We talk about the three main ways espresso machines measure temperature and focus on the PID. We'll cover how a PID works, why it may not be so useful on a Heat Exchanger machine, and the importance of a group head design that works with the PID. Max also shows off a custom design he made for his Gaggia Paros.
How to improve your espresso without spending a fortune. This week on Bean Talk we share tips we've learned over the years.
This week we've drinking Burundi coffee from Artisan roaster - Amoret, based in Notting Hill Gate, London.
We also discuss why athletes like coffee so much, and the science behind the performance boost. Recent news stories have indicated that getting habituated to caffeine will reduce the impact of the stimulant before an event.
Yet recent scientific research largely debunks that. We discuss it on this week's Bean Talk.
