2 oz of Smirnoff vodka (or Vodka)
pepsi cola (or coke)
1.5 oz of Kahlua coffee liqueur (or coffee liqueur)
Mix the Vodka, and the Kahlua in a shaker with ice, pour in to a Old fashion glass and top the glass of with Pepsi, It is also good with other types of vodka, Also you may like to add ice to the glass if the Pepsi is warm, Best served cold!\r
My math made it out to be about 15% not to high for the point to get drunk, but god to sit back and relax.
