Julian Giraldo

The current Head Distiller of Giant Texas Distillers of Houston, Texas, is Julian Giraldo. Giraldo was born in Colombia in June of 1981. His move to the United States and his rapid rise within the industrial and distilling circles of south Texas have been described as a true embodiment of the American dream. Giraldo's earliest exposure to professional flavor tracking and sensory evaluation happened during his time managing coffee production. He spent years overseeing coffee-side operations and working intimately with bean roasting and blending profiles for the de Aldecoa family’s coffee-producing company. He later reflected that this early training in nosing, tasting, and tracking distinct coffee flavor profiles perfectly prepared him for the sensory demands of aging spirits.

Giraldo joined Cadeco coffee producers in 2007, years before the parent company began producing distilled spirits. The de Aldecoa family had purchased Houston’s former Uncle Ben’s rice-processing facility on Clinton Drive in 1998 and converted the industrial property into a coffee-manufacturing plant. It was there that Giraldo accumulated experience in food manufacturing, production, and product development there, ultimately overseeing part of the coffee operation. Working with coffee also sharpened his awareness of aroma and flavor, skills that later transferred naturally to the evaluation of fermenting grain, new distillate, and mature whiskey. Geraldo also first built his industrial leadership experience there, as operations manager, a role he held until 2017. He gained extensive background in food manufacturing, raw material intake, and large-scale operations, which paved the way for his transition into spirits. When Cadeco's parent organizations moved toward constructing a massive grain-to-glass spirits distillery, Giraldo bridged his technical systems engineering background with a newfound passion for fermentation. He eventually transitioned fully into his role as Head Distiller in January 2017 under the mentorship of legendary industry master David Pickerell. Earlier, Giraldo had earned a bachelor’s degree in computer science and systems engineering, later qualifying as a Six Sigma Green Belt as well. That technical foundation eventually became central to his work at Giant Texas.

The company itself had begun exploring distilled spirits in 2014 under the name Buffalo Bayou Distilleries. It received its federal distilled-spirits authorization and Texas distiller’s permit during 2014 and 2015, and Gulf Coast Distillers became its operating name in 2015. Giraldo participated in the distillery’s development from its beginning, helping transform part of an established food-production facility into a large-scale spirits operation. Three pot stills, a mash tun, and fermenters were installed during 2016 and 2017, creating the production system through which Texas grain could be mashed, fermented, distilled, barreled, matured, and bottled in Houston.

Geraldo’s systems-engineering background suited the demands of the new operation. Whiskey production requires the distiller to control many connected variables: grain preparation, water, mash temperature, yeast activity, fermentation time, distillation rate, proof, barrel entry, warehouse conditions, and final blending. Giraldo applied process efficiency and quality standards throughout that sequence while developing the practical judgment needed at the still. By 2018, the distillery had filled its 1,000th barrel, an important measure of how quickly the former coffee-centered operation had developed into a substantial whiskey producer.

The heart of Giraldo’s work became Giant Texas Bourbon, a grain-to-glass whiskey made from Texas ingredients. Its established mash bill contained 75 percent corn, 21 percent rye, and 4 percent malted barley. The distillery matured the bourbon in new American oak barrels with a No. 4 char, allowing Houston’s hot days and cool, humid nights to drive repeated interaction between whiskey and wood. The original whiskey was sold at several proofs, including 80, 91, and 95 proof, and the 95-proof release relied on barrels Giraldo selected as the strongest examples in the warehouses—the especially successful barrels commonly called “honey barrels.”

Recognition followed the expansion of production. Giant Texas Bourbon 95 Pot Still received a silver medal at the 2019 San Francisco World Spirits Competition. An independent 2018 appraisal in Forbes scored the 80-proof bourbon 92 points and praised its balance, smoothness, and value. Those results placed Giraldo’s work within the growing Texas whiskey movement while demonstrating that a large industrial facility could produce carefully-managed pot-distilled bourbon.

In early 2022, the company relaunched Giant Texas Bourbon at 100 proof with revised packaging and a more unified brand identity. Giant Texas 100 Straight Bourbon was distilled in the company’s large pot still from Texas grain and aged for at least three years. The stronger bottling allowed the whiskey to retain more of the structure supplied by its rye-heavy bourbon mash bill and barrel maturation. Giant subsequently added a cask-strength straight rye made from Texas-grown grain, extending Giraldo’s work from the original bourbon into a broader range of locally produced American whiskeys.

Outside the distillery, Giraldo enjoys camping, mountain biking, stunt-kite flying, and traveling with his family to visit wineries and distilleries. His documented career nevertheless presents a clear progression: systems engineering led to food production, coffee manufacturing cultivated an understanding of flavor, and the construction of a Houston distillery gave him the opportunity to unite technical discipline with sensory judgment. Giraldo’s contribution to Giant Texas rests in that union. He helped take the spirits project from equipment installation and experimental production to its first thousand barrels, award-winning bourbon, higher-proof straight whiskey, and cask-strength rye. The old rice plant on Clinton Drive now houses a distillery capable of handling grain, fermentation, distillation, maturation, bottling, and contract production on a substantial scale. At the center of its whiskey-making operation, Giraldo converted years of manufacturing experience and disciplined process control into bourbon and rye that are harvested, distilled, matured, and bottled in Texas.
