Some coffee history for you.
This is the one of the first ever publicly posted photos of a chopped portafilter shot pull, in action. It was posted to CoffeeGeek's forums back in 2005, within 2 days of the "design concept" idea for drilling the bottom of a PF off to expose the filter basket being posted to a now defunct coffee forum. Shot taken at Elysian Coffee, in Vancouver.
No one had seen this before this photo.
