Flavor Characteristics
- These are the many unique flavors that you can taste in a cup of
Espresso or coffee.
Five Basic drinks
1. Espresso: See the SCAA definitions above
2. Café Crema: This is a long espresso. Instead of turning off the pump when you
get to a proper single shot or double shot, keep the pump ruining until you get a
full cup of coffee. The actual volume of the café crema can be whatever we
choose. The more water through the coffee, the weaker it is. 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 one-third espresso and two-thirds steamed milk.
5. Café Cappuccino: Equal amounts 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 take
more water through than a proper shot calls for, you extract some of the undesirable
flavors, which will make it bitter. When brewing a shot, you can see how 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. This is because a Café Americano is a proper shot of espresso mixed with
hot water. The coffee is not over extracted. Because of the three types of coffee you can
make, espresso, café crema and Café Americano, you may find that you will never need a
drip machine again. One of the best full cups of coffee you can ever have is a Café
Americano.
