Ristretto Dual Boiler
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
Home espresso fails at consistency, not romance. The Ristretto fixes the boring part — temperature held to the tenth, pressure you can shape, a shot log that keeps you honest — and lets the romance take care of itself.
Thermal mass is the quiet ingredient. Oversized boilers, insulated lines and saturated or thermosyphon groups hold the brew path within a fraction of a degree, so the tenth shot of the morning tastes like the first. PID control reads twice a second; the needle on the gauge is there for the pleasure of it.

Questions, Answered
Tank or plumbed?
Machines listed as plumbable ship with both options where the platform allows; our installation includes connection to treated water and a drain if they are within reach of the bench.
Is training included?
Every machine handover includes a commissioning session; espresso machines add a barista induction on your own equipment — dialling in, milk, cleaning and the daily routine.
