Discourse Coffee | Radio Milwaukee

Discourse Coffee is a Milwaukee-based craft coffee workshop founded in 2017 by Ryan Castelaz, originally launched in Sister Bay on the Door County peninsula before expanding to multiple Milwaukee locations. The Radio Milwaukee location opened in March 2024 at 158 S. Barclay Street in Walker’s Point, operating as an all-day café within the nonprofit Radio Milwaukee studios, offering craft espresso drinks, pour-overs, experimental coffee cocktails, seasonal food, and a curated vinyl listening experience. The space also serves as a community gathering hub for Radio Milwaukee events, including live music programming and private events, deepening the shared mission of both organizations around music, storytelling, and community connection.
