Alien Drinks: Alien Secretion, Alien Sludge, Martian Shots and Why They Turn Green
Eight of the eleven drinks in our database with “alien” in the name contain melon liqueur. Two of the other three use blue curaçao or sour apple schnapps, and the last is a gin-and-olive novelty that has no business in this company. The pattern says little about what bartenders imagine extraterrestrials drink and a great deal about what is reliably green on a back bar, because in this family the color is the joke and the recipe is built backward from it.
The Alien Secretion
The Alien Secretion is the one most people are looking for, and also the simplest: equal parts pineapple juice, Malibu coconut rum and Midori, combined and served. None of the three is especially strong, so it drinks like a melon-coconut punch and is often poured long over ice.
The shooter version is the Alien Secretion #2: a quarter ounce each of pineapple juice, Absolut, Midori and Malibu, stirred with ice and strained into a shot glass. Vodka adds heat without flavor, so the melon and coconut stay in front while the shot stops tasting like juice.
In both versions the pineapple juice is doing optical work as well. Its suspended fruit solids scatter light, so where it meets the transparent green of Midori the mixture turns paler, yellower and opaque, and an opaque green reads to the eye as something thicker and stranger than the liqueur on its own. Anyone building a whole table around that effect will find more melon recipes in our Midori shots roundup.
Why every alien drink is green
Color in a mixed drink works by subtraction rather than addition, because each liquid absorbs part of the light passing through it and the eye sees only what survives. A blue liqueur such as blue curaçao absorbs strongly in the orange and red end of the spectrum, while yellow liquids such as orange juice, pineapple juice and butterscotch schnapps absorb mainly in the blue and violet. Put the two in one glass and both ends of the spectrum are removed, which leaves the middle band, and the middle band is green.
Midori arrives already green, its color coming from added food coloring rather than from melon, and it pushes any yellow or blue ingredient it meets further toward the same result. Cream, coconut cream and Irish cream have a different effect, because their fat droplets scatter all wavelengths roughly equally, which whitens and softens whatever color is underneath into a milky pastel. Red is the color to keep away. Grenadine absorbs most strongly in the green part of the spectrum, which is exactly the light the other ingredients left behind, so a splash of it in a green glass produces a muddy brown.
Across the rest of the family the same rules decide what ends up in the glass.
| Drink | What’s in it | Where the color comes from | What you see |
|---|---|---|---|
| Alien Booger | Melon liqueur, vodka, coconut rum, splash of pineapple | Melon liqueur, slightly clouded by pineapple | Translucent bright green |
| Alien Sludge | Pineapple and orange juice, cream of coconut, blue curaçao, coconut and mango rum | Blue curaçao against two yellow juices, whitened by coconut cream | Opaque seafoam green |
| Alien Urine | Midori, coconut rum, peach schnapps, orange juice, sweet and sour | Midori pulled toward yellow by orange juice and sour mix | Cloudy yellow-green |
| Alien Urine Sample | Midori, Malibu, crème de bananes, peach schnapps, sweet and sour, soda, blue curaçao float | Yellow-green base with a blue float | Green that darkens from the top down |
| Green Alien | Midori, lemon juice, Rose’s lime, Sprite, soda water | Midori diluted with clear soda | Pale, bright lime green |
| Mighty Martian | Absolut vodka, sour apple pucker, Midori | Two green liqueurs | Vivid green shot |
Alien Sludge is the cleanest demonstration, since nothing in it is green: an ounce of blue curaçao meets three ounces of yellow juice and an ounce of cream of coconut, and the subtraction does the rest. In the Alien Urine Sample the blue curaçao is floated on last and drifts down into the yellow-green base, so the color shifts while the drink is in hand. For keeping Midori bright instead of murky, what to mix with Midori sorts its mixers by result, and an ingredient search at CocktailBuilder shows how few bottles the whole family needs.
Layered alien shots
Layering keeps colors apart instead of letting them subtract, and three of the shots rely on it. In the Alien Nipple, the bartender puts a half ounce of butterscotch schnapps in the glass, layers a quarter ounce of Irish cream over it and finishes with a quarter ounce of Midori. The Alien Nipple #2 swaps the melon for sour apple pucker, a sharper flavor in a slightly cooler green.
Built in the opposite direction, the Extraterrestrial stacks Midori at the bottom, Irish cream in the middle and Stolichnaya vodka on top, so that the cream separates a green base from a clear cap. The recipe suggests an optional float of Bacardi 151, set alight for a few seconds; Bacardi stopped making 151 in 2016, and the shot loses nothing without the fire.
Stranger still is the Alien Suicide, which layers butterscotch schnapps, then melon liqueur, then arak in thirds of an ounce. Arak is an anise spirit whose aromatic oils stay dissolved only while the alcohol is concentrated, so the shot should be poured without ice; even a little meltwater clouds the top layer.
Martians and other visitors
Some drinks reach the theme by name rather than color. The Martian Martini shakes one ounce of Midori with two of gin, a ratio at which juniper cuts the melon’s sugar, and that makes it the most grown-up drink here. Roswell, named for the New Mexico town associated with the 1947 UFO story, is not green at all: three ounces each of orange juice, cranberry juice and Malibu with a splash of pineapple, which pours as a coral-pink highball. A Little Green Man From Mars is brown Jägermeister and Rumple Minze with a single mint-green maraschino cherry at the bottom, the only green thing in the glass.
