The Difference Between Distilling and Fermenting Alcohol Explained

Alcohol is made by fermentation and can be further concentrated by distillation. They are two different processes that can be carried out sequentially.

The quality and taste of the distilled product depends largely on the purity of the fermented alcohol.

What Is Distillation?

Distillation is the process of separating a liquid mixture into several individual components by virtually eliminating the undesired components.

Distillation can be done with any fermented substrate and will yield a stronger liquor in return.

This process is employed in industries ranging from fuel and pharmaceuticals to spirits, due to its ability to separate mixtures based on their boiling point; distilling is often used for purification as well as re-concentration when it comes to producing alcoholic drinks.

It is a relatively simple technique that can, with the right equipment, be performed by anyone at home.

Distilling differs from fermented beverages in that, unlike fermentation, distillation does not involve any conversion of sugars into alcohol — instead, the ethanol present in a fermented beverage is further concentrated through evaporation and condensation.

The result can be anything from vodka or whiskey to rum or tequila depending on the product’s ingredients and desired flavor profile.

In summary, distillation involves a more concentrated version of an already alcoholic beverage product; this allows higher alcohol content while retaining flavor complexity.

What Is Fermentation?

Fermentation is the process of converting sugar, starch, and other simple carbohydrates into alcohols and carbon dioxide.

Fermentation requires only a substrate (e.g. malt or juice) and a container with an airlock.

This process provides the alcohol, flavor and aroma associated with most typical beverages like beer, hard cider or wine.

In contrast to fermentation, distillation is a form of separation widely used for purifying liquids using heat (or cooling). By heating a fermented beverage past its boiling point for ethanol (78 degrees Celsius), it can be separated from other non-alcoholic components present in the source solution.

Fermentation requires much more moderate temperatures and can be done by anyone at home with minimal equipment.

Distilled beverages tend to have a much higher concentrations of alcohol than those produced solely through fermentation; they are also typically clearer since they have been filtered of larger particles during this process.

It is the key biochemical process used to make alcoholic beverages such as beer, wine, mead, and commercial distillation spirits.

Fermentation occurs when yeast or sometimes bacteria act on simple sugars present in a solution without oxygen to produce ethanol/alcohol.

The Differences Between Distillation and Fermentation

Distillation and fermentation are two common processes for producing alcoholic beverages.

Although the end results of both processes involve alcoholic beverages, the methods in which they are produced differ drastically; distillation involves heating a liquid to vaporize its components, while fermentation occurs when yeast converts sugar into alcohol.

Distillation typically yields higher-proof liquors than fermented products as it concentrates the alcohol content of a liquid through boiling, condensation and collection.

To produce distilled drinks such as whiskey, vodka or rum, grain mash is heated until its volatile compounds become vaporized.

After being administered with other filtration techniques to adjust taste and clarity, the resulting liquid has significantly higher alcohol by volume (ABV) compared to beer or cider that result from fermentation.

Fermentation on the other hand begins with converting sugar molecules into ethanol using yeast enzymes; this process produces lower ABV liquids such as beer, wine or cider in comparison to their distilled counterparts.

Depending on specific factors such water temperature and pH levels that contribute towards flavor composition and fragrant profiles of a given beverage categorized under different beer types – lager beers tend toward a light banana/clove profile for instance – a multitude variations can be produced depending on design goals of concentration versus flavor complexity .

Pros and Cons of Distillation and Fermentation for Producing Alcohol Beverages and spirits.

At the heart of any spirit is the process of distillation and fermentation. Both processes are closely linked, yet they result in two distinct methods of alcohol production. Distillation involves heating and cooling a liquid to create a concentrated version, while fermentation creates alcohol through the conversion of sugar into ethanol with yeast.

Each process has its own unique set of benefits and downsides to consider. The biggest advantage that distilling provides is a higher level proof beverage – alcohol distilled from grain or grapes typically has an ABV starting around 40%. This can be further elevated when additional distillations occur.

On the other hand, this method usually relies on additional steps to create flavoring such as aging in wooden caskets and adding flavorings, whereas fermentation will produce something with more complex flavors already present within in it due to exposure from yeast during formation.

However generally fermenting produces beverages that are weaker in strength compared to distilled versions (ABV usually topping off around 20-25%). Ultimately each method comes down personal preference based on intended use for any given beverage produced from either approach

Examples of Popular Alcoholic Drinks Created with Either Process or a Combination of Both

Distilling and fermenting alcohol are two distinct processes that can produce entirely different outcomes.

In distilling, alcohol is produced using heat to boil off liquids and capture their vapors. This vapor is then condensed and distilled again to purify the ethanol content. Some popular alcoholic drinks made using this method include gin, vodka, whiskey, brandy and tequila.

On the other hand, fermentation is a process used to make beer and wine by converting sugars into alcohol without boiling or adding heat.

During this process an enzyme breaks down the sugar molecules into simpler compounds allowing for yeast to break them down further into ethanol and carbon dioxide gases. Popular alcoholic drinks created with a combination of both processes include champagne, hard cider, mead and sake.

What about freeze distillation?

Freeze distillation is a method of creating alcoholic beverages by using cold temperatures to concentrate the alcohol content in a fermented beverage. This process involves freezing the liquid and then removing the ice, which contains less alcohol and more water, leaving behind a more concentrated alcohol content.

Applejack is made using freeze distillation.

The process of freeze distillation is relatively simple. The fermented beverage is placed in a container and then placed in a freezer. As the temperature drops, ice crystals begin to form. The ice is then removed from the container, leaving behind a more concentrated liquid that contains a higher percentage of alcohol.

One of the main advantages of freeze distillation is that it is a relatively simple and low-cost process compared to traditional distillation. However, there are also several disadvantages to this process. One of the main disadvantages is that it can be difficult to control the concentration of alcohol, which can lead to variations in the final product. Additionally, freeze distillation may not remove all of the impurities that traditional distillation can remove, which can result in a lower quality product.

There are several types of spirits that can be made using freeze distillation. One of the most popular is applejack, which is made from fermented apple cider that has been freeze-distilled. Ice cider is another popular product that is made using this process. In addition to these products, there are also a variety of other spirits that can be made using freeze distillation, including eau de vie, grappa, and other types of fortified wines.

In conclusion, freeze distillation is a simple and low-cost method of creating alcoholic beverages with a higher alcohol content. While there are some advantages to this process, there are also several disadvantages to consider, including the potential for variations in the final product and the inability to remove all impurities.

Nonetheless, it remains a popular method for producing certain types of spirits, including applejack and ice cider.


In conclusion, distillation and fermentation are two unique processes used to create alcoholic beverages. Both have advantages and disadvantages depending on what type of drink is being produced.

The main difference between them is the boiling point: whereas distilling requires the raw material to reach its boiling point in order for it to separate into fractions, fermentation only requires sugars from ingredients such as fruit or grains be allowed to convert into alcohol over time with no heat required.

Whether you prefer a light beer crafted through fermentation or an aged whiskey distilled over many years, understanding both methods can help deepen your appreciation for all types of drinks! Join us today if you want more information about this fascinating topic!
