This is the newest version for 2014 which is now the 920XL. The updates over the BES900 are the ability to descale at home, the ability to control steam temperature to increase or decrease steam pressure and an improved 2 year warranty.
Espresso perfection, requires precision temperature and pressure control, consistently, every time. At the heart of this machine is its Dual Stainless Steel Boiler heating system. The brew boiler, for the espresso shot, extracts to within 1'C and a separate steam boiler, which offers instant and powerful steam on demand. So you can extract your shot, at the right temperature, delivering optimal flavour and steam your milk to cafe quality, at the same time. What's more, there is another element in the group head, ensuring the entire system offers a consistent temperature.
The Breville Dual Boiler also features an Over Pressure Valve, which comes standard on almost all commercial cafe machines. This commercial feature limits the maximum pressure throughout the extraction to 9 bar, preventing bitter flavors in the shot. It also offers a true low pressure pre-infusion, which gradually increases the pressure to gently expand the grinds for an even extraction.
The temperature of your brew water is very important. On the Breville, that temperature is programmable, as is the volumetric dose, which will help keep you within your brewing parameters. Heats up in about 8 minutes. Easy to use front fill water tank, shot timing clock, and pressure gauge.
Good, reliable espresso is all about solving as many variables as possible. The Breville Double Boiler goes a long way to helping you do just that.
