April seems to have got off to a challenging coffee grinder month. This morning I got a call to check out the setting on a coffee grinder which had been installed as a temporary measure.
It's not until you handle espresso coffee on a daily basis that you appreciate how many reasons there are as to why it might not extract the flavour as well as you might expect. For the purposes of this blog I'm assuming water temperature, the pressure of the machine and the freshness of the coffee are all perfect (big assumptions I know!). Here I want to focus on the grind of the coffee.
