The Boston Sidecar is a lesser-known cousin of the classic Sidecar cocktail. The Sidecar is a Prohibition-era drink that has stood the test of time, and the Boston variation adds a unique twist by incorporating rum.

  • Origins: While the exact origins are murky, it's believed to have been created in the 20th century.
  • Popularity: This drink is a hit among those who appreciate classic cocktails with a twist.
  • Audience: Ideal for connoisseurs looking for a balance of citrus and spirit-forward flavors.

How Boston Sidecar Tastes?

The Boston Sidecar offers a harmonious blend of sour and sweet with a robust spirit backbone. The rum adds a touch of tropical warmth, while the brandy provides a rich, fruity depth. The triple sec delivers a bright citrus note, making the cocktail complex and well-rounded.

Interesting facts about Boston Sidecar

  • The Boston Sidecar can be considered a hybrid between a classic Sidecar and a Daiquiri.
  • It's a versatile cocktail that can be enjoyed all year round, but it's particularly refreshing in the summer.
  • The drink's name suggests a connection to Boston, but it's more about the variation than the location.


Light Rum

Light rum adds a subtle sweetness and a clean, crisp spirit base to the cocktail. If you skimp on the rum, you'll miss out on the alcoholic backbone that gives the Boston Sidecar its structure. Using too much might overpower the delicate balance with the brandy and triple sec.

Brandy provides warmth and depth, bringing in notes of vanilla and wood depending on its age and origin. Leaving brandy out would significantly flatten the flavor profile. Substituting with cognac would retain the cocktail's character but add a more refined edge.

Triple Sec

Triple sec is the citrusy soul of the cocktail, offering a sweet, orangy zing that complements the lime juice. Using less could make the cocktail too tart, while more would make it overly sweet. Cointreau could be an alternative for a smoother and more intense citrus flavor.

Lime Juice

Fresh lime juice is crucial for the zesty punch and acidity that balances the sweetness of the other ingredients. Too little and the cocktail may become cloying; too much can wince-inducingly sour. Lemon juice could be an alternative but would offer a different type of citrus note.

Add your ingredients to the shaker first, then ice. Fill it up to ¾ of its capacity to ensure enough space for shaking. Hold the shaker with both hands (one on the top and one on the bottom) and shake vigorously. The shake should come from your shoulders, not your wrists.

What is the best type of ice to use when shaking a cocktail?

Using large, dense ice cubes is preferable as they melt slower, reducing dilution and resulting in a well-chilled cocktail.

Why do we strain the cocktail after shaking?

Straining is done to remove any ice shards or herb remnants to ensure a smooth texture and consistent taste.

Can I make a large batch of the Boston Sidecar for a party?

Yes, the Boston Sidecar can be batched for parties. Multiply the ingredients by the number of guests, mix in a large container, chill, and then serve. Keep the ratios the same to maintain the flavor profile.

The garnish plays a dual role by adding visual appeal and enhancing the cocktail's aroma, sometimes contributing subtly to the taste.
