JD and Kathy Merget moved from a Chinatown apartment to Williamsburg to start a coffee business, and Oslo Coffee opened in 2003. They roast their own coffee on a Probat roaster.
The four shops sit in Williamsburg (two), Yorkville on East 75th Street and the West Village on West 10th Street. Since 2024 they have served Nicaragua Washed Bourbon from Jorge Lagos and his wife Entizar at Finca Santa Teresa in Dipilto.
