What Underground Coffee Roasters say
Klaus is a four bean blend of sweet Central American and full bodied rich Indonesian beans. Oozing with chocolate and rich caramel flavour, Klaus will linger on the palate inviting you for a second cup.
Bold. Smooth. Mysterious.
Klaus is a rich, four-bean blend inspired by complexity – in both flavour and story.
This carefully crafted blend combines sweet, high-altitude Central American beans with deep, full-bodied Indonesian origins, resulting in a cup that’s as intriguing as it is indulgent. Expect a luxurious flavour profile that oozes with dark chocolate and rich caramel, delivering a velvety mouthfeel and a lingering finish that keeps you coming back for more.
Klaus is versatile across all brew methods – excellent as espresso, divine in milk, and a standout for cold brew. It’s the coffee you reach for when you want both comfort and character in every cup.
The Story Behind the Name
Klaus Fuchs (1911–1988), the “Red Spy” of the Manhattan Project, was a theoretical physicist who passed atomic secrets to the Soviet Union during and after WWII. His controversial legacy – of intellect, complexity, and double lives – inspired this blend: one that’s deceptively smooth on the surface, yet deeply layered beneath.
Whether you savour the flavour or appreciate the layered history behind the name, Klaus is a blend that’s never forgettable.
