It might sound crazy but sharks have been around longer than trees! Yes, the earliest recorded species to be classified as a tree lived around 350 million years ago. Sharks however, have existed for 400 million years and survived four global mass extinctions.
3 Coffee Facts
Why are commercial espresso machines so expensive even though some home machines have fancier features? The main reason is build quality — these machines are built to make 50, 100, 500+ shots a day, everyday for years, so the internal components are way more robust. Even a small cafe will bust out more shots in a week than you do at home in a year.
You may have noticed that single shot baskets (used for ~7-10g shots) look very odd compared to larger capacity baskets. The taper and concentration of holes in a smaller area help increase the bed depth and allow pressures to reach 6-9bars without extreme channeling.
Many espresso machines have a tray on top to hold cups but did you know they serve a dual purpose by also warming the cups using the heat from the boilers?
