Coffeestamp

Coffeestamp was created by brothers Patrick and Spencer Clapp in 2018 as a micro-roastery. Its original location has since grown to a full service coffee bar in the Fox Park neighborhood of Saint Louis, Missouri, with a new location right here on Wash Ave. Coffeestamp’s mission is simple—deliver the most delicious coffee possible. To do this, they source only the finest coffee beans from around the world. Coffeestamp believes coffee can be roasted in countless ways that make it worthy of writing home about, but they know it can fail every time if the coffee bean wasn’t grown and picked with love.

The Wash Ave café is at 1228 Washington Ave in the historic Cordovan on the Park building (formerly the Rudman Building). The Clapp brothers are originally from Honduras, and Coffeestamp’s beans come from La Finca Alondra San Vicente, the farm of lifelong friend Miguel Giron. Sauce Magazine reported in May 2026 that the downtown menu includes: coffee, beans, tea, kombucha, empanadas, sandwiches, pastries and breakfast. Read the Sauce Magazine story.
