We’re glad you asked. You can improve the quality of your espresso by practicing your technique with the following guidelines in mind. The most important elements in espresso preparation are the grind, dose, leveling, distribution, and tamping. Perfecting how you do these will allow you to make great coffee every time.

Felix recommends a 1:2 brew ratio for espresso.

• For a triple basket: for 20 grams of ground beans in, you want to get about 40 grams of liquid espresso out. If you do not have a scale to weigh your input and output, it translates into 2.0 oz of liquid, including the crema.
• For a double basket: for 18 grams of ground beans in, you want to get about 36 grams of liquid espresso out. If you do not have a scale to weigh your input and output, it translates into 1.5 oz of liquid, including the crema.
• The best shots of espresso are pulled in a range within 25-30 seconds from when then pump starts, with espresso dropping from the portafilter after 5-7 seconds.
• Grind your coffee fresh and be as efficient as possible. Don’t let ground coffee sit in the portafilter, and don’t let the portafilter sit in the group head loaded with espresso grounds before brewing. Coffee stales very quickly once it’s ground.
• Pre-heat your shot glasses, demitasse or mug with hot water before you begin grinding the coffee and preparing the shot.
  

  The Grind

  The basic premise of dialing in your grinder is to ensure that your 2.0 brew ratio occurs within 25-30 seconds after your pump starts.

  Dose

  Felix recommends a dose of 18 grams of coffee when using a double basket.

  Dialing in your shots and grinder

  No worries…There is a 0% chance this is perfect the first time.

      Problem and Remedy

• 30g of liquid came out before 25 seconds (Too fast) > Make the grind finer
• 30g took more than 30 seconds (Too slow) > Make grind coarser
• Espresso pulls in target times but tastes harsh > Make the grind coarser and increase the dose

       Pouring

As reference when pouring the espresso  the liquid should come out of the
portafilter like a string of spaghetti.
