The majority of compounds in beer come from the metabolic activities of plants and yeast and so are covered by the fields of biochemistry and organic chemistry. [1] The main exception is that beer contains over 90% water and the mineral ions in the water (hardness) can have a significant effect upon the taste. [2]
Zymomonas have not been reported in lager breweries due to the low temperatures (8–12 °C) and stringent carbohydrate requirements (able to ferment only sucrose, glucose, and fructose). It is commonly found in cask-conditioned ales where priming sugar is used to carbonate the beer. The optimum growth temperature is 25 to 30 °C.
The OE (Original Extract) is often referred to as the "size" of the beer and is, in Europe, often printed on the label as Stammwürze or sometimes just as a percent. In the Czech Republic, for example, common descriptions are "10 degree beers", "12 degree beers" which refers to the gravity in Plato of the wort before the fermentation.
While glucose levels that are too low are also a concern (it's called hypoglycemia and particularly presents in people with type 1 diabetes), high glucose can be particularly tricky to lower.
The formation of the cellulose pellicle at the surface of the broth yields a product with unique characteristics that both bacteria and consumers find advantageous. Upon inoculation into the culture, bacteria such as Acetobacter immediately begin pulling glucose molecules together outside of the cell and joining them via β(1-4) linkages to form long, slender structures extending from their ...
At time of harvest, there is usually an equal amount of glucose and fructose molecules in the grape; however, as the grape overripens the level of fructose will become higher. In wine, fructose can taste nearly twice as sweet as glucose and is a key component in the creation of sweet dessert wines. During fermentation, glucose is consumed first ...
