Espresso perfection requires precision temperature and pressure control, consistently, every time, and the Sage by Heston Blumenthal Dual Boiler™ espresso coffee machine will deliver just that. Dual Stainless Steel Boiler heating system The brew boiler, for the espresso shot, extracts to within +/- 1°C and a separate steam boiler offers instant and powerful steam on demand, so you can extract your shot at the right temperature, delivering optimal flavour. You can also steam your milk at the same time. The 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, 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, for a smoother taste. Programmble There's much more to this machine for the coffee connoisseur. Brew temperature and pre-infusion pressure and duration are all programmable. A quick heat up function, front fill water tank and programmable dose enable easy use. A shot clock and pressure gauge are also on hand to help you improve your barista skills over time. All you'll need are some fresh beans, a grinder and a bit of practice to rival the best coffee shops. White Glove Service We want you to have the best experience with your Dual Boiler, so upon delivery a Sage coffee expert will come to your home and set you on the right path towards extraordinary coffee.
