The average cocktail uses: 1 1/2 ounces (the average shot) of a base liquor (i.e. vodka, gin, rum, etc.). Liqueurs are typically poured at 1/2 to 3/4 ounce. Accent juices (i.e. lemon and lime) typically use 1/4 to 1/2 ounce. Filling a highball or tall drink with juice or soda often requires 4 to 6 ounces.
