was thrilled to hear this story and it sounds ok to me. However, none
- of my friends buy it. Is there anyone out there who knows the truth?
