Blue Moon Cocktail Recipe: A Classic Violet-Tinted Gin Drink With a Floral Twist

The Blue Moon cocktail is a classic gin-based beverage characterized by its pale lavender or blue-violet hue and subtle floral notes. This cocktail, though not as universally recognized as others in the same category, has made a notable impression due to its use of crème de violette — a violet-flavored liqueur that gives the drink its distinct color and aromatic complexity.

This article provides a detailed, step-by-step guide to preparing the Blue Moon cocktail, including ingredient notes, preparation instructions, historical context, and tips for achieving optimal flavor and presentation.

Overview of the Blue Moon Cocktail

• Primary Base: Gin

• Flavor Profile: Floral, citrus, botanical

• Key Liqueur: Crème de violette

• Glassware: Coupe or cocktail glass

• Typical Garnish: Lemon twist or no garnish

The Blue Moon is often compared to other crème de violette cocktails such as the Aviation. However, unlike the Aviation, the Blue Moon omits maraschino liqueur, resulting in a simpler, more focused flavor profile centered on the floral and citrus notes.

Ingredients

Below is a standard recipe for a single serving of the Blue Moon cocktail:

• 2 oz (60 ml) gin – Preferably a London Dry gin for a strong botanical presence

• 1/2 oz (15 ml) crème de violette – A violet liqueur with floral aroma and violet-blue color

• 1/2 oz (15 ml) freshly squeezed lemon juice – Adds acidity and balance

• Ice – For shaking

• Optional garnish – Lemon twist

Ingredient Notes:

Gin: The gin serves as the base spirit. London Dry gin is a common choice, though more floral-forward gins such as those with lavender, orris root, or elderflower botanicals may enhance the drink’s aromatic profile.

Crème de Violette: This is a French liqueur made from violet petals. Brands such as Rothman & Winter or Giffard are widely used. The amount used can be adjusted slightly depending on color preference or desired sweetness.

Lemon Juice: Freshly squeezed juice is essential. Bottled alternatives may produce inconsistent acidity and flavor.

Equipment Needed

• Cocktail shaker – To combine and chill ingredients

• Hawthorne strainer or fine mesh strainer – For a smooth pour

• Jigger or measuring tool – For accurate proportions

• Citrus juicer or reamer – To extract fresh lemon juice

• Chilled coupe glass – Preferred serving vessel

Instructions

Follow these steps for optimal preparation:

1. Chill the Glass: Place the coupe glass in the freezer or fill it with ice water while preparing the cocktail.

2. Measure Ingredients: Add 2 oz gin, 1/2 oz crème de violette, and 1/2 oz freshly squeezed lemon juice into a cocktail shaker.

3. Add Ice: Fill the shaker about three-quarters full with ice.

4. Shake Vigorously: Shake the mixture for 10–15 seconds until the shaker feels cold to the touch. This chills and slightly dilutes the drink.

5. Strain into Glass: Empty the ice from the coupe glass if using ice water, and strain the shaken cocktail into the chilled glass.

6. Garnish (Optional): Add a thin lemon twist or lemon zest strip. Avoid over-garnishing to maintain the drink’s clean appearance.

Flavor Characteristics

• Aroma: Floral and citrusy, dominated by the violet liqueur with hints of juniper and lemon oils if a twist is used.

• Taste: Balanced between sweet and tart, with a noticeable floral element from the crème de violette and botanical sharpness from the gin.

• Finish: Clean, slightly dry, with lingering floral undertones.

Historical Background

The Blue Moon cocktail first appeared in print during the 1940s in "The Savoy Cocktail Book" and similar period manuals. It is believed to be a simplified version of the earlier Aviation cocktail, which included both crème de violette and maraschino liqueur.

During the mid-20th century, the availability of crème de violette declined, leading to a drop in popularity for both the Blue Moon and Aviation. However, with the recent revival of classic cocktail culture and the return of niche liqueurs, the Blue Moon has reemerged in cocktail bars and home bartending repertoires.

Variations and Substitutions

Several variations of the Blue Moon cocktail can be made by altering its components:

• With Maraschino Liqueur: Adding 1/4 oz maraschino liqueur creates a hybrid between the Blue Moon and the Aviation.

• Using Different Gins: Floral gins such as Hendrick’s or local craft gins can emphasize different flavor notes.

• Replacing Lemon with Lime: Substituting lime juice introduces more bitterness and changes the balance of the drink.

• Non-Alcoholic Version: Mocktails can mimic the look and feel of the Blue Moon by combining violet syrup with lemon juice and sparkling water, though the flavor will differ.

Presentation Tips

• Serve in a chilled coupe for the most traditional presentation.

• The color of the cocktail can vary from lavender to light blue, depending on the brand and amount of crème de violette used.

• Avoid garnishes that overpower the floral aroma; if garnishing, a thin lemon twist is recommended.

• Ensure all ingredients are fresh and well-measured to maintain clarity and color balance.

Storage and Batch Preparation

• Do not store mixed Blue Moon cocktails. The citrus component causes degradation in flavor and color after mixing.

• Crème de violette and gin are shelf-stable and can be stored in a cool, dark place. Lemon juice should be squeezed fresh just before use.

• For batching at events, prepare a premixed combination of gin and crème de violette, then add lemon juice and shake individual servings to order.

Nutritional and Alcohol Content Estimate

A typical Blue Moon cocktail contains:

• Approximately 20–25% ABV depending on the gin and dilution during shaking.

• Around 180–220 calories, mainly from alcohol and sugar in crème de violette.

• Very minimal fat or protein content; contains small amounts of vitamin C from lemon juice.

Conclusion

The Blue Moon cocktail remains a minimalistic yet visually striking drink rooted in pre-Prohibition and mid-century cocktail traditions. With only three ingredients—gin, crème de violette, and lemon juice—it offers a clear, balanced profile that is easy to replicate and modify at home. Its subtle violet aroma and pale purple hue make it a distinctive option in the world of classic cocktails. When prepared with precision and quality ingredients, it showcases both the versatility of gin and the delicate appeal of floral liqueurs.
