Purple Rain Drink: The Cocktail, the Shot, and a Pitcher That Stays Purple

Our first Purple Rain came out brown. Not a pretty brown, either. It looked like pond water in a highball glass, and we stood around the kitchen trying to work out what went wrong, because the recipe said gin, cranberry and blue curaçao, and red plus blue is supposed to make purple. Every kindergartner knows that.

It turns out the kindergartners are only mostly right. Once we understood why, the drink came out a deep violet every time, which is a fine thing to have in hand in October, when half the parties we get invited to want something purple, black or orange on the table.

The name nods to Prince, of course. The drink itself has sat on bar menus for decades. It’s tart and fizzy, and you can spot the color from across the room.

What’s in a Purple Rain

Our Purple Rain is gin, sweet and sour mix, cranberry juice, blue curaçao and soda water. A good starting build looks like this:

1 1/2 oz gin
2 oz cranberry juice
1 oz sweet and sour mix
1/2 oz blue curaçao
soda water to top

Shake everything except the soda with ice, strain into a tall glass over fresh ice, and top with soda. The gin keeps it from tasting like juice, and the botanicals play nicely with cranberry’s sharp edge. The curaçao adds a bit of orange flavor along with the blue, since it’s an orange liqueur underneath the dye. If you’ve got a bottle of the blue stuff hanging around from summer, our page on what to mix with blue curaçao has plenty more uses.

Why red and blue sometimes make brown

Here’s what happened in our kitchen. Drink colors work by taking light away, not adding it. Each colored ingredient soaks up some wavelengths and lets the rest pass through to your eye.

Blue curaçao’s dye absorbs mostly orange and red light, so what gets through looks blue. Cranberry juice gets its color from anthocyanins, the same pigments in red cabbage and blueberries, and those absorb mostly green light, so what gets through looks red. Put them in one glass and the only light that survives both is a band of violet-blue plus a little deep red. That’s purple.

Now add something yellow or orange. Orange juice, a yellowish bottled sour mix, even a heavy pour of a golden triple sec. Yellow ingredients absorb blue light. Suddenly the glass is soaking up red, green and blue all at once, and very little of anything makes it out. Your eye reads that as brown, or a murky grayish olive if the blue is winning.

So the fixes are simple:

Use a sour mix that’s pale, or swap in fresh lemon juice and a little simple syrup. Lemon juice is nearly colorless.
Keep the cranberry generous. Roughly four parts cranberry to one part blue curaçao keeps it on the purple side.
Add the curaçao last, a little at a time, and stop when the glass turns violet. You can always add more blue. You can’t take it back out.
Buy plain cranberry juice cocktail, which is a clear ruby red. Some cranberry blends lean orange or pink, and those drag the color off.

The Purple Rain shot

The shot drops the gin and the fizz. The Purple Rain Shot is vodka, cranberry juice and blue curaçao, shaken hard and strained. We like 3/4 oz vodka, 3/4 oz cranberry and a scant 1/2 oz curaçao for a two-ounce double that we split between two glasses. It’s tart enough to taste clean, and the color looks even more dramatic in a small clear glass under the porch lights.

If you’re planning a whole tray of colorful shots for a Halloween night, our roundups of blue shots and pink shots will help you build a rainbow.

A Purple Rain pitcher for a party

For a crowd, we skip the shaking and batch it in a big pitcher. Multiply the single recipe by eight: 12 oz gin, 16 oz cranberry juice, 8 oz sweet and sour (or 4 oz fresh lemon and 4 oz simple syrup), and 4 oz blue curaçao. Stir it together and chill for an hour. Don’t add ice to the pitcher itself, because melting ice will water it down long before the party winds up.

When guests arrive, fill tall glasses with ice, pour the mix about two-thirds of the way, and let everyone top their own with soda water. That keeps the fizz fresh in every glass instead of going flat in the pitcher. Toss in a handful of fresh cranberries for color. They bob around near the top and look festive with almost no effort.

Want a sweeter option beside it? The Purple Cool Aid runs on the same color logic with vodka, cranberry, 7-Up and blue curaçao, with lemon-lime soda doing the work that sour mix does in the original. Kids-table colors, grown-up pour.

The Top Shelf version

Then there’s the Top Shelf Purple Rain (Motor City), which barely resembles the original. It takes premium rum, tequila, gin and vodka, adds triple sec and Cointreau, then sweet and sour, and gets its purple from Chambord instead of the cranberry-and-curaçao trick. If that lineup sounds like a Long Island Iced Tea, you’re right. Pour it small, and keep the sour mix pale for the same color reasons as above.

A few more purple drinks

Once we had cranberry and blue curaçao out on the counter, a few relatives came along easily. The Purple Midnight swaps in silver tequila. The Purple Lamborghini Martini adds a little grenadine to vodka, cranberry and curaçao. And the Purple Hooter skips the curaçao altogether, getting its color from Chambord with vodka and 7-Up.
