3 part of red zinfandel wine (or Byrrh Wine)
2 part of Coca-Cola (or coke)
1 part of bacardi silver o3
It's easier to just guess when pouring one of these. The way you fill it is your choice, but the order is pyramid from largest to smallest, adding the extras afterward: White Z. first, then the Coke/Pepsi, then the Biaardi. Optional slice of strawberry or dallop of whipped cream. No need for mixing, watching the drink swirl (if you've done it right) is nice eye-candy for the prospective drinker who's next in line. The extras are just for kicks.
