My bar at home is pretty uneven: We have our pick of a good 40 bottles of wine, some rum remnants, Grey Goose (a wedding leftover), and vermouth (from … college?). As much as I like cocktails, crafting anything fancier than a martini has always seemed like an expensive hassle to me.

Leave it to a man who mixes arugula, heirloom tomatoes, and Iberico ham into his drinks to change my mind. Nacional 27’s master mixologist Adam Seger shares his expertise during an hour-long “happy hour” class the third Thursday of every month. I was picturing a hands-on, sparsely attended session; instead, Seger set up shop behind the bar during March’s “Spice & Ice” class, with about 20 curious drinkers stationed on stools and a few tables.

He spent the first few minutes showering us with spice facts: those with higher oil content (like seeds and flower buds) have a greater intensity and are antioxidant-rich. And—lucky us—alcohol is a better carrier of antioxidants than water. Hibiscus tea, be gone!

Animated and passionate in his delivery, Seger then moved on to infusions. I had always been impressed by bars that advertise ginger-vodka and vanilla-bourbon in their drinks. Not anymore. They’re easy to make—super easy. Like, “throw some hibiscus flowers, cardamom, and ginger nibs in rum and let it sit” easy. It’s also snap to make a ramped-up simple syrup (for instance, add lemongrass and basil if you’re making cocktails to pair with Thai food).

Now ready to assemble, Seger instructed us to always follow the “two parts spirits, one part sweet, one part sour” formula, demonstrating with drink No. 1, a mojito made from rum, pomegranate juice, ginger-habanero syrup, and muddled mint and lime. A dazzlingly clear pink, it was dangerously refreshing—with a hint of heat. Drink No. 2, a mango-ginger-habanero daiquiri, came in a martini glass rimmed in a Christmas-y seven-spice blend. We left with a copy of the recipes (see below) so we could whip up the impressive drinks at home.

I left the session feeling completely satisfied with how I used my 5:30-6:30 p.m. hour—as well as with how I used my $20. When I first signed up for the class, that fee felt a little steep, but the full-sized mojito alone clocks in at $12 on Nacional’s menu. Throw in the daiquiri, Seger’s formidable knowledge, and the smattering of snacks passed about, and it’s more a steal than a deal. Plus, April and May’s classes are priced at just $15, which is good because I have some liquor shopping to do.
