Homebrewing is the process of brewing beverages such as beer, wine, mead, and cider at home. One of the critical aspects of homebrewing is controlling the alcohol content, which is measured as Alcohol By Volume (ABV). The alcohol content in homebrews can be increased by adding more fermentable sugar for yeast to feed on. However, simply adding extra sugar without considering the yeast's capacity can lead to stressed yeast, resulting in off-flavors and undesirable characteristics in the final product. Therefore, it is crucial to select the appropriate yeast strain and maintain a balanced recipe to achieve the desired ABV level without compromising flavor and aroma. Additionally, factors such as fermentation temperature and the use of adjunct sugars or honey can influence the alcohol content and the overall quality of the beverage.

What You'll Learn
Alcohol content can be measured using a hydrometer
To use a hydrometer to measure the alcohol content of a homebrew, you would take a sample of the wort at the end of your boil, after it has been cooled and before pitching the yeast. This sample is placed in a test tube, and the hydrometer is gently placed inside, taking care to avoid creating bubbles. The hydrometer should float freely without touching the sides of the container. Once the hydrometer has stabilised, a reading is taken from the surface of the liquid, known as the original gravity reading. This sample can then be returned to the fermenter, as long as the equipment is properly sanitised to avoid contamination.
At the end of fermentation, before bottling the beer, a final gravity reading is taken in the same way. The difference between the original gravity and final gravity readings is then used to calculate the ABV (alcohol by volume) of the beverage. This can be done using an online ABV calculator or a formula provided with the hydrometer.
It is important to note that the temperature of the liquid may affect the accuracy of the hydrometer reading. Therefore, if the liquid is a different temperature than the hydrometer's calibration temperature (usually 15°C or 20°C), the reading may need to be adjusted accordingly. Additionally, some beverages, such as kombucha or water kefir, may not provide accurate readings due to the presence of suspended particles.

Yeast turns sugar into alcohol and CO2
The role of yeast in the fermentation process is to turn sugar into alcohol and carbon dioxide (CO2). This process is the same whether you are brewing beer or making wine, or baking bread. However, the length of time it takes for yeast to produce alcohol varies depending on the type of yeast and the environmental conditions, such as temperature and nutrients.
In brewing, yeast consumes sugars and converts them into CO2 gas and alcohol. Typically, about half of the sugar turns into CO2, and the other half turns into alcohol. The more sugar that is available, the more alcohol will be produced. However, different strains of yeast have varying levels of alcohol tolerance, and once the yeast reaches a certain level of alcohol, it will struggle to ferment any further. Therefore, it is important to choose the right type of yeast and ensure it has the right conditions to ferment.
To increase the alcohol content of your homebrew, you can add more fermentable sugar for the yeast to feed on. However, simply adding extra cups of sugar to your wort is not enough to achieve a higher ABV (alcohol by volume). The yeast you use must be able to handle an increase in sugar. Some strains of yeast do not have the capacity to produce more alcohol, and even if a strain can handle a higher percentage, a low cell count can cause the yeast to become stressed, resulting in off-flavours and other undesirable characteristics in your brew.
When making wine, you can add sugar during the secondary fermentation stage to help prevent the yeast from becoming stressed. However, it is not always necessary to add additional sugar, as most recipes call for all the sugar to be added during the primary fermentation stage. If you are making beer, you will also need to chemically decompose the starches in the grain into simple sugars, as yeast cannot eat starches.
During the fermentation process, it is important to keep the fermentation vats sealed from the air. Yeast produces alcohol in the absence of oxygen. If oxygen is present in the vat, the yeast will only produce carbon dioxide without alcohol. Therefore, the oxygen in the vat must be consumed by the yeast before they start making alcohol.

Secondary fermentation is important to remove sediment
Sediment can negatively impact the taste and clarity of your homebrew, so it's important to remove it through secondary fermentation. This process, also known as re-racking, involves transferring your brew from the primary fermentation vessel to a secondary vessel.
During primary fermentation, sediment or "lees" accumulates at the bottom of the vessel. This sediment can be detrimental if left in contact with your brew for too long. Therefore, once primary fermentation is complete, you carefully transfer your brew to a sanitized secondary vessel, being careful to avoid transferring any of the lees.
The timing of this transfer is crucial. For wine, it's recommended to transfer it to a secondary fermenter when fermentation begins to slow down, usually within 5-7 days. This first racking removes the majority of the sediment, but additional rackings may be necessary as more sediment forms. With each progressive racking, your brew will become clearer. For mead, you can confirm that primary fermentation is complete by using a hydrometer to measure the specific gravity, which should remain stable for several consecutive days or when bubbling has stopped or minimized.
After transferring your brew to the secondary vessel, you can choose to add additional flavorings or ingredients to enhance the taste and color. This could include fruit, spices, or oak chips. Allow your brew to sit for a few weeks to let the flavors develop and for further clarity.
Some brews, like mead, can benefit from extended aging, so it's a good idea to taste test periodically to determine the optimal time for bottling. By performing secondary fermentation and properly managing sediment, you can ensure a clearer, better-tasting final product.

Corn sugar is a popular choice for homebrewers
Homebrewing is an art, and brewers are always looking for ways to improve their craft. One of the key considerations is the type of sugar used, as it can significantly impact the flavour, aroma, texture, and alcohol content of the finished product. Corn sugar, also known as dextrose, is a popular choice among homebrewers for several reasons.
Firstly, corn sugar is highly fermentable, meaning it will be efficiently converted into alcohol by the yeast, resulting in a higher alcohol content in the final product. This is particularly desirable for brewers aiming for a higher ABV (Alcohol By Volume). Additionally, corn sugar is a simple sugar, which means it dissolves quickly and easily in water, ensuring even distribution throughout the wort. This even distribution helps prevent inconsistencies in the fermentation process and contributes to a consistent flavour profile in the finished beer.
Another advantage of corn sugar is its affordability. Corn is a widely available crop that is easier to process into sugar than sugar cane, making it a more cost-effective option. This is especially significant for large-scale commercial brewers, but it can also benefit homebrewers looking to brew on a budget. Corn sugar is also flavourless, so it won't alter the flavour profile of the beer like other sugars, such as cane sugar, which can impart a subtle molasses-like taste.
Finally, corn sugar is easy to use. Its high fermentability and solubility make it a reliable choice for homebrewers, reducing the risk of errors or inconsistencies in the brewing process. This ease of use is particularly appealing to beginner homebrewers who are still refining their techniques. Corn sugar is also commonly used in specific beer styles, such as American Light Lagers, where it helps to lighten the body of the beer and contribute a mild sweetness.
In conclusion, corn sugar is a versatile and effective ingredient for homebrewers, offering convenience, consistency, and the ability to achieve higher alcohol levels without impacting the flavour profile of the beer.

Alcohol content can be increased by adding honey
Honey can be added to the boil to increase the final alcohol content, add a light honey flavor, or lighten the body of a beer if used as a replacement for malt extract. If you want a lot of honey character, add diluted, heat-treated honey to the primary fermenter. Adding honey to the beginning of a long, furious boil will kill any wild yeast, deactivate enzymes, and remove beeswax. Honey ferments out so completely that (95% of carbohydrates) very little honey character will be left in the beer unless you take special precautions.
If you want to increase the alcohol content without adding honey, you can add more fermentable sugar for the yeast to feed on. However, not all yeast can handle an increase in sugar, and some strains do not have the power to produce more alcohol. Therefore, it is important to experiment and adjust the number of other ingredients to maintain a balance of flavor and aroma.
Additionally, it is worth noting that increasing alcohol content will alter the intended flavor, aroma, and texture of the finished beer.
