Why the M5

Faster pours

Pours up to 2.5 oz per second with a bottle-quality pour, so lines move faster at the rail.

Brix set at the factory

Calibrated orifices set brix before it ships, including for thicker syrups. Less setup on site.

Constant Flow Valves

Newton CFVs sit after the manifold, holding each line at its own steady pressure for a consistent pour.

Lighter, low-profile handle

A redesigned matte handle that's lighter in the hand over a long shift.

Simpler service

Fewer parts, a toggle shut-off and a lever-action tube collector make maintenance quicker.

Works with your system

Fully hydraulic with no power required, and compatible with any bag-in-box system.

M5 vs. M4: what's different

The Mark IV (M4) has been the industry standard for decades. The M5 keeps the Wunder-Bar fundamentals and changes how flow and brix are controlled.
