Substance Diner, the popular vegan food truck that folks saw stationed at MotoSonora Brewing for a couple of years, moved to Screwbean Brewing in January of this year.
So, in December, the restaurant on wheels is ready to roll on and depart from its post at 103 N. Park Ave. #101.

“The food truck is leaving Screwbean Brewing and will no longer be operating on a daily basis there,” said Karl Poechlauer, owner of Substance Diner. “I am very grateful to them for hosting me this year, and now it is time for something… completely different.”
Poechlauer told his fans to keep an eye out for updates on future appearances at local events, meaning there are no plans to park at any one spot long-term.
“I have not made any menu changes other than shrinking it down to a size more conducive to a sporadic, pop-up schedule,” he added. “So, yeah, still 100% vegan.”
In the meantime, make sure to come out to Screwbean Brewing before the end of November to grab your favorite Substance bites. Also, there’s a chance Poechlauer may leave the brewery sooner if he sells out of product.
“Closed on Wednesdays, Closed Thanksgiving, Closed Black Friday, and then maybe open the following Saturday/Sunday,” he said. “Don’t delay, get your Substance today!”
For the remainder of the month, Substance Diner will be parked at Screwbean Brewing Company located at 103 N. Park Ave. For more information, follow Substance Diner on Instagram.

More about MattAt a very young age, Matt Sterner was gifted with the artistic ability to masterfully roll a burrito to the highest of standards, but the wrapped medley of delicious innards wasn’t his first love. Matt’s first true love was a combination of reading, writing, and creating. He grew up reading comics, the ingredients list of his shampoo and conditioner bottles, choose-your-own-adventure books, and the Scrabble dictionary — something he found useful when challenging his grandmother to a game.
He attended college at New Mexico State University and graduated with a degree in Digital Filmmaking. One of his favorite classes was screenwriting because he became responsible for the story’s birth before it came to life on-screen. After school, Matt took on numerous positions at a local television station in Tucson. From dealing out stories about heartbreak to producing “fluffier” content for a lifestyle broadcast, he learned what it takes to adapt to the many emotions the world of media can stir. Since 2017, Matt has dabbled in the culinary world of Tucson as well as San Diego, California from time to time.
