Lemon Rosemary Whiskey Sour: A Citrusy, Herbaceous Whiskey Drink

Introduction

There’s something timeless and sophisticated about a whiskey sour—the perfect balance of citrus, sweetness, and whiskey warmth. But when you infuse it with fragrant rosemary, it becomes something truly special. The Lemon Rosemary Whiskey Sour is a bright, herbaceous twist on the classic cocktail, blending the zesty tang of lemon, the smooth depth of whiskey, and the aromatic earthiness of fresh rosemary.

I first came across this delicious variation at a craft cocktail bar during a cozy winter evening. The bartender set the drink down in front of me, with a sprig of charred rosemary resting on the foam. The aroma alone was enough to hook me, but after the first sip, I was completely sold. The slight woodsy bitterness of rosemary complemented the citrus perfectly, while the whiskey provided just the right amount of warmth.

Since then, the Lemon Rosemary Whiskey Sour has become one of my favorite cocktails to make at home. It’s refreshing enough for warm-weather sipping, yet cozy and aromatic enough for fall and winter gatherings. Whether you’re a whiskey connoisseur or just looking to impress guests with a unique cocktail, this is one drink that deserves a permanent spot in your cocktail rotation.

Why These Ingredients Work So Well Together

Each ingredient in the Lemon Rosemary Whiskey Sour plays a crucial role in creating a beautifully balanced, aromatic cocktail:

• Whiskey (Bourbon or Rye) – The rich caramel, vanilla, and spice notes of whiskey pair wonderfully with the bright citrus and earthy rosemary. Bourbon keeps it smooth and slightly sweet, while rye adds a spicier kick.
• Fresh Lemon Juice – The citrusy tang is essential for cutting through the whiskey’s warmth, creating a bright and refreshing sip.
• Rosemary Simple Syrup – Infuses the drink with a subtle herbal earthiness, giving it a unique depth of flavor.
• Egg White (Optional) – Creates a silky foam on top, giving the cocktail a smooth, luxurious texture.
• Angostura Bitters (Optional) – A couple of dashes add a hint of spice and complexity.
• Rosemary Sprig (Garnish) – Enhances the aromatic experience, making every sip more enjoyable.

The combination of these flavors creates a cocktail that is smooth, aromatic, citrusy, and perfectly balanced between sweet and tart.

For the Rosemary Simple Syrup:

Instructions:

Step 1: Make the Rosemary Simple Syrup
