🥃 🔬 Whiskey Wednesday is getting a little scientific this week.
The crew from and stopped by to break down one of the most talked-about details of a classic whiskey sour: the egg white. 🥚
Our featured Iron Talon Sour showcases The Distillarium Iron Talon Bourbon, crafted in Yakima, Washington. This small-batch, barrel-aged bourbon brings rich caramel notes, natural oils, and a smooth, full-bodied character that makes it the perfect foundation for this balanced cocktail.
Mixed with fresh lemon juice, housemade demerara syrup, egg white, and black walnut bitters, this sour gets its signature silky texture and beautiful foam from the science behind the egg white — creating a cocktail that is smooth, layered, and surprisingly approachable. 🤤
Crafted with a bourbon that reflects the character of the Pacific Northwest and a technique rooted in tradition, the Iron Talon Sour is a limited-time feature you’ll want to experience before it’s gone. ⏳
Stop by your local Washington Stack 571 location and taste what happens when great whiskey meets thoughtful cocktail craft. 🥃
