The Highball’s Evolution: How a Classic Order Became 2026’S It-Drink
The difference between a watery drink and a crisp classic cocktail recipe comes down to balance. If you pour equal parts whiskey and soda, the spirit overpowers the carbonation, leaving the drink flat and hot. If you dump five parts soda over two tiny ice cubes, the drink becomes thin, washing out the spirit’s malty character within two minutes.
Professional bars focus on a 1:3 to 1:4 whiskey and soda ratio. For a standard domestic build, this translates to 1.5 ounces of spirit to 4.5 or 5 ounces of ice-cold club soda.
The temperature of the mixer matters as much as the pour size. Carbon dioxide remains dissolved in cold liquids far longer than warm ones. Adding room-temperature club soda to ice triggers immediate thermal shock, forcing gas out of solution in a violent foam and leaving a dull liquid behind. Both the bottle of mixer and the spirit should ideally sit in the refrigerator or freezer before you build the drink.
