What are essential oils?
Essential oils are highly concentrated plant extracts that capture the essence of a plant’s fragrance and flavor. They are commonly used in aromatherapy, skincare, and cooking due to their therapeutic properties and intense aroma. Essential oils are derived from various parts of plants, including flowers, leaves, stems, roots, and fruits, through a process called distillation.
How are essential oils extracted?
Essential oils are extracted through a process called distillation, which involves heating the plant material to release its aromatic compounds. There are several methods of distillation, including steam distillation, cold pressing, and solvent extraction. Steam distillation is the most common method used to extract essential oils from plant material. In this process, steam is passed through the plant material, causing the essential oils to evaporate and then condense into a liquid form.
What are the benefits of using essential oils in brewing?

Additionally, essential oils have antimicrobial properties that can help preserve beer and prevent contamination during the brewing process.
How can essential oils be used in brewing?
Essential oils can be added to beer at various stages of the brewing process, depending on the desired flavor profile. They can be added during the boil to extract their volatile compounds, during fermentation to enhance aroma and flavor, or during packaging to add a finishing touch. Essential oils should be used sparingly in brewing, as their concentrated nature can easily overpower other flavors in the beer.
