Distilling is a process that can be used to purify liquids, such as water and alcohol. However, one of the byproducts of distilling is the “head”, which are the volatile compounds that evaporate during the distillation process. Depending on the type of liquid being distilled and the method used, some or all of this head may be thrown away. In this article, we will examine how much head is typically thrown away when distilling different substances and explore why it needs to be disposed of in this manner.The amount of head generated during distillation depends on the type of material being distilled, the distillation method used, and other factors such as the temperature and pressure. Generally, distillates have a higher vapor pressure than the feed material, so some of the feed material will evaporate into vapor during distillation. This vapor can eventually condense at the top of the column and form a “head.” The amount of head generated is typically measured in terms of volume or mass.
Head
When distilling, the term ‘head’ refers to the initial portion of a distillation run. This is the part of the process where the still is first filled with liquid and then heated to begin separating out different components. The head is usually rich in volatile compounds and can be identified by its strong smell. The head is usually collected separately from the rest of the distillate as it can be more harsh in flavor and contains higher levels of methanol and other undesirable compounds.
The head should be discarded or used for other non-drinking purposes, such as producing cleaning agents or fuel alcohol. After the head has been removed, the heart of the distillate can be collected which is generally considered to be of better quality than the head. Once all of the desired components have been separated out, then they are blended together to create a finished product.
The Benefits of Throwing Away Heads When Distilling
Distilling alcohol at home can be a rewarding experience, and part of the process involves throwing away the heads. This may seem counterintuitive, as many people are used to consuming the entire product from distillation. However, throwing away the heads can actually be beneficial for several reasons.
The first reason is to help ensure that your final product is free of any harmful substances. The heads are the first portion that comes out of your still, and they contain a higher concentration of any impurities or toxins that may have been present in your original mash. By discarding them, you can help make sure your finished product is safe to consume.
Another benefit of throwing away heads is that it helps improve the taste and quality of your final product. The heads contain a lot of off-flavors and compounds which can negatively affect the flavor and aroma of your alcohol if it’s included with the rest of your distillate. By discarding them, you can help ensure your final product has a smoother taste and better aroma.
Finally, throwing away heads when distilling can also help save time and energy
Identifying the Head During Distillation
Distillation is a process used to separate different compounds from a liquid mixture. During distillation, the mixture is heated and vaporized, then cooled and condensed back into a liquid. The components of the mixture vaporize at different temperatures, allowing them to be separated into fractions known as the head, heart, and tail. Identifying the head during distillation is important for ensuring that only the desired components are collected.
The head of a distillate contains the most volatile compounds that have the lowest boiling points. This fraction may also contain some undesirable compounds that can have unpleasant odors or flavors. It is important to identify and remove the head before collecting any other fractions from a distillate.
The best way to identify and separate the head from a distillate is by using an analytical technique known as gas chromatography (GC). GC involves passing a sample of the distillate through an instrument that separates different compounds based on their boiling points. By analyzing a sample of the distillate with GC, it is possible to accurately identify and separate out its components including those in
Different Types of Heads During Distillation
Distillation is a process used to separate liquids from a mixture. As the liquid mix is heated, the components with lower boiling points vaporize first, with those of higher boiling points left behind. The vaporized liquid is then condensed and collected. In the distillation process, there are three types of heads that can be collected – light heads, middle heads, and heavy heads.
Light heads are the first fraction of liquid that comes off during distillation. This fraction has the most volatile components and can contain a large amount of impurities. It is typically discarded due to its high concentration of impurities and low concentration of desired compounds.
Middle heads are the second fraction that comes off during distillation. This fraction contains some impurities but has a higher concentration of desired compounds than light heads. It is typically used in products such as perfumes or colognes due to its high concentration of desired compounds.
Heavy heads are the last fraction that comes off during distillation and are typically collected for further processing or use in products such
What Happens If Head Is Not Thrown Away When Distilling
Distillation is a process used in the production of spirits, such as whiskey and vodka. In this process, different components of the spirit are separated based on their boiling points. In traditional distillation, the “head” is the first portion of the liquid to come off in the distillation process. This head contains high concentrations of volatile compounds such as methanol and acetone, which can be harmful if consumed in large quantities. As a result, most distillers will discard the head and only keep the “heart” and “tail” for further processing and eventual bottling.
If the head is not thrown away during distillation, then these volatile compounds can remain in the spirit, resulting in an undesirable flavor and potential health risks if consumed. The heart and tail are also affected by this process as they may contain trace amounts of these compounds as well. For this reason, it is important to discard the head when distilling to ensure that only desirable components are present in the final product.
Why Is It Important to Throw Away Head When Distilling?
Distillation is a process commonly used to purify liquids. During the process, vapors are collected and condensed into a liquid form. It is important to throw away the head when distilling in order to ensure that impurities are not present in the distillate. The head, or foreshots, refers to the first few drops of liquid that evaporate during the distillation process. These drops contain high levels of methanol and other impurities, which may be harmful if ingested. Throwing away the head eliminates these impurities from the final product, ensuring that it is safe for consumption.
Additionally, throwing away the head helps ensure that the flavor and aroma of the distilled liquid remain consistent. The foreshots tend to contain compounds that can alter both the flavor and aroma of a distilled product if not discarded properly. This can result in a final product that tastes different than expected or has an unpleasant smell. By discarding the head, you can ensure that these compounds are not present in your final product and maintain its desired flavor and aroma profile.
Throwing Away Head During Distillation
Distillation is a process of separating a liquid mixture into its components based on their boiling points. During distillation, the most volatile component will evaporate first and condense at the top of the apparatus. This component is known as ‘head’. Throwing away the head during distillation is essential to obtain pure components from the liquid mixture. There are several techniques which can be used for throwing away head during distillation.
The most commonly used technique for throwing away head is to install a water-cooled condenser in the distilling apparatus. The condenser works by cooling the vapors from the mixture before they reach the receiving flask. This helps in getting rid of any residual liquid which may be present in the vapors and ensures that only pure components are collected in the receiving flask. Another method for throwing away head during distillation is to use a Dean-Stark trap or receiver in between the condenser and receiving flask. The Dean-Stark trap collects any residual liquids that may still be present in the vapors before it reaches the flask, thus helping to achieve pure components.

Conclusion
The amount of head you throw away when distilling depends on the type of still you are using and the quality of spirit that you wish to produce. Most beginner stills will throw away a significant amount of head, but as you gain more experience and knowledge, you can reduce the amount of head thrown away. Additionally, you can also use techniques such as stripping runs or re-distilling to further reduce the amount of head thrown away. While it is important to pay attention to how much head is being discarded, it is also important to remember that some heads contain valuable flavor compounds that can be used to improve your spirit.
Overall, distillers should be aware of how much head they are throwing away when distilling in order to maximize their yields and produce the best possible quality spirit. Monitoring head losses can help ensure that only the appropriate amount is discarded and that valuable flavor compounds are not being wasted.
