How specialty coffee woke up to water’s role in flavour

How specialty coffee woke up to water’s role in flavour

For the longest time, the coffee community only cared about water’s impact ruining espresso machine boilers and kettles. But what about water’s impact on coffee flavour?

In this episode, I tell the story of how the specialty coffee community came to understand water chemistry: the pioneering work of the computational chemist Christopher Hendon and British roaster Maxwell Colonna-Dashwood, the genesis of the SCA’s Water Quality Handbook, and where we are today understanding the impact of minerals on our water.

I strongly recommend listening to the two episodes before this one first Getting great water for coffee, step-by-step & The two ingredients in water that ruin your coffee, and the ancient story behind them
