It took Jeff “Beachbum” Berry over a decade to track down the original recipe for the Zombie. The faux-tropical drink was created in 1934 by Ernest Gantt, who founded the world’s first tiki bar, Don the Beachcomber, in Los Angeles. Later, he legally renamed himself Donn Beach.

A potent mix of three rums, lime and grapefruit juices, as well as assorted syrups and bitters — nine ingredients in all (recipe below) — the Zombie was a closely guarded secret. Beach famously encoded the bottles at his bar so employees couldn’t give away confidential combination.

In 2005, the code was cracked when a notebook containing the recipe was found in the pocket of an old shirt owned by Dick Santiago, headwaiter at Don the Beachcomber. Santiago’s daughter relayed it to Berry, who published the recipe in his 2007 book, “Beachbum Berry’s Sippin’ Safari.”

Like many tiki drinks, even with the recipe, the Zombie remains a challenging drink to master.

“People will try different recipes at home and then say, ‘Why didn’t the Zombie come out as well as it could, or should?’” Berry said. He personally sampled a lot of “godawful” versions in the 1980s and ’90s that tasted like “Hawaiian Punch with a lot of rum in it.” It left him wondering why the drink had once enjoyed such popularity — until he pieced together the original recipe.

His solution: Hamilton Rum’s Beachbum Berry’s Zombie Blend, which combines three carefully sourced rums in one bottle. Expected to be commercially available in August, it features Berry’s own zombified mug on the label. It was created with an eye toward home bartenders who might be stymied by sourcing multiple bottles, but it might also help busy bars seeking a shortcut in order to measure and pour one rum, instead of three.

Tiki secrets

Each rum in a tropical drink contributes something specific, a secret Donn Beach knew well. In his classic Zombie, aged Jamaican rum offers fruit and funk, overproof Demerara rum gives bold brown sugar tones and a wallop of alcohol, and the neutral canvas of gold Puerto Rican rum ties it all together in a 1.5-1-1.5 ratio, respectively. In total, Beach’s version called for a whopping 4 ounces of alcohol — one reason it was one of the most popular drinks of the 1930s.

“After Prohibition, it was like a punch in the face to the Anti-Saloon League,” Berry said. “It’s such a strong drink, Donn would serve only two to a customer. That added added to the mystique.”

The Zombie Rum concept first came about in 2019, at the tail end of the annual Tales of the Cocktail conference in New Orleans, when Ed Hamilton, proprietor of Hamilton Rum, settled in at Berry’s bar, Latitude 29, and asked him what he needed.

As Berry recalled, he motioned to a bartender preparing a round of Zombies, the second most popular drink on the menu, and said: “Nobody’s done a Zombie rum blend.”

Reanimating the Zombie

Spirits aren’t typically combined and bottled with a single cocktail in mind, but another tiki icon, “Trader Vic” Bergeron, provided a template. “In the 1980s, Trader Vic had a Navy Grog rum and a Mai Tai rum, so you didn’t have to go out and buy a bunch of rums. You could just buy the bottle,” Berry said. “I thought it was genius, and nobody was doing it.”

The two workshopped the Zombie blend during the pandemic, with Hamilton sourcing and mixing distillates and sending them to Berry for tasting and feedback, a process repeated multiple times. “We traded back and forth until we found a blend we liked,” Berry said.

The final mix incorporates eight different distillates: A blend of Jamaican rums of various ages, sourced from Worthy Park; a blend of at least three older Guyana rums aged two to five years, sourced from Demerara Distillers; and a relatively light, column-stilled Trinidad rum standing in for the Puerto Rican component. (“Before 1960, Puerto Rican rums had more character than they do today,” Hamilton said of that switch.)

Prior to the pandemic, tropical drinks and tiki bars were on the rise, and their celebratory aspect persists. In 2020, rum sales grew 5.9%, or $138 million, to $2.4 billion, according to the Distilled Spirits Council of the United States, with sales particularly robust in the premium and high-end-premium categories (rising 7.6% and 8.7%, respectively).

Potent punch

Berry described the liquid as possessing “the smoke and charred wood” of a Demerara rum, with “fruitiness, molasses-y-ness” contributed by Jamaican rum, and the milder Trinidad rum serving to “cut the intensity” and smooth it all out. The end result is complex, yielding “teasingly elusive layers of flavors” that serve to elevate the Zombie, much as it did in Donn Beach’s day. By collapsing together three rums into one ingredient, for cocktail enthusiasts “it’s like control-freaking their drinks at home.”

One key difference: Only 2 ounces of the Zombie blend are needed to make the drink. It’s still high-octane, clocking in at 119 proof (59% alcohol by volume), but it won’t knock you off your chair, unlike Beach’s original blueprint (4 ounces of a 49% ABV rum blend). We’ll save breaking out the calculator — that’s almost 40% less alcohol than the original version of the drink. (Berry tweaked his Zombie recipe slightly to compensate for the reduced volume of liquid.) Compared to the cost of three or more rum bottles, the Zombie Blend is anticipated to sell for under $40, though that’s subject to markups by distributors and retailers.

“Of course, it can’t be just a one-trick pony,” Berry said, noting that the blend also works in drinks such as the Jet Pilot (“it’s a Zombie without the grenadine”), the Cobra’s Fang, and the Tortuga.

Looking ahead, Berry and Hamilton already are collaborating on a Navy Grog rum, an overproof blend to fill out another Beachcomber drink — this one a 1941 concoction made with lime and grapefruit juices, honey syrup and soda water, traditionally served with shaved ice shaped into a cone. The Navy Grog blend is expected to be available later this year.

However, this is as close as tropical drink fans will get to convenience. Don’t expect to find a canned or bottled ready-to-drink Zombie on the shelf. Berry considered it, but decided that a tiki drink without fresh lime is unthinkable.

“I’m not going to destroy what makes the drink great by putting it all together. It would need preservatives and God knows what for shelf stability,” Berry said. “You have to draw the line somewhere.”
