Grumpy Mule

You Need

  • Finely ground Grumpy Mule coffee. 2 heaped dessert spoonfuls (16-18g per cup - the amount depends on your machine)
  • Espresso machine
  • Scales
  • Timer
  • Cup

Note – for espresso machines you will need finely ground coffee. This coffee should be close to resembling a powder, but still coarse enough that it feels slightly gritty between your fingers, as opposed to a powder consistency.

Guide

  1. Weigh your desired amount of coffee. If you have a grinder, grind it to the correct grind size and place in the handle basket. We recommend 16-18g.
  2. Press your your coffee level (tamp). Being level helps get the most out of your espresso. Remove any excess coffee around the rim of the basket.
  3. Place scales and cup on the machine and zero them, start your machine (start extraction).
  4. Stop your extraction when your scales read between 38-45g of liquid espresso.
  5. Enjoy.

Extra nerdy-tip: A good total extraction time (hot water going through the coffee grinds) for Grumpy Mule coffee is around 27 seconds (+/-3) per shot. If it's too fat or slow, change your grind consistency.
