Coffee Basics: How To Brew The Perfect Espresso
Before You Begin
Several key factors will influence the quality of the drinks that you serve.
The cleanliness of the machine will directly affect the taste of your coffee.
Follow these simple rules to maintain cleanliness:
- Wipe the steam arm after every use
- Back flush each group head a minimum of 3 times daily
- Clean each group head with Mulclean daily
- Clean the bean hopper once a week
Espresso should be served hot! It is important to keep the group handles in the group heads at all times. Handles should be left on the drip tray when not in use.
Oxygen is the enemy of fresh coffee. Pour no more beans in the hopper than you need for today. Don’t grind more beans than you need for the next hour. Serve it fresh!
Decaf coffee use the correct 7g scoop; one level scoop for a single, two level scoops for a double.
The Core Ingredients Of The Perfect Espresso
The international standard for espresso extraction is:
- 7 grams of ground coffee dosed into the correct group handle
- The coffee should be tamped using 20 – 40 pounds of pressure per square inch
- Brewed using water at 90°C
- Under pressure of 131 pounds per square inch
- With an extraction time of 20 – 30 seconds
The Perfect Espresso
Step One: Choose the correct group handle for the drink you plan to make.
Use single handle for: Single Espresso, Cappuccino, Caffe Latte, Cafe Mocha.
Step Two: The taste of your coffee will be directly affected by the amount of coffee you dispense into the group handle.
Single Handle: One complete pull – No more No less.
Double Handle: Two complete pulls – No more No less.
Step Three: Tamp the coffee. Hold the group handle in your weaker hand, tamp with your writing hand. As you tamp give the handle a good hard twist left to right to ensure a solid pack.
Step Four: Wipe the excess grounds from the rim of the filter. Note: this will ensure that you don’t have coffee grounds build up on the rubber seal in the brewing head. Over time this build up will cause grounds to leak into the coffee drink you are preparing.
Step Five: Brew the espresso into a demitasse.
