Key ideas in Starting a Coffee Cart

  • Keeping coffee weight in and liquid espresso out fixed establishes your base brew ratio
  • Changing grind size while liquid yield is drifting makes it impossible to isolate flavor problems on a cart
  • A consistent brew ratio ensures drinks taste uniform from the first morning customer to the last
  • Shots that pour too quickly under-extract, tasting sour and weak, requiring a finer grind to slow the water down
  • Shots that choke the machine over-extract, tasting dry and bitter, requiring a coarser grind
  • Shot duration provides an immediate visual cue for cart baristas during a busy line
  • Outdoor air temperature and moisture shifts cause coffee beans in the hopper to swell or dry out
  • A morning setting on an outdoor cart will often run too fast or choke by midday as the weather warms up
  • Mobile cart baristas must make subtle micro-adjustments to the grinder throughout outdoor service
  • Weighing a fixed dose in the portafilter comes before pulling water through the coffee
  • Stopping the shot at target liquid weight reveals the actual flow time
  • Tasting confirms the shot is ready to serve paying cart customers before opening the window
  • Batch brewers and pour-overs use coarser grinds because gravity water contact takes minutes rather than 30 seconds of high-pressure espresso
  • Drip coffee that drains too fast produces under-extracted, sour cups just like fast espresso
  • Finely ground coffee will choke a batch filter basket and extract harsh, bitter flavors
  • Keeping the grinder, group head, and knockbox within an arm's reach triangle lets the barista work without taking foot steps
