Whiskey Peach Smash Recipe

Is there any better combination than bourbon whiskey and fresh georgia peaches? Maybe, if you threw in a little lemon, mint, and curaao like in this summery cooler from veteran barman dale degroff. Degroff mixed his first whiskey peach smash back in the late 80s but its a thoroughly modern balance, a drink ahead of its time. This drink absolutely requires fresh, juicy, almost-overripe peaches (or nectarines). We tried it once with an out-of-season peach, tough and tannic, and it wasnt awful it was simply a bland smash with peach bits floating in it, and we resolved to never make such a mistake again. Word to the wise: this drink is basically impossible to strain through the strainer of a cobbler shaker. We usually just end up opening the shaker and pouring it into a wire-mesh strainer perched over a large measuring cup, and then serving from the measuring cup into the glass.
