Corvina Tre Alta — 3 Group
Tax included where applicable. Delivery and installation arranged by your concierge.
NAVERQIO Machines — nine bars, held steady
Flagship bars earn flagship thermals. The Corvina Tre runs three coffees at three temperatures, logs its shots, and carries the service network — next-day in Prague and Brno — that a queue out the door assumes.
We build espresso machines the way boiler-makers used to: thick copper and stainless, brass groups machined in-house, silicone-free food-grade seals, and wiring looms labelled so a technician in ten years thanks us by name. Panels come off with a single tool; nothing structural is glued; every fastener is stainless and standard.
Design & Craft
- Cool-touch wands, raised groups for tall cups, barista lights
- Bench-tested in Prague on your water profile before dispatch
- Solid brass groups machined in-house and pressure-tested twice
- Volumetric dosing with barista-override for the shots that matter
- Food-grade, silicone-free seals; every fastener stainless and standard
- Boilers in copper or 316L stainless, insulated and TIG-welded by hand

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.
What water should I use?
Softened, remineralised water around 40–80 ppm hardness. Send us your water report before dispatch and we bench-test the machine on a matching profile — it is part of the NAVERQIO standard.
The NAVERQIO Promise
Every NAVERQIO machine leaves Prague bench-tested on the water profile of its destination — send us your water report and it ships dialled in, with the test shots' numbers in the box.
