Spinning Cone vs. Vacuum Distillation for Non-Alcoholic Wine

Vacuum distillation and the spinning cone column both remove alcohol from finished wine at low temperature to make non-alcoholic wine without cooking the aroma. Vacuum distillation lowers air pressure so alcohol boils off at around 30°C. The spinning cone spins wine into thin films across rotating cones, stripping alcohol in stages with a countercurrent of steam. PARAGRAPH uses vacuum distillation.

People assume there is one industrial process behind every non-alcoholic wine on the shelf. There are two main ones, built on different mechanics, and they leave a wine tasting noticeably different depending on which one you use and how carefully you run it.

Both methods exist to dodge the same 78°C problem

Standard distillation removes alcohol by boiling it off at around 78°C at sea level, and that temperature destroys most of the delicate aroma compounds that make a wine smell and taste distinct. Cherry, herb, and floral notes in a Tempranillo do not survive that kind of heat. So both methods find a way to pull the alcohol out at a much lower temperature.

How vacuum distillation works

Vacuum distillation lowers the air pressure inside a sealed chamber holding the wine. Under reduced pressure, alcohol boils off at a far lower temperature than it would at normal atmospheric pressure, around 30°C, well under the 78°C that standard distillation requires. The wine barely gets warm.

This is the method we use for PARAGRAPH. Our still runs at about 30°C, and we take the base wine to it at 2 to 4 years of age for the Tempranillo and 12 months for the Chardonnay. Running that cool means the volatile aroma compounds in our Tempranillo, the ones responsible for its fruit and structure, stay largely intact. The wine that comes out still smells and tastes recognizably like the wine that went in, minus most of the alcohol. The step-by-step version is in how non-alcoholic wine is made.

How the spinning cone column works

The spinning cone column takes a different mechanical route to the same low-temperature goal. Wine is fed into a vertical column packed with alternating rotating and stationary cones, also operating under vacuum. As the wine spins across the cone surfaces, it forms a thin film, which multiplies the surface area exposed to a countercurrent of steam or nitrogen moving through the column.

That large surface area lets the process strip out alcohol and volatile aroma compounds efficiently, often in two passes: one pass captures the delicate aromatics before they are lost, and a second pass removes the bulk of the remaining alcohol. Some producers add the captured aroma fraction back into the dealcoholized wine afterward.

What each method does to aroma and structure

Both methods protect volatile aroma better than traditional heat distillation, and they do not produce identical results. Vacuum distillation, run carefully, tends to hold a wine's aroma profile close to its original state because the wine spends less time being handled. The spinning cone's two-stage separate-and-reintroduce approach can recover aroma well, and the result depends on how well the aroma fraction goes back in. In our own process, 100% of the wine's captured aroma is returned: the aroma is concentrated in a small amount of the wine's own alcohol and added back, and the finished wine stays under 0.5% ABV.

Neither method restores the body and mouthfeel that alcohol itself contributes. Alcohol has weight and texture in wine, and removing it by either method leaves a lighter-bodied wine than the original. That is a separate problem from aroma. We handle it through base wine selection and blending, and I cover both in how we keep tannin and structure without the alcohol.

Why PARAGRAPH chose vacuum distillation

We use vacuum distillation. For a Tempranillo grown at altitude, with the structure and fruit character we are working to preserve, running the process at the lowest practical temperature matters more to us than the two-stage aroma capture the spinning cone offers. I put it this way to our team: "The still gives us one dial, temperature, and we can hold it exactly where the wine needs it. Fewer stages mean less chance of oxidation, and more freshness and character in the final wine."

Producers using the spinning cone column make excellent non-alcoholic wines too. The choice comes down to the grape, the team's experience with the equipment, and the character they want to protect.

Both processes exist because the category now justifies the investment. US non-alcoholic wine sales grew 29.1% in 2025 while total US wine sales fell 4.9% (NIQ, 2025 year in review). Wines finishing under 0.5% ABV through either method qualify for "non-alcoholic" labeling under FDA guidance (CPG Sec. 510.400), provided the label also states the wine was dealcoholized or alcohol-removed, which is the term we use on ours.

What the method tells you when you are choosing a bottle

The method behind a bottle is rarely printed on the label, and it shapes what is in the glass. A wine that tastes flat, cooked, or one-dimensional may have gone through a harsher process, or a low-temperature process run without much care. A wine that still carries fruit character and some structure was likely made with more attention at the dealcoholization stage, whichever method the producer used.

If you want to taste what a carefully run vacuum distillation preserves in a Tempranillo, that is what PARAGRAPH Tempranillo is built to show.
