What is a spinning cone column and which premium NA brands use it?
The SCC was developed by CSIRO (Commonwealth Scientific and Industrial Research Organisation) in Australia in the late 1980s and commercialised by Flavourtech, which remains the primary manufacturer. The rotating cones inside the column spin at 350–500 RPM, spreading the liquid feed into a very thin film (0.1mm) over the cone surface, dramatically increasing the surface area for evaporation. Combined with vacuum (reducing pressure to 50–200 mbar) and counter-current steam, this allows volatile aromatic compounds to evaporate at temperatures that would be impossible in conventional atmospheric distillation.
The two-pass design is the critical innovation. In Pass 1, steam at a low rate strips only the volatile aromatics while leaving most of the alcohol in the liquid — these volatile compounds (terpenes, esters, sulphur compounds) are condensed and stored separately. In Pass 2, a higher steam rate removes the alcohol. The dealcoholized base is then recombined with the captured aromatics. Because the aromatics were never subjected to the alcohol-stripping conditions of Pass 2, they retain their fresh character. This is why SCC-processed wines often smell dramatically more like their alcoholic originals than vacuum-distilled equivalents.
Premium brands known to use SCC or equivalent low-temperature technology include Leitz Eins Zwei Zero (Germany), Thomson & Scott Noughty (UK), Edenvale (Australia), and several Californian and South African NA wine producers. The system is expensive — full production lines cost €300,000–€1.5M — which is why smaller producers typically contract to specialist dealcoholization facilities rather than owning their own systems.
| SCC Pass | What's extracted | Why |
|---|---|---|
| Pass 1 (low steam rate) | Volatile aromatics (esters, terpenes, sulphur compounds) | Captures fragile aromatics before alcohol removal damages them |
| Pass 2 (high steam rate) | Ethanol and remaining volatiles | Removes alcohol from the now-aroma-stripped base |
| Recombination | Pass 1 fraction + dealcoholized base | Restores aroma to a now alcohol-free liquid |
