OPTIMAL WATER PRESSURE: The Over Pressure Valve limits the maximum pump pressure throughout extraction helping prevent bitter flavours; Low pressure pre infusion gradually increases water pressure to gently expand grinds for an even extraction. PRECISE ESPRESSO EXTRACTION: Dual stainless steel boilers and heated group head controlled by digital temperature control (PID) brings water to precisely the right temperature (+/- 1? C) to extract maximum flavour potential every time. MANUAL MICROFOAM MILK TEXTURING: The steam wand performance allows you to hand texture microfoam milk of commercial machines that enhances flavour and is essential for creation of latte art. LCD DISPLAY: Allows easy programming and has a espresso shot clock which displays shot duration that guides you to consistent extraction.
