I recently went on a training session at Brew Lab.
If you live in Edinburgh then I really recommend you get some friends together and book a session in their training lab. It was great and opened my eyes as to how complicated coffee can get.
However, our trainer was telling us about how she had had to change the way she presses coffee down into the espresso machine.
Note her alignment here on the left, her wrist is directly above her hand and her forearm directly above that. Nice straight alignment of the joints. The only way is could be better is if it was lower and her whole arm was straight below her shoulder joint – not a very practical way to make coffee!
Why had she gone to this method?
She had managed to damage her joints by doing it out of alignment and had spent ages with a splint on her wrist.
A little anatomical knowledge can always make things better – even your coffee!
