An IBA official cocktail is one of many cocktails selected by the International Bartenders Association (IBA) for use in the annual World Cocktail Competition (WCC) in bartending.
IBA cocktails are specified in centilitres (cl) rather than the more commonly used millilitres (ml). 3 cl are approximately equivalent to 1 U.S. fluid ounce (1.4% more). 0.5 cl is approximately 1 U.S. teaspoon. This is official list of 90 cocktails IBA (from february 2020).
