“It’s a beach-sipper you can have in the middle of a blizzard.”

That’s how Jesse Lauden, head bartender at Island Creek Oyster Bar, describes one of the Fenway seafood staple’s most interesting drinks: the Green Horizon.

The cocktail, which proudly bears the menu tagline “warm sun on calm water,” features punchy ingredients like Green Chartreuse, jalapeño-infused tequila, and a house-made fennel syrup alongside refreshing pineapple, lime, and cucumber. It debuted as a winter cocktail but proved popular enough to earn a spot on the summer list, too.

“We started off wanting to do a jalapeño-tequila cocktail with pineapple and Chartreuse,” Lauden says, “and then we took all of our secret weapons for making things refreshing, adding a little cucumber and a little chartreuse, adding the celery … almost like a kitchen sink-style cocktail.”

The end result drinks like a cold-weather sipper but tastes like a refreshing summertime cocktail. The spice kick from the tequila is measured, not overwhelming, allowing the herbaceous fennel and hint of Chartreuse to shine through. Celery adds a slightly savory note, and the sweetness of the pineapple, forming a little crema at the top of the drink, keeps it bright.

Key to the drink’s balance is the tequila’s relatively light jalapeño infusion: just 24 hours.

“We wanted to do an infusion where we got the light flavor and a little bit of heat,” Lauden says, “but then we could build the cocktail around it without the jalapeño flavor necessarily being a really strong component.”
