Fermentation
Fermentation is a key natural process used in making alcoholic beverages like beer, wine, and spirits. It's the stage where sugars are converted into alcohol by using yeast. Think of it like baking bread - yeast transforms ingredients into something new, but in this case, it creates alcohol instead of making dough rise. Understanding fermentation is crucial for anyone working in beverage production because it determines the alcohol content, flavors, and overall quality of the final product. This process is similar across different types of alcohol production but varies in specific techniques and ingredients used.
