This year, National Rum Day isn’t just for rum lovers. Todd Thrasher and his team at The Wharf’s Potomac Distilling Company have released Thrasher’s Green Spiced Rum: a rum with flavors reminiscent of an English gin.

The Green Spiced Rum is available behind the bar, and curious imbibers can sample the spirit for free today from 3 p.m.-6:30 pm at Potomac Distilling’s sister bar, Tiki TNT, which opened in December.

According to Thrasher, he developed a taste for rum and tonics “during my days as a dive master traveling through the South Pacific.” When he set out to open Potomac Distilling, Thrasher sent himself to Moonshine University in Louisville, Kentucky, to learn the art and science behind distilling. From the beginning, one of his goals was to create the perfect rum to complement tonic. Says Thrasher, “Green Spiced Rum really acts like gin, but for rum lovers.”

At Potomac Distilling, Thrasher likes being experimental. The Green Spiced Rum makes three products that Potomac Distilling has produced so far, along with a spiced rum and a white rum. “I like to think that I’m bringing a distinct English Caribbean-style of rum to America, a country that has primarily relied on rum to be imported from other countries,” he says. “What I learned was that in order to do craft—to be artisanal—you really should take some chances and try different things.”

After some experimentation with botanicals from his own garden, he and his team settled on the basic recipe for Green Spiced Rum (which, yes, does have a have a slight green coloration from all the herbs involved). Production began in the spring.

In the end, the final product is distilled from the same sugars and molasses as traditional rums and Thrasher’s White Rum and Spiced Rum, but flavored with lemon verbena, lemongrass, lemon balm, mint, lime peel, and cardamom like a gin would be. Notably absent from the blend is juniper, a traditional gin botanical responsible for gin’s sometimes Christmas tree-like flavor. Thrasher purposefully steered clear of juniper for his gin-like rum because of how polarizing that flavor can be. (That’s also why he gave it the vague name Green Spiced Rum—to not scare away the gin-averse).

The herbs are largely grown in the rooftop garden on top of Tiki TNT. At the bar, the Green Spiced Rum is used, of course, for rum and tonics, but also to add a unique twist to a whole host of traditional rum drinks like mojitos.

“[I] often hear people say that they don’t like rum because it has so much sugar in it or that they don’t like rum-based cocktails because they are crazy sweet,” Thrasher says. “That just isn’t true. I plan to educate my guests about the versatility, complexity, and diversity of rum.”

Despite the slight green twinge, Green Spiced Rum doesn’t taste like it looks. It’s a lot more spice-forward and complex than its largely clear coloring would lead you to believe, especially next to Thrasher’s much more traditional White Rum. At first taste, it comes off like a cardamom-forward rum, but it finishes just like a typical gin.

This first run of Green Spiced Rum is just 700 bottles and more than half of that will be used at Tiki TNT. Each new batch the team produces will be more finely honed with slightly different flavors, and—if they get things right—a little bit greener in color too.

You can try Green Spiced Rum at Tiki TNT or bring home a 750 mL bottle for $27 by visiting Tiki or giving them a call. They hope to soon launch online sales as well. If you do get your own bottle, Thrasher recommends giving the rum and tonic a try, and says you can also use it in cocktails as a mixing spirit. Either way, to him “it’s like vacation in a glass.”

Tiki TNT will offer free tastings of Thrasher’s rum Friday, 3 p.m.-6:30 p.m. Food and drink specials run all day.
