Beer ClassificationWhat is more refreshing on a hot summer day than a nice cold beer? Or how about having a nice cold one with some friends after work at a local bar, sounds nice right? Beer has been around for many years and will likely exist for many more. A beer is any variety of alcoholic beverage produced by the fermentation of starchy material derived from grains or other plant sources. The production of beer and some other alcoholic beverages is often called brewing. Almost every culture has its own tradition and approach to beer, thus producing many different styles and variations. Simply put, a beer style is a label given to a beer that describes its overall character and often its origin. It's a badge that has been earned over many centuries of brewing, trial and error, marketing and consumer acceptance. There are many different types of beer, each of which is said to belong to a particular style. Beer style is a label that describes the overall flavor and often origin of a beer, according to a system that has evolved through trial and error over many centuries. Depending on the type of yeast used in the beer fermentation process, most beer styles fall into one of two broad families: ale or lager. Beers that blend the characteristics of ales and lagers are called hybrids. An ale is any beer brewed using only top-fermenting yeasts and typically at higher temperatures than lager yeast. Because brewing yeasts cannot fully ferment some sugars, they produce esters in addition to alcohol and the result is a more flavorful beer with a slightly "flowery" or "fruity" aroma reminiscent of but not limited to apple, pear, pineapple, grass, hay. , plum or dried plum. The stylistic differences between ales are more varied than those found among lagers, and many ale styles are difficult to classify. Top-fermented beers, particularly popular in the British Isles, include barley wine, bitters, pale ale, porter and stout. The stylistic differences between top-fermented beers are decidedly more varied than those found among bottom-fermented beers, and many beer styles are difficult to categorize. California Common beer, for example, is brewed using a lager yeast at beer temperature. Wheat beers are often brewed using an ale yeast and then lagered, sometimes with a lager yeast. Lambics use wild yeasts and bacteria, naturally present in the Payottenland region of Belgium.
