This cocktail is a rebel. A drink too cool for rules. Its got no time for squares. When The Man says that an Old Fashioned must be made with brandy, it grabs a bottle of whiskey. Oranges and maraschino cherries? Nope: peaches. And it keeps the peach theme going with NessAlla Peach Blush Kombucha and Mathilde Peach liqueur. Why? Because it can.
In a highball glass, place peach slices, orange bitters, Angostura bitters, and peach liqueur. Muddle ingredients. Pour whiskey. Add ice. Fill rest of the glass with kombucha.
