Our founder Jens Knoops has had a strong relationship with chocolate since his childhood in rural Germany. In 2013, he decided to share his passion and opened the first Knoops store in Rye, East Sussex. Since then, Jens has gone on to open more Knoops stores, built a team of chocolate lovers around him, developed an at-home range of chocolate flakes, and even released a chocolate cookbook. The Knoops concept is based around our carefully curated percentage menu which offers chocolates to suit every taste and mood. We find joy in helping you to discover your perfect chocolate drink, and encourage experimentation with different % chocolates and flavours in a process we call ‘Knoopology’. This process is simple;choose your chocolate %, milk, and extra flavours like sea salt, orange zest or chilli to be made into a hot chocolate, milkshake or iced chocolate. With our app, you can get rewarded for your experimenting with Knoopology by collect points with every drink you buy in our stores.
