Why we love this haunted swamp water drink

The original swamp water cocktail was created in the 1970s by a marketing committee to get the younger crowd to drink Chartreuse. It was basically just pineapple juice and the herbal liqueur, but you needed a lot of Chartreuse to make it – like 2 1/2 ounces per drink.

Now that it’s hard to find, I don’t want to waste a single drop of it, so I reimagined the swap water cocktail and elevated it to today’s cocktail culture standards by pairing it with a homemade green juice and a little gin.

To make this a little spookier, and much more fitting for Halloween, I muddied up the cocktail with a hit of matcha powder and served it with dry ice to create a beautifully spooky effect.

How to make a swamp water cocktail

Make the green juice. Combine the juice ingredients in a blender or food processor and blend until smooth. Then, strain the juice using a fine mesh strainer. You can save the pulp for smoothies, or you can discard it – totally up to you.

Once the juice is made, you can go ahead and make your cocktails or refrigerate it until you’re ready to drink.

Mix the drink. Fill a cocktail shaker with ice and add the green juice, gin, Chartreuse and simple syrup. Shake until cold.

Serve with dry ice. Drop a small (1/4″) piece of dry ice into your glass and strain the cocktail over it. Be sure to choose a glass that will accommodate extra space above your cocktail. This helps the dry ice smoke collect and creates a more intense fog effect.

Be sure to allow the dry ice to completely dissipate before consuming your cocktail.

To serve without dry ice, simply shake the cocktail and strain into an short glass filled with ice. Garnish with fresh mint.
