In beverage production, especially when it comes to creating non-alcoholic or low-alcohol products, traditional methods of alcohol removal can sometimes compromise the integrity of the beverage’s original flavor and aroma. That’s where vacuum distillation comes in—a highly efficient and gentle process designed to preserve the essence of a drink while reducing or eliminating its alcohol content. At BevZero, we specialize in this cutting-edge dealcoholization method to ensure that your beverages maintain their full flavor profile while meeting your desired alcohol content.

What is Vacuum Distillation?

Vacuum distillation is a separation process that utilizes lower temperatures under reduced pressure (vacuum) to distill and extract components of a liquid, such as alcohol and volatile aromas, without subjecting the product to high heat. The reduced pressure lowers the boiling points of these compounds, allowing for their separation at significantly lower temperatures compared to traditional distillation methods. This lower-temperature process is particularly useful in the non-alcoholic wine industry, where preserving the integrity of delicate flavors while reducing the alcohol content in wine is paramount.

How Vacuum Distillation Works

At its core, vacuum distillation operates by reducing the atmospheric pressure inside a distillation chamber. This reduction in pressure causes the boiling point of liquids, including alcohol and other volatile compounds, to drop. Instead of using high heat to evaporate the alcohol, vacuum distillation enables the process to occur at much lower temperatures, which is crucial in maintaining the flavor and aroma compounds of beverages.

The process works in three key steps:

Volatile Aroma Capture

As the temperature in the vacuum chamber rises slightly, the most volatile compounds—aromas—are the first to evaporate. These delicate molecules are quickly captured and condensed for later reintroduction into the beverage, ensuring that the drink’s original aromatic profile is not lost during alcohol removal.

Alcohol Separation

Once the aromas have been extracted, the temperature is raised just enough to evaporate the alcohol. Because of the vacuum, this evaporation occurs at a lower temperature than the alcohol’s normal boiling point, which helps to maintain the integrity of the beverage’s flavors and structure.

Reintroduction of Aromas

After the alcohol has been removed, the volatile aroma compounds are reintroduced to the dealcoholized beverage. For wine makers looking to jump into NA, this ensures that the end product maintains its original sensory characteristics while being alcohol-free or low in alcohol.

Key Advantages of Vacuum Distillation

Vacuum distillation offers several advantages over traditional distillation techniques, especially when it comes to producing high-quality, low- or no-alcohol beverages.

Lower Temperature, Greater Retention of Flavors

Alcohol typically boils at 78.37°C (173.1°F) under normal atmospheric pressure. In vacuum distillation, the boiling point of alcohol drops significantly, often to as low as 30-35°C (86-95°F), depending on the degree of vacuum applied. This means the beverage is exposed to much less heat, which helps preserve delicate flavor compounds and aromas.

Short Residence Times

One of the unique benefits of vacuum distillation is the short residence time that liquids spend in the distillation chamber. Because the separation process happens more quickly and at a lower temperature, beverages are exposed to the heat for a much shorter period of time. This further minimizes the risk of thermal degradation of flavors and aromas.

Single-Pass Distillation

Another major advantage of vacuum distillation is that it can often be done in a single pass making it easier to embrace the rise of nonalcoholic wine. Traditional distillation processes may require multiple stages to fully separate the alcohol from the beverage, but with vacuum distillation, the process can often be completed in just one cycle. This not only speeds up production but also reduces the amount of handling and potential exposure to heat, ensuring a more natural and unaltered end product.
