Dealcoholisation methods Vacuum distillation
Aroma moduleSolos
Not a dealcoholisation method: it pulls aroma back from DeAlcoTec distillate by solid-phase extraction. A module.
- 1 Column DeAlcoTec distils: ethanol and volatiles leave together.
- 2 Resin Solos adsorbs aroma from the distillate (solid phase).
- 3 Essence It is desorbed and put back into the NA wine.
| Driving force | Adsorption on resin (SPE) |
|---|---|
| What leaves | The column already took the alcohol; Solos works the distillate |
| What happens to water | About 15% on the whole train (Solos figure) |
| Heat | The heat is DeAlcoTec’s, not Solos’ |
| Type | Aroma module Part of Vacuum distillation |
|---|---|
| Developer | Prodalim (Solos / FlavoLogic); Centec DeAlcoTec column |
| Volume loss | About 15% (Solos figure for the whole train) |
| Final ABV | Centec <0.01%; Solos claims <0.005% |
| Wines known to use it | Zeronimo (Austria), Oceano Zero (California); plant in Valencia |
| Best for | Cellars that put aromatic completeness first in a no-alcohol wine. |
What it is
Solos is not a way to strip alcohol. It is Prodalim’s aroma-recovery module (through Solos and FlavoLogic GmbH, the German firm that patented the system and that Prodalim later bought), bolted onto Centec’s DeAlcoTec vacuum still. It goes at the biggest quality problem in non-alcoholic wine: aroma loss.
Centec’s column takes the alcohol out. Solos then works on the distillate. It is a modification of the thermal route (vacuum plus essence put-back), not a fourth process.
How it runs
Under vacuum, alcohol leaves the wine and takes volatiles with it: esters, higher alcohols and other molecules that carry varietal character. Solos then runs solid-phase extraction (SPE) on that distillate: aroma adsorbs onto a regenerable resin bed and is later desorbed as a concentrate, the essence, which goes back into the dealcoholised wine. SPE does not mean “single-phase extraction”.
Against older capture kit such as spinning cone or GoLo, the point is not another evaporation geometry. It is not to flatten the aromatic profile once the alcohol has already left.
In October 2025 Solos announced its first own plant at Alcàsser, Valencia, opened in January 2026: DeAlcoTec, aroma recovery and packing under one roof. A second plant opened in Hopland, California, in February 2026, with Rack & Riddle.
The numbers
Solos’ own 2026 winemaking guideline publishes GC-MS data with and without the module. Those are the maker’s figures, not an independent lab’s. The gap is widest exactly where no-alcohol wine usually fails: esters, the compounds behind fruity and floral character, come back at 7–9% without Solos and at 79–81% with it. Alcohols move from roughly a third to about three quarters recovered; sulfur compounds and norisoprenoids jump much the same way.
Volume loss in the combined process runs around 15%. Centec’s DeAlcoTec column can take a wine below 0.01% ABV; Solos, on that train, claims below 0.005% ABV, among the lowest figures a commercial supplier publishes, which is what strict “alcohol-free” and “0.0%” label claims need in most markets.
Wines that use it
Zeronimo, from Austrian family winery Heribert Bayer, is built on old-vine Grüner Veltliner and Zweigelt, and was named Best Non-Alcoholic Wine in the USA TODAY 10Best Readers’ Choice Awards 2026.
Oceano Zero, the alcohol-removed line from California’s Oceano Wines, was among the first US brands on Solos’ aroma recovery system when the Hopland facility opened in 2026, with a single-vineyard Chardonnay and Pinot Noir.
Solos also runs production and partnerships across Germany, Switzerland, Austria, Spain and France.
