Meet Whiskey Del Bac’s New Master Distiller and Director of Operations

Whiskey Del Bac is raising a glass to one of its own.

The local distillery has promoted Mark A. Vierthaler to Master Distiller/Blender. But wait, that’s not all! He’s also the new Director of Distillery Operations — a title that still doesn’t quite capture all he does.

“There was not enough space on the business card for all that Mark does,” said Paul Winandy, CEO of Whiskey Del Bac. “So, we settled on Master Distiller/Blender and Director of Distillery Operations. It hardly seems sufficient but reflects his amazing contribution to our award-winning products and all that we do inside our Tucson home.”

Vierthaler joined the team as the head distiller in 2021, overseeing the daily production of Whiskey Del Bac’s American single malts.

“I’m incredibly humbled,” said Vierthaler.

Over the years, he’s helped increase the average rating of Whiskey Del Bac’s single malts to 90+ across all products. Plus, he created the 94-point-rated sourced-but-finished Sentinel of The Desert straight rye whiskey.

“Co-founders Stephen Paul and Amanda Paul have created and fostered a distillery that crafts whiskeys that tell a story of place,” said Vierthaler. “To be able to help write this love letter to the Sonoran Desert is one of my greatest honors.”

“Mark’s palate, his knowledge of all aspects of distilling, his passion for quality, and his incredible work ethic have been key to taking Whiskey Del Bac to another level,” said Stephen Paul, co-founder of the distillery.

As mentioned earlier, Vierthaler is also the Director of Distillery Operations, meaning he’s got his eye on the distillation and blending operations of the distillery, new product development, and the operations of all activities within the distillery including tours, tasting room, and events operations.

“His humanity and his understanding of our sense of place are critical to our ethos. I’m very proud to be on his team,” Stephen added.

With a new title (or two) and a deep passion for crafting whiskeys that reflect the Sonoran Desert, Vierthaler is set to continue shaping Whiskey Del Bac’s legacy — one barrel at a time.
