Jens Knoop has spent about 10,000 hours – that’s 1,000 hours a year over the last decade – perfecting his chocolate drinks, blending different strengths with milk, fruit, roots and spices.

He calls the process “Knoopology” and is still discovering new flavour combinations.

As a keynote speaker, Jens will talk about the joys and pitfalls of turning something you love into a successful business, what’s next for the company – and what his own favourite flavour of chocolate is.
