We all know that the people who make your cocktails can be right up there with your doctor, your shrink, your spiritual leader and your favorite podcast host when it comes to simple week-to-week survival. Sometimes they’re kind of all of those things rolled into one, except that they can also knock out a good drink – which might make them the most important people of all.

So when the best of them move on to new places, you want to know. Here’s a roundup of some of Dallas’ craft-cocktail peeps who’ve found new digs.

If you haven’t seen Eddie Eakin mixing things up at Bishop Arts’ Boulevardier lately, it’s for good reason: The buff barman has been busy readying beverage operations at soon-to-open Rapscallion, the new Lower Greenville venture from the folks behind Boulevardier.

With Eakin at the helm and one wall pretty much entirely devoted to bar space and storage, you know it’s going to be serious.

In Eakin’s absence, former Meddlesome Moth mixmaster Austin Millspaugh has stepped in to fill the void. The man who once incorporated foie gras into a cocktail is now overseeing Boulevardier’s bar program and is already in full tinker mode; if your tastes lean toward bitter, try his smoked Negroni with Fernet, thyme and Green Chartreuse. His ambitious alchemy should be interesting to watch as the year goes on.

Oak, in the Design District, is another place to put on your radar: The high-end restaurant has gotten double-barrel-serious about its cocktail program by bringing on both Michael Reith and James Slater, who between them produced three of my favorite cocktails of 2014.

One night, Reith was working his last night at the venerable Windmill Lounge in T-shirt and jeans, and the next he was pouring fancydranks in Oak’s signature white button-down shirt, black pants and tie. “I love it here,” he says. “It’s going to be a chance to shine again.”

Slater, formerly of Spoon, is likewise happy about the move; the dynamic duo have already put their formidable imprint on Oak’s cocktail menu with classic variations that include a killer Negroni and an Old Fashioned made with Old Tom gin. Though the two are different in style, their philosophies are simpatico, and the Panamanian-born Slater aims to inspire patrons to consider them as much of an accompaniment to dinner as wine.

“We’re going to change the bar program,” Slater says. “We’re like Batman and Robin.”

Meanwhile, it’s been six weeks since the much decorated Daniel Guillen left La Duni, for … well, for what no one was exactly sure – but after more than nine years with the operation, whose cocktail operations had become synonymous with his name, it was time to make a change.

It turns out there was a beast waiting to explode: The proudly Peruvian-born bartender has been unleashing his passions for Central and South American drink culture at places like Proof + Pantry and pop-up events – like next week’s cocktail dinner with Chef David Anthony Temple at Twenty Seven.

“Most bartenders focus on classic American cocktails, maybe a few from Europe,” Guillen says. “In my case, that doesn’t make sense. I would be one of many. So I thought, what can I bring to the table?” Look for more of the same while he and cocktail guru Sean Conner, he of the metroplex’s northern hinterlands, work on an upcoming project set to launch this fall.

At Blind Butcher, Ian Reilly is putting his own spin on things after joining the meat-forward establishment a couple months ago. “He’s the shit,” a departing and obviously happy patron says one evening. “He educates you and he makes you a badass drink.”

Reilly’s variation on the Old Fashioned, which he calls the Hubris, features whiskey with a hops-based syrup, because, “If I had to envision something that men here would want to drink – guys on the prowl, out celebrating, maybe going from beer to cocktails – what better way than to use hops as the sweetener?”

It’s one way that the bearded bar man is easing his way in at a place that has carved out a niche on busy Lower Greenville. “The formula here is working,” says Reilly, formerly of Bowl & Barrel and The People’s Last Stand. “I don’t want to stomp on that.”

Barter’s closing in January dispersed a number of souls to the winds – and one of them was the understated Creighten Brown, who has resurfaced at Tate’s in Uptown. (Juli Naida, as noted in 2014’s end-of-year post, has joined Mate Hartai’s team at Remedy.)

The talented tipple maker – whose Black Monk was also among my favorite cocktails last year – went from bar-back to bartender at Barter and is already hyped to be among Robbie Call’s team at Tate’s, along with Pro Contreras and Ryan Sanders. “The whole gang, man,” he says. “Good times, good times.”

Finally, Dallas recently bid farewell to two budding talents – Lauren Loiselle, who headed the bar program at Meddlesome Moth, and bartender Damon Bird of LARK at the Park. Both also figured prominently in my 2014 list but found themselves drawn to the Bay Area (and who can blame them?). “Two of our real good friends live in San Francisco,” Bird told me before they left. “We talked about it a long time and just decided to give it a go.”

Leaving Dallas was bittersweet, but both are excited about their new opportunities: Loiselle has joined the bar team at Café Du Nord, the new venture from the owners of Trick Dog. The team knows what it’s doing: Trick Dog is among four finalists for Best American Cocktail Bar at this year’s Tales of the Cocktail Spirited Awards, to be awarded next month. “I’m super stoked,” she says.

Bird, meanwhile, has nested at Mikkeller Bar, a beer-centric spot near Union Square featuring the best of brews from around the world. While he misses the craft-cocktail world, you can tell the easygoing drink-slinger has found his people. “This was my choice place,” he says.
