Pour a good Brandy into large glass filled with cubed ice.
Hold glass at slight angle while filling up glass with Barqs.
Stir lightly.
Test before squeezing small lemon slice.
Best in Collins or HighBall glasses. Needs to be Barq's, or another strong root beer (not A&W or Hensen's). Barq's is also one of few root beer's with caffeine, giving you the perfect kick.
