Kwik Trip has long been known for its Karuba coffee offering. A few years back, the regional c-store stalwart invested in a fleet of self-serve, touchscreen beverage machines that grind espresso beans and steam fresh milk to order. The machines offer the chain’s Karuba Gold drinks in Americano, latte, iced latte, macchiato, cappuccino, mocha and iced mocha varieties. Guests can also customize their beverages with extra sweetener and flavored syrups using prompts on the touchscreen.
