90 is the new 70: A High Percentage Dark Craft Chocolate Tasting – London Craft Chocolate Fair 2026

About the event

Demand for higher cocoa content bars is rising, with more and more people looking beyond the classic 70% for higher cocoa content. But are all dark chocolates made equal? We would argue that, the higher the cocoa content, the more the cocoa itself matters. So what should you look for in a dark chocolate bar? How does a chocolate maker approach a 90% versus a 70%?

In this tasting, you’ll try a range of chocolates with between 80-100% cocoa content. Challenge yourself to go darker and see if you can find a new favourite. Spencer Hyman, co-Founder of Cocoa Runners will lead the session, joined by a craft chocolate maker to share their experience of crafting a higher percentage chocolate bar.

This tasting is part of the London Craft Chocolate Fair 2026. See the full line-up of talks and tastings here. Your ticket will also grant you free access to the Chocolate Makers Market.
