Precisia Coffee is dedicated to manufacturing precision temperature controlled home
espresso machines. It is widely recognized that proper brewing water temperature is
one of the most important factors affecting the taste of the espresso. If the water
temperature is too low, it will not completely extract the aroma from the coffee.
However, if the water temperature is too high, it will extract unwanted bitterness.
Experts believe that the brewing temperature for any particular blend of espresso beans
(optimum is typically between 196 F and 204 F) should be maintained within one degree
during the extraction process in order to produce the best tasting espresso. In addition,
each individual may have their own taste preferences of that coffee which can be
affected by the brewing water temperature. Most home espresso machines use a
simple snap action on-off thermostat as a means of controlling water temperature. This
can allow for a fluctuation of up to 40 degrees (Fahrenheit) in the brew water
temperature and is the primary reason why most espressos made in the home cannot
equal the taste of an espresso brewed in a commercial coffee cafe.
Precision Temperature Control
The Precisia SYL-100 incorporates a custom developed temperature control system
utilizing a PID algorithm that can maintain the water temperature for brewing your
espresso within one degree of the selected value. Users can easily change the water
temperature to suit their own taste. The actual temperature of the boiler is displayed by
a bright red LED display with a green light signifying when the water is ready for brewing
your espresso.
Home espresso machines usually require a rapid heat up speed. This requirement
makes it difficult to obtain precision and stable temperature control, especially for a
stainless steel boiler/group head. Precisia has achieved superior performance with
these usually-contradictory parameters through innovative hardware and software
design. The system generally takes about 5 minutes to heat up from room temperature
and less than 2 minutes between each shot.
Precision Shot Volume Control
The shot volume of the espresso can be easily adjusted to suit the user’s preferences.
The shot volume is adjusted by varying the pumping time with one-second accuracy.
