The Amaretto Sour is a classic sweet and tart cocktail featuring Italian almond liqueur, fresh lemon juice, and a splash of high-proof bourbon. Popular for its rich marzipan flavor and creamy frothy topping, this perfectly balanced drink offers a sophisticated upgrade to the overly sugary versions of the past.

 How to make an Amaretto Sour

You can make a restaurant-quality version of this drink in just a few simple steps:

1. Combine 1.5 ounces of amaretto, 0.75 ounces of bourbon, 1 ounce of fresh lemon juice, 1 teaspoon of simple syrup, and 0.5 ounces of egg white in a cocktail shaker.
2. Shake vigorously without ice for 15 seconds to create a thick foam.
3. To cool the drink, add a big scoop of ice to the shaker and shake it for another 15 seconds.
4. Strain the mixture into a glass filled with fresh ice.
5. Garnish with a lemon twist and a brandied cherry.

How Did the Amaretto Sour Evolve from the 1970s to Today?

Cocktail history is filled with drinks that experienced massive popularity before falling out of favor. The amaretto sour fits this narrative perfectly. Importers of Italian amaretto liqueur introduced the original recipe to the United States in the mid-1970s. The goal was to boost awareness of the spirit, and the strategy worked flawlessly. Drinkers loved the sweet, accessible flavor profile.

However, the quality of the cocktail declined rapidly during the 1980s and 1990s. High-volume bars began replacing fresh citrus juice with cheap, artificial sweet-and-sour mixes. Because amaretto is already a sweet liqueur, mixing it with heavy artificial syrups results in a cloying, unbalanced beverage. The drink earned a poor reputation among cocktail enthusiasts.

The modern craft cocktail movement completely rehabilitated this classic drink. Around 2010, Portland bartender Jeffrey Morgenthaler published a heavily revised recipe that changed the benchmark for the beverage. He recognized that classic amaretto was too sweet and lacked the alcoholic punch of traditional base spirits. By adding high-proof bourbon and restoring the use of fresh lemon juice and egg whites, he created a complex, nuanced drink.

Modern bartenders now treat this recipe with the respect it deserves. The current iteration leans heavily into the rich, nutty notes of the liqueur while maintaining a crisp, tart finish.

What Exactly is Amaretto Liqueur?

Amaretto translates from Italian to "a little bitter." This sweet liqueur originated in Saronno, Italy, and boasts a history that stretches back hundreds of years. The flavor profile is distinctly nutty, characterized by strong notes of marzipan, vanilla, dark cherry, and baking spices.

Interestingly, many top amaretto brands do not actually use almonds to achieve this flavor. Producers often extract the essential oils from the kernels of apricots, peaches, or cherries. These fruit pits, known as drupes, contain the exact same flavor compounds found in almonds. The oils are then blended with a neutral spirit, burnt sugar, and water.

Different brands offer varying levels of sweetness and complexity. Disaronno Originale remains the most famous and widely available option, offering a highly sweet, classic marzipan flavor. Brands like Lazzaroni and Luxardo provide slightly drier alternatives with robust herbal undertones.

Which Ingredients Make the Best Amaretto Sour?

Building the perfect cocktail requires high-quality components. Using the right specific ingredients will elevate your drink from a basic mix to a professional-tier beverage.

The Essential Cocktail Components

• Amaretto liqueur: This is the foundational flavor of your drink. You will need 1.5 ounces of a premium brand.
• Cask-Proof Bourbon: Standard bourbon sits around 40% ABV. Cask-proof or overproof bourbon ranges from 50% to 65% ABV. You only need 0.75 ounces. The high alcohol content cuts through the heavy sugar of the liqueur and adds a wonderful backbone of oak and vanilla.
• Fresh Lemon Juice: Squeezing your lemons fresh is a strict requirement. Bottled lemon juice contains preservatives that completely alter the taste of the drink. You will need 1 full ounce.
• Rich Simple Syrup: Rich syrup uses a two-to-one ratio of sugar to water. Adding just 1 teaspoon balances the harsh acidity of the fresh lemon.
• Egg White: Half an ounce of fresh egg white provides a silky, velvety texture.

How Do You Achieve the Perfect Cocktail Froth?

A signature feature of any great sour cocktail is the thick, meringue-like foam resting on top of the liquid. This foam softens the sharp acidity of the citrus and provides a luxurious mouthfeel.

The Science of the Dry Shake

Bartenders use a specific technique called a "dry shake" to build this foam. When you shake egg whites alongside citrus juice and alcohol without any ice, the physical agitation causes the proteins in the egg to unfold and trap air. The acid from the lemon juice helps stabilize these protein walls.

You must shake the room-temperature ingredients vigorously for at least 15 seconds. After this initial dry shake, you add ice to the shaker. The second shake, known as the "wet shake," rapidly drops the temperature of the drink and provides the necessary water dilution.

Vegan and Dairy-Free Options

You do not need to consume animal products to enjoy a frothy cocktail. Aquafaba serves as a perfect vegan substitute for egg whites. The starchy liquid inside a typical can of chickpeas is called aquafaba.

Two tablespoons of aquafaba will replace one standard egg white. You use the exact same dry shake technique. The resulting foam is nearly identical in texture, and the faint bean flavor completely disappears behind the strong almond and lemon notes.

Cocktail Characteristics

Preparation Time	Yield	Estimated Calories	Primary Flavor Profile
5 Minutes	1 Drink	305 kcal	Sweet, tart, and Nutty

Ingredients List

• 1 1/2 ounces premium amaretto liqueur
• 3/4 ounce cask-proof bourbon (such as Wild Turkey 101 or similar)
• 1 ounce freshly squeezed lemon juice
• 1 teaspoon rich simple syrup (2:1 sugar to water ratio)
• 1/2 ounce fresh egg white (or 2 tablespoons aquafaba)
• Ice cubes (for shaking and serving)
• 1 Lemon twist (for garnish)
• 1 Brandied cherry (for garnish)

Preparation Instructions

1. Prepare your glassware: Place a standard rocks glass in the freezer to chill while you build the drink.
2. Combine the liquid ingredients: Measure the amaretto, bourbon, lemon juice, simple syrup, and egg white into the bottom half of your cocktail shaker.
3. Perform the dry shake: Seal the shaker completely. Shake the mixture vigorously for 15 seconds without any ice. Ensure you have a tight grip, as the expanding gases from the egg white can sometimes push the shaker apart.
4. Perform the wet shake: Open the shaker and fill it halfway with ice cubes. Seal it again and shake vigorously for another 15 seconds until the outside of the metal tin feels frostbitten.
5. Strain and serve: Remove your chilled rocks glass from the freezer and add one large, fresh ice cube. Use a Hawthorne strainer to pour the cocktail over the fresh ice.
6. Garnish the drink: Express the oils from the lemon twist over the top of the foam. Gently place the brandied cherry on the glass's edge after skewering it with the lemon twist.

Are There Alternative Versions of This Drink?

The beauty of cocktail crafting lies in experimentation. You can easily modify the base recipe to suit different flavor preferences or dietary needs.

The 3-Ingredient Quick Mix

If you do not have bourbon or egg whites on hand, you can still create a delicious, simple version of this drink. Combine 2 ounces of amaretto, 1 ounce of fresh lemon juice, and a splash of lemon-lime soda. Shake the amaretto and lemon juice over ice, strain into a glass, and top with the carbonated soda. This results in a highly refreshing, lower-alcohol patio drink.

The Amaretto Stone Sour

This variation introduces a bright, tropical element to the glass. You simply add 1 ounce of fresh orange juice to the standard recipe. The orange juice naturally sweetens the cocktail, meaning you can entirely omit the simple syrup.

The Godfather Sour

The Godfather is a classic cocktail made by mixing equal parts scotch whisky and amaretto. You can turn this concept into a sour by swapping the bourbon in our main recipe for a peaty, smoky Scotch. The heavy smoke of the scotch creates a brilliant contrast against the candied almond flavor of the liquor.

What Are the Best Expert Tips for Entertaining?

Serving craft cocktails at a dinner party can feel overwhelming. These practical kitchen insights will help you serve perfect drinks to your guests with minimal stress.

Batching for a Crowd
You can easily multiply this recipe to serve eight to ten people. Combine all the liquid ingredients (except the egg whites) in a large pitcher up to a day in advance and store it in the refrigerator. When you are ready to serve, pour individual portions into a shaker, add the egg white, and perform your dry and wet shakes on demand.

Using the Right Ice
Ice is a vital ingredient in any cocktail. Standard refrigerator ice cubes melt incredibly fast, which will water down your carefully balanced drink. Invest in a silicone mold that creates large, two-inch square ice cubes. A large cube has less surface area relative to its volume, meaning it keeps the drink ice cold while melting at a fraction of the speed.

Enhancing the Aromatics
A large portion of what we taste actually comes from our sense of smell. Raw egg whites can sometimes leave a very faint, damp odor on the top of the foam. You can eliminate this completely by adding three drops of Angostura bitters to the top of the finished foam. The spiced aromas of the bitters will hit the nose first, enhancing the entire drinking experience.

Frequently Asked Questions About the Amaretto Sour

How many calories are in a standard sour amaretto cocktail?
A standard recipe utilizing bourbon and egg whites contains approximately 305 to 315 calories. The majority of these calories come directly from the high sugar content of the amaretto liqueur and the dense caloric nature of the base alcohol.

Is it safe to consume raw egg whites in drinks?
The risk of foodborne illness from consuming raw, pasteurized eggs is statistically very low, but it is not zero. The acidity of the lemon juice and the alcohol content do help inhibit bacterial growth. However, pregnant individuals, the elderly, and those with compromised immune systems should always opt for the vegan aquafaba alternative.

How long does freshly squeezed lemon juice last?
For the absolute best flavor, you should use lemon juice within four hours of squeezing it. As the juice oxidizes, the bright, snappy flavors begin to dull and turn bitter. You can store leftover juice in an airtight container in the fridge for up to 24 hours, but it will lose its peak vibrancy.

What is the alcohol by volume (ABV) of this drink?
When made with 1.5 ounces of a 28% ABV amaretto and 0.75 ounces of a 55% ABV cask-proof bourbon, the final drink, sits at roughly 16% to 18% ABV after accounting for water dilution from the ice. This makes it a moderately strong cocktail, comparable to a robust glass of wine.

Can I use bottled sweet and sour mix?
Beverage professionals strongly discourage using commercial sour mix. Bottled mixes rely on high fructose corn syrup and artificial citric acid. Mixing these artificial ingredients with sweet amaretto throws the cocktail entirely out of balance and masks the delicate herbal notes of the liqueur.

Why This Classic Cocktail Remains a Happy Hour Staple

The revival of the sour amaretto cocktail recipe proves that no drink is beyond saving. By understanding the chemistry of the ingredients and respecting the balance between sweet and tart, you can transform a discarded retro drink into a modern masterpiece.

The combination of premium Italian liqueur, high-proof American whiskey, and fresh citrus creates a flavor profile that appeals to nearly every palate. The bourbon provides enough heat to satisfy seasoned whiskey drinkers, while the sweet marzipan notes remain approachable for cocktail beginners.
