Basic Terms
Filter Basket: The stainless steel basket that holds the ground coffee. Most machines
come with a single and a double-shot filter.
Portafilter: The handle on that holds the filter basket.
Shower Screen: The part of the machine where the water exits the brew group. It
distributes the hot brewing water onto the coffee.
Brew Group: The part of the machine that holds the shower screen. The portafilter goes
into the brew group.
Drip Grate: The area you put the cups on when brewing.
Drip Tray: Catches any spilled coffee and is underneath the drip grate.
Extraction: When you brew coffee or espresso, you extract the flavors out of the coffee.
Flavor Characteristics: These are the many unique flavors that you can taste in a cup of
espresso or coffee.
Five Basic drinks
1. Espresso: Please refer to the SCAA definition.
2. Café Crema: This is a long espresso. Instead of turning off the pump when you
get to a proper single or double shot, keep the pump ruining until you get a full
cup of coffee. The actual volume of the café crema is up to you. The more water
you use, the weaker the coffee will be. A café crema would be classified as an
over extraction.
3. Café Americano: Brew a proper single or double shot and add hot water. This is
the best full cup of coffee that you can make.
4. Café Latte: Consists of 1/3 espresso and 2/3 steamed milk.
5. Cappuccino: Equal amount of espresso, steamed milk and frothed milk.
Extraction Information
Your Expobar machine is designed to brew a proper single or double shot according to
the Specialty Coffee Association of America’s (SCAA) definition. With a proper shot of
espresso, you extract the flavors out of the coffee that the roaster intended. If you run
more water through than a proper shot calls for, you will extract some undesirable
flavors, which will make the resulting espresso bitter.
When brewing a shot, you will notice that at the end of the extraction the flow gets lighter
in color. This lighter color is the sign of an over extraction and will cause the bitter
flavor. For this reason, a Cafe Americano will taste better than a Café Crema. A Café
Americano is a proper shot of espresso mixed with hot water. The coffee is not over
extracted. There are three types of coffee you can make with the Expobar Brewtus:
espresso, Café Crema and Café Americano. You may find that you will not ever need a
drip machine again.
