Ingredient Spotlight

Angostura bitters

Angostura bitters is a concentrated aromatic bitter made from a proprietary blend of botanicals, originally developed in the early 19th century in Trinidad and Tobago. It tastes and smells intensely herbal and bitter with warm spice notes (clove, cinnamon) and citrusy undertones, used to add depth to cocktails and some savory recipes. You can find it at liquor stores, larger supermarkets, or online; if you don’t have it, substitute another aromatic bitters (Peychaud’s or orange bitters) or a very small pinch of ground clove/cinnamon plus a few drops of citrus-infused spirit as a rough stand-in.

Jake Woods's note

"This Maple Bourbon Sour is a seasonal twist on a timeless classic — it shines at dinner parties and cozy nights in. Home bartenders will love how simple technique (a dry shake) transforms texture and lifts the maple-forward flavor."

About This Recipe

Maple Bourbon Sour takes the familiar, refreshing structure of a classic sour and dresses it in autumnal warmth. The backbone of bright lemon and caramel-forward bourbon is softened by rich maple syrup—dark or Grade A—whose mineral sweetness reads as more complex than simple syrup. The silky egg-white foam gives the drink a luxurious mouthfeel and carries the aroma of expressed orange and a few Angostura dashes that cut through the sweetness with spiced bitterness. Served in a chilled coupe or over a clear ice rock, it reads like a seasonal signature cocktail rather than a winter novelty.

What makes this version work is the balance and technique: a vigorous dry shake builds a dense, stable froth, and a short cold shake with plenty of ice both chills and lends the right dilution so the lemon isn’t aggressive. Small details—two dashes of bitters, an orange peel rubbed on the rim, or a cinnamon stick for aromatic lift—turn it from a good drink into a memorable one. It’s ideal for home bartenders who want an easy, elegant sipper for cozy evenings, dinner parties, or a fireside nightcap.

How to Make Maple Bourbon Sour

  1. Step 1: Combine and dry shake

    In a cocktail shaker, combine the bourbon, fresh lemon juice, maple syrup, and egg whites. Secure the lid and dry shake (no ice) vigorously for 15–20 seconds to emulsify and build a silky foam.

    For this step

    • 4 ozBourbon
    • 1 1/2 ozFresh lemon juice
    • 1 1/2 ozPure maple syrup (dark or grade A)
    • 2 large (egg white)Large egg whites
    Combine and dry shake
  2. Step 2: Add ice and shake chilled

    Add ice to the shaker and shake hard for 12–15 seconds until the shaker is frosty and the mixture is well chilled. This second shake both cools and slightly dilutes the cocktail for balance.

    For this step

    • 1 1/2 cupsIce cubes
    Add ice and shake chilled
  3. Step 3: Strain and finish with bitters

    Double-strain the mixture into two chilled coupe glasses (or rocks glasses with fresh ice), dividing foam evenly. Add two dashes of Angostura bitters to each drink and, if desired, use a toothpick to gently swirl the bitters into a decorative pattern on the foam.

  4. Step 4: Garnish and serve

    Express an orange peel over each glass to release oils, rub the rim with the peel, and drop it in as a twist. Optionally add a cinnamon stick for aroma and serve immediately while the foam is set and fragrant.

Maple Bourbon Sour Tips

Dry shake first

Shaking without ice emulsifies the egg white and maple for a creamy, stable foam; 15–20 seconds is enough when you shake vigorously.

Use plenty of ice

When you add ice for the second shake, use large, cold cubes and shake until the shaker is frosty to ensure proper dilution and chilling.

Double strain for texture

Strain through a fine mesh into your glass to remove tiny ice shards and maple residue so the foam stays smooth and presentable.

Adjust maple to taste

Dark maple is more robust and may need less; start with 1.5 oz but reduce to 1–1.25 oz if your bourbon is sweeter or you prefer brighter lemon.

Layer the bitters

Add bitters drops on the foam then use a toothpick for a gentle swirl—this gives aroma without breaking the head's structure excessively.

Maple Bourbon Sour Variations and Substitutions

Vegan aquafaba swap

Replace the two egg whites with 2 tablespoons aquafaba per egg white (about 4 tablespoons total) and dry shake the same way for a vegan foam alternative.

Smoky whiskey twist

Substitute half the bourbon with a small measure of peated Scotch (25–50%) for a smoky, campfire note that complements maple beautifully.

Spiced maple syrup

Infuse your maple with a cinnamon stick and a clove for 24 hours, then strain—this adds a warm spice layer without needing extra garnish.

Citrus swap: lime

Use fresh lime juice instead of lemon for a tarter, brighter sour that makes the maple feel more pronounced and tropical.

How to Store and Make Maple Bourbon Sour Ahead

Cocktails with egg white are best enjoyed freshly made; the foam will collapse and aromatics will fade after sitting. You can pre-batch the bourbon, lemon juice, and maple in the refrigerator for up to 24 hours, but add and shake with egg white just before serving. Do not reheat; simply remix and re-shake if flavors seem separated after chilling.

What to Serve With Maple Bourbon Sour

Serve alongside salty bar snacks like spiced pecans, charcuterie with aged cheddar, or bacon-wrapped dates to play off the maple's sweetness. For a dessert pairing, lean toward warm spice desserts—pear galette or gingerbread—so the cocktail's citrus brightness refreshes the palate between bites.

Maple Bourbon Sour FAQs

Is it safe to use raw egg whites in this cocktail?

Most healthy adults can safely consume raw egg whites, but if you are concerned, use pasteurized egg whites or aquafaba as a vegan substitute to eliminate any risk.

Can I make this drink without shaking with egg whites?

You can omit the egg white, but the texture will be thinner and lack the silky foam; consider a smaller amount of simple syrup or maple to maintain body if skipping the egg.

What grade of maple syrup should I use?

Dark or Grade A robust maple adds caramel and molasses notes that pair well with bourbon, while lighter syrup yields a more delicate sweetness—choose based on how forward you want the maple to be.

How much should I adjust for different bourbons?

If your bourbon is high-rye and spicy, stick to the recipe; for very sweet, low-proof bourbons reduce maple by 0.25–0.5 oz to keep the lemon lively.

Why do you double-strain the cocktail?

Double-straining removes tiny ice chips and any unmixed maple particles so the foam looks clean and the mouthfeel stays smooth, particularly important for egg-white drinks.
