Grunewald is one of four principals of Devil's Cask, along with Stella Amador, Jonathan Dietzel, and Fort Worth-based COO Chase Ament. All four are former roofers who teamed up after Grunewald had a light bulb moment while touring a Jameson Whiskey distillery in Ireland, according to the Star-Telegram's Brayden Garcia.
