Rainbow

What is Rainbow?

The Rainbow shot belongs to the long tradition of layered shooters that has been a fixture of cocktail bartending since the 19th century, when bartenders developed the technique of floating spirits and liqueurs of different densities to create visually dramatic presentations known collectively as Pousse-Café drinks. The Rainbow simplifies that tradition into a three-layer non-alcoholic shot, using grenadine, pineapple juice, and blue curaçao to create a vivid red, yellow, and blue gradient. While most layered shots use spirits and liqueurs, the Rainbow is unusual in containing only juice, grenadine syrup, and a small measure of blue curaçao, making it considerably lower in alcohol than most layered shooters and accessible to drinkers who prefer something light or are pacing themselves through a long evening. The drink became a fixture of LGBTQ+ Pride celebrations through the 2010s and 2020s, when its colourful presentation made it a natural fit for Pride month bar promotions and themed parties. The visual layering technique remains the central appeal: a properly poured Rainbow shot looks like a small piece of art rather than a drink, and the photographic appeal has made it one of the most popular shots on social media platforms where colour-driven content performs best.

What makes this shot special isn’t just the flavor, it’s the technique. The layering creates a smooth transition of colors while delivering a sweet, fruity taste with a citrusy finish. If you enjoy playful, eye-catching drinks like the Electric Smurf, this one will feel right at home in your lineup.

Taste profile

The Rainbow shot is sweet, fruity, and surprisingly approachable for a drink that initially looks like pure colour. The grenadine bottom layer leads the palate with its concentrated pomegranate sweetness, providing the most dominant flavour element in the shot. Pineapple juice in the middle delivers a bright, tangy tropical fruitiness that balances the grenadine's heaviness with a lighter, more aromatic character. Blue curaçao on top provides a subtle bitter orange peel note alongside the curaçao's characteristic sweetness, which gives the finish a complexity that pure juice would lack. As the layers blend on the palate during consumption, the three flavours combine into something resembling a tropical fruit punch with a slight orange edge: sweet, juice-forward, and immediately appealing without the burn or sharpness of a spirit-based shot. The very low alcohol content from the small blue curaçao measure means this drinks more like a flavoured juice cocktail than a shooter, which is a feature rather than a flaw and accounts for much of its broad appeal.

Serving suggestions

Layering is the entire craft of this shot and the technique requires patience and a steady hand. Pour the grenadine into the shot glass first, filling approximately one third of the glass: grenadine is the densest of the three ingredients and forms the stable base layer. Hold a bar spoon just above the surface of the grenadine, curved side up, and pour the pineapple juice very slowly over the back of the spoon so it floats gently on top rather than splashing through. Repeat the technique with the blue curaçao, pouring even more slowly as it is the lightest of the three layers and most likely to disturb the layers below if poured too quickly. Chill all three ingredients before starting: cold liquids are denser and more viscous than warm ones, which helps the layers hold their separation longer. Use clear shot glasses with straight rather than tapered sides to maximise the visibility of the layered colours. Serve immediately, as the layers will gradually blend within five to ten minutes. For a Pride or themed party presentation, line up multiple Rainbow shots on a tray under good lighting to create a striking visual centrepiece.
