Norwegians are the largest consumers of coffee in the world, leaving the Italians and their dainty espressos in the dust. Oslo Coffee Roasters offers grumpy Brooklynites a potent taste of Scandinavia. Opened in 2003, owners JD and Kathy Merget are dedicated to sourcing the best coffee worldwide and pride themselves on only buying the beans that are sustainably and ethically produced. With two locations in Williamsburg and an outpost in Yorkville, Oslo is making its mark among selective coffee drinkers.
