The Revolution

Trusted to its history, the sector of coffee machine production is seriously evolving. Not only it has evolved in the beautiful
design aspects, but also its technology. Nowadays, a wide rage of technologies makes the machine more flexible, enabling baristas to
pursue the paths in preparing espressos in their own way.
Here are some of the interesting technologies covered:

Brew Ratio Espresso Pre-set Preinfusion Time
The concept is to be able to control or preset the ratios of coffee in and out. This Pre-infusion is a process built into
is where the espresso machines install scales on the drip tray. Some offers to weigh the espresso machines where hot water is
coffee in the portafilter and weigh the yield of the liquid coffee out on the tray. For applied to the ground coffee for an initial
example, a 20 grams dosed portafilter with a built-in scale and presetting the brew ratio period of time but at a pressure that is
at 1:2, this would result in espresso brewing only up to 40 grams of coffee liquid in the much lower than the ultimate extraction
drip scale. It’s up to the barista to pick the ratio. This technology is installed on many pressure. Most machines today, enable
commercial grade espresso machines like: La Marzocco’s Linear PB with its “Auto Brew baristas to set up their own pre-infusion
Ratio”, Victoria Arduino VA388 Black Eagle “Gravitech”. or the blooming time, so that it suits that
particular coffee.

Pressure Profi ling
Increasing the brewing pressure instantly to get more of the extraction and at
different brewing period enable barista to have more fun with their espresso production.
For example, 10 bar of pressure at the beginning first 10 seconds of the brew for more
extraction in the beginning and 2 bars at the very end of the extraction to get less of the
non-favorable flavor. Available in the famous Slayer, Bezzera, VBM and UNIC. Different temperature for each
group head
Because different coffees are to be
brewed at different temperature to suit
each preferences. Many of the espresso
machines like the Victoria Arduino Black
Eagle enables barista to brew at different
temperatures and pre-set the temperature
Bezzera Arcadia VBM Tecnique for each group head. Moreover, some
machines like the new VBM allows baris-
tas to change the temperature instantly
Memory and Pre-set when they are brewing their espressos.
Most espresso machines allow the memory or a pre-set brewing ratios. This is THERMALINK NETWORK® technol-
somewhat similar to the weigh measuring but instead it duplicates the shot that you ogy from UNIC offers the possibility to
have pulled. This enables all the shots to brew at the same amount of liquid if pressed independently set each group. Some even
the preset button. They key is to make sure that everyone in the cafe can deliver the go further to controlling temperature of
same perfect shot every time. This technology is called “recipe shots” and is available the cup heating trays and the hot water
