165: Bret Kollman Baker of Urban Artifact is Fastidious About Quick Sour Beers

Scaling sour beer production requires a shift from traditional boil-kettle souring to dedicated, temperature-controlled fermentation vessels using pure Lactobacillus cultures. This approach ensures consistency and prevents off-flavors, particularly when incorporating large volumes of fruit. Managing fruit additions involves precise temperature control during pasteurization to preserve aromatics and mitigate chemical reactions, such as the vinyl off-flavors caused by strawberry seeds. Beyond technical process, the perception of acidity and sweetness remains heavily influenced by branding and consumer expectations, which can be managed through descriptive labeling. Utilizing tools like pectinase enzymes and centrifugation further enhances product quality and yield, allowing breweries to maintain a sustainable, high-volume operation while focusing on a specific niche. Bret Kollman Baker, Chief of Brewing Operations at Urban Artifact, emphasizes that success stems from deep specialization and a commitment to both product quality and employee welfare.
