What is aerobic fermentation? Aerobic fermentation is a process in which yeast cells convert sugars into carbon dioxide and alcohol in the presence of oxygen. This process is commonly used in the brewing industry to produce beer, as it allows for the production of a wide range of flavors and aromas. Unlike anaerobic fermentation, which … Read more
What is Lactobacillus? Lactobacillus is a genus of Gram-positive, rod-shaped bacteria that are commonly found in various environments, including the human body, plants, and fermented foods. These bacteria are known for their ability to produce lactic acid through the fermentation of sugars, which gives them their characteristic sour taste. Lactobacillus is considered a beneficial bacteria … Read more
What are International Bitterness Units (IBU)? International Bitterness Units (IBU) is a measurement used to quantify the bitterness of beer. It is a scale that indicates the amount of bittering compounds, primarily iso-alpha acids from hops, present in a beer. The higher the IBU value, the more bitter the beer is perceived to be. IBU … Read more
What is Methanol? Methanol, also known as methyl alcohol or wood alcohol, is a type of alcohol that is commonly used in industrial processes, including the production of alcoholic beverages such as beer. It is a colorless, volatile liquid with a slightly sweet odor. Methanol is highly toxic when ingested and can cause serious health … Read more
What is Green Beer? Green beer is a type of beer that is specially brewed and dyed green to celebrate St. Patrick’s Day, a cultural and religious holiday that is celebrated on March 17th.

I. What is Chill Proofing in Brewing? Chill proofing in brewing refers to the process of stabilizing beer by removing haze-causing proteins and polyphenols that can precipitate out of the beer when it is chilled. This process is essential for ensuring that the beer remains clear and stable throughout its shelf life. II. Why is … Read more
I. What is Diacetyl Rest? Diacetyl rest is a term used in brewing to describe a period of time during fermentation where the beer is allowed to rest at a slightly elevated temperature to facilitate the reduction of diacetyl levels. Diacetyl is a natural byproduct of fermentation that can impart a buttery or butterscotch-like flavor … Read more
I. What is Amylose? Amylose is a type of polysaccharide that is commonly found in plants, particularly in grains such as barley, wheat, and corn. It is a linear chain of glucose molecules linked together by alpha-1,4-glycosidic bonds. Amylose is a component of starch, along with amylopectin, and is responsible for the structural integrity of … Read more
What is DMS (Dimethyl Sulfides)? DMS, or dimethyl sulfides, are a group of sulfur compounds that are naturally present in various foods and beverages, including beer. These compounds are formed during the brewing process and can have a significant impact on the flavor and aroma of the final product. DMS is known for its distinctive … Read more
I. What is Autolysis in the Brewing Process? Autolysis is a natural process that occurs in brewing when yeast cells die and break down, releasing enzymes and compounds that can affect the flavor and quality of the beer. This process is also known as yeast autolysis or self-digestion, and it typically happens during the fermentation … Read more
