The New Era: Confluence Kombucha at The Fox Den

The biggest news for Confluence Kombucha fans is the successful relocation and expansion into a new, dedicated space. The move from The Grove neighborhood to a spacious facility in Fox Park marks a significant upgrade, allowing the team to fully realize their vision for a comprehensive fermentory and social club.

Location, Hours, and The Fox Den Concept

The new venue, affectionately named The Fox Den due to its proximity to Fox Park, is more than just a taproom; it's a multi-faceted experience center.

• Current Location (The Fox Den): 2501 S. Jefferson Ave., Suite 102, St. Louis, MO 63104 (Fox Park neighborhood)
• Concept: St. Louis' Premiere Fermentory & Ping Pong Club. The interior design leans into an animal theme, creating a cozy and unique atmosphere for socializing.
• Current Operating Hours: The Fox Den is open Thursday through Sunday from 11:00 AM to 7:00 PM, offering flights, take-away options, and packaged brews.
• Social Element: The inclusion of a dedicated Ping Pong Club area speaks to the owners' goal of creating a community hub—a place where people can gather, socialize, and enjoy non-alcoholic, health-focused beverages.

The Confluence team has leveraged the move to double down on their artisanal methods. Their kombucha is glass-fermented, a time-honored technique that many believe produces a cleaner, superior flavor profile compared to larger-scale industrial fermentation.

The GastroLab menu is specifically designed to complement the complex, acidic, and often herbal notes of the kombucha. It's a culinary philosophy rooted in health, minimizing common food triggers while maximizing flavor and gut health benefits.

  • Kimchi Tacos: A fusion dish that pairs the crunch and spice of fermented kimchi with fresh, savory fillings.
  • Kimchi Pancakes: A unique take on a savory pancake, offering a harmonious blend of fermented and fresh tastes.
