Description

Espresso perfection requires precision temperature and pressure control. At the heart of this machine is its dual stainless steel boiler heating system with electronic proportional-integral-derivative (PID) temperature control. The dedicated espresso boiler temperature is adjustable for different bean roasts and origins, while a separate steam boiler offers instant and powerful steam on demand. This allows optimal coffee extraction and milk texturing simultaneously to cafe quality. The culmination of this is the first domestic espresso machine to pass commercial café standards. This product combines best in class design and attention to detail with ease of use, performance precision and quality.

Key Features
and/or Benefits

Commercial features and performance in a domestic foot print

Traditionally it's been difficult for the budding barista to achieve café quality at home due to the limitations of domestic machine technology and size.

Through innovative design and technology the Breville Dual Boiler™ has successfully condensed commercial features and performance that deliver precision temperature and pressure into a domestic friendly sized platform never seen in this market segment before.

"It is clear this is a La Marzocco GS/3 hunt and destroy machine, scheduled to be priced less than $1500 Australian dollars."
Coffeegeek.com: Mark Prince (commenting on the impending launch of the Dual Boiler and comparing with the $7000+ La Marzocco)

Precision control

Unlocking the complex flavours contained within the coffee bean requires precise constant water temperature (93°C) during brewing. Commercial machines typically achieve this through substantial thermal mass provided by large boilers and saturated group heads.

The Breville Dual Boiler™ achieves commercial precision water temperature (+/- 1°C) through a compact efficient Triple Heating System with electronic proportional-integral-derivative (PID) temperature control.

"I ran 15 tests to see what the actual brewing temperature is and it was consistently 93 degrees plus or minus 1/2 a degree, impressive!"

Precision control... again and again and again

How do you offer a latte or cappuccino after a dinner party without the fear of being stuck in the kitchen for half an hour making them?

The Breville Dual Boiler™ features a dedicated Coffee Boiler and Steam Boiler so that you can simultaneously extract coffee and texture milk at the same time. The dedicated boilers will deliver consistent high quality espresso shots and volumes of silky milk over and over again with no recovery time required. You will back to the dinner table in no time.

Experiment and play

Different bean origins and roast styles can often require subtle changes in the extraction process to get bring out their signature flavours.

The Breville Dual Boiler™ allows the user to tweak the programmable brew temperature (1°C increments) and pre-infusion pressure (time and pressure) to get the best out of your bean. The shot clock and pressure gauge provide useful feedback in guiding you to the perfect extraction. Adjustable pressure pre-infusion has previously only been available in specialized commercial machines and has been achieved through patent pending technology.

Everyday ease of use

Great tasting espresso can only be achieved if your equipment is well maintained, clean and supplied with fresh water. In particular coffee oils deposits in the group head can become rancid overtime and affect the taste and quality of espresso.

The Breville Dual Boiler™ regularly reminds you to clean the group head using the inbuilt clean cycle program. Other enhancements to assist include the integrated water tank calcium filter and hidden tray storing cleaning and maintenance tools. The front fill lid makes topping up the water tank quick, and the drop down 3rd wheel makes maneuvering on the bench easy.
