About

The Blue Grass Cocktail is a charming pre-Prohibition fruit-forward drink that takes its name from Kentucky's storied Bluegrass region — the heartland of American bourbon whiskey production. It combines bourbon with lemon juice, pineapple juice, and maraschino liqueur — a combination that sounds like an odd tropical detour for a bourbon drink, but in practice produces a bright, refreshing, perfectly balanced sour-style cocktail that showcases the best qualities of well-aged Kentucky whiskey. The pineapple provides a sweet, tropical undertone; the lemon brings tartness; and the maraschino adds a floral, slightly nutty complexity that lifts the whole thing above a simple sour template.

Kentucky Roots and History

The Blue Grass Cocktail appears in pre-Prohibition cocktail literature as one of a family of drinks that celebrated the regional identity of American whiskey. Kentucky's Bluegrass region — named for the distinctive grass varieties that carpet its rolling hills and give its thoroughbred horse farms their distinctive look — was already synonymous with bourbon by the late nineteenth century. The cocktail's use of local bourbon alongside tropical pineapple juice reflects the era's enthusiasm for combining American spirits with newly available canned or imported fruits, a combination that produced some of the most enduring classic cocktails before Prohibition closed the bars.

Flavor Profile

The Blue Grass is bright, tart, and fruity — closer in spirit to a sophisticated whiskey sour than to a spirit-forward Manhattan-style drink. The bourbon contributes vanilla, caramel, and oak; the lemon juice provides clean citrus acidity; pineapple adds tropical sweetness and a subtle fermented fruit note; and maraschino liqueur brings a floral, cherry-pit complexity that is its signature note. The balance between the tartness of lemon, the sweetness of pineapple and maraschino, and the depth of bourbon is what makes this cocktail work. Those who enjoy the Whisky Sour will likely love the Blue Grass Cocktail — it is a more complex, aromatic version of the same broad template. The maraschino plays a similar role here to the one it plays in the Yuzu Sour — a small amount of floral liqueur elevating a citrus-spirit foundation.

Maraschino Liqueur: A Key Ingredient

Maraschino liqueur (not to be confused with the syrup from maraschino cherry jars) is a clear, moderately sweet liqueur distilled from Marasca cherries and their pits, then aged and filtered. The most famous producer is Luxardo, from northeastern Italy. The pit distillation gives it a distinctive almond-like, floral, slightly bitter complexity that is unlike any other liqueur in your bar. In the Blue Grass Cocktail, maraschino is used in a relatively small quantity — a quarter ounce to a half ounce — functioning as a flavor modifier rather than a primary ingredient. This is the same technique used in the classic maraschino cocktails page — small doses with outsized effect. According to Difford's Guide, Luxardo is the preferred brand for the maraschino in this cocktail.

Choosing the Right Bourbon

The Blue Grass Cocktail works best with a medium-proof bourbon that has enough vanilla and caramel character to hold its own against the tartness of lemon and the sweetness of pineapple, but is not so heavily oaked that it clashes. Wheated bourbons like Maker's Mark or W.L. Weller work exceptionally well — their softness and sweetness integrate beautifully with the tropical notes of pineapple. High-rye bourbons add spice that can be interesting but can also compete with the delicate maraschino. Compare the bourbon options available on MixDrinkEnjoy's bourbon ingredient page to find the right bottle for your palate and your bar. The Maple Bourbon Sour uses wheated bourbon to similar effect — a useful reference point for how the sweeter bourbon style performs in fruit-forward builds.

How to Make and Serve

Shake all ingredients vigorously with ice for 15 seconds, then double-strain into a chilled coupe glass. The double strain removes ice chips and any pineapple fiber, producing a cleaner, more refined presentation. The cocktail has a pale golden color with a fine foam head from the pineapple juice. Garnish with a thin slice of pineapple or a twist of lemon peel. The Blue Grass is best served cold and consumed promptly — the pineapple juice begins to lose its brightness as the drink warms. See MixDrinkEnjoy's cocktail techniques guide for tips on achieving the right shake and chill for sour-style cocktails.

Variations and Related Drinks

Some bartenders add a dash of Angostura bitters to the Blue Grass, adding spice and aromatic complexity that helps anchor the fruitier elements. A rye whiskey variation is also excellent — drier, spicier, and more assertive, with the pineapple and maraschino reading as even more exotic against the rye's grain character. The Blue Grass can also serve as a template: replace pineapple with fresh mango juice for a richer, tropical version; replace lemon with lime for a different citrus character; or add a half ounce of simple syrup if you prefer a sweeter profile.
