The Pumpkin Spice Whiskey Sour keeps the familiar bourbon-sour structure but adds pumpkin purée and baking spice for a distinctly autumn profile. Bourbon supplies oak and caramel, lemon keeps the drink bright, and pumpkin adds body rather than overwhelming sweetness. With egg white, the cocktail becomes silkier and more aromatic under a light dusting of nutmeg.
A Seasonal Whiskey Sour Variation
The Whiskey Sour is a long-established combination of whiskey, citrus, and sweetener. This pumpkin version is a modern seasonal riff rather than a historical standard. It preserves the sour framework while introducing pumpkin purée and spice, which make the drink fuller and more textured than the classic without replacing the bourbon and lemon at its core.
What You'll Need
Ingredients
- Bourbon - provides the whiskey backbone with oak, vanilla, and caramel notes.
- Lemon Juice - supplies the acidity that keeps pumpkin and syrup in balance.
- Pumpkin Purée - adds body and earthy pumpkin flavor.
- Simple Syrup - rounds the lemon and supports the sour balance.
- Pumpkin Spice - adds cinnamon-led baking-spice aroma.
- Egg White - optional, but creates a silkier texture and stable foam.
- Nutmeg - finishes the drink with fresh aromatic spice.
Rye whiskey can replace bourbon for a drier, spicier result. Aquafaba can replace egg white when a similar foam is wanted without egg.
Equipment
- Cocktail shaker
- Jigger
- Hawthorne strainer
- Fine-mesh strainer
- Whiskey Sour Glass
Pumpkin With a Proper Sour Backbone
The drink works because pumpkin is treated as texture and flavor, not as the primary sweetener. Lemon still defines the sour, bourbon remains recognizable, and the simple syrup bridges the two. Fine-straining is especially useful here because it removes larger pumpkin solids and keeps the finished texture smooth.
Substitutions & Variations
- Use rye whiskey - adds more spice and a drier grain profile.
- Use maple syrup - replace the simple syrup with a smaller amount of maple for a deeper fall variation.
- Use aquafaba - creates foam without egg white.
- Skip the foam - omit egg white and shake normally for a lighter texture.
Helpful Tips
- If using egg white, dry shake before adding ice, then shake again with ice to chill and dilute.
- Use fresh lemon juice because the pumpkin can mute dull acidity quickly.
- Fine-strain to remove larger purée particles.
- Chill the Whiskey Sour Glass before straining.
- Grate nutmeg lightly over the foam; too much can overpower the drink.
- When using raw egg white, use fresh, properly handled or pasteurized egg white when possible.
