Beer

There are all sorts of different types of beer, from light and refreshing lagers to hearty stouts and ales. But broadly speaking, beers can be classified into two categories: ales and lagers. Ales are brewed with top-fermenting yeast strains that rise to the top of the fermentation tank, while lagers are brewed with bottom-fermenting yeast strains that sink to the bottom. This difference in yeast strain leads to a difference in flavour profile, with ales typically being fruity and complex, while lagers are cleaner tasting and more refreshing.

Most beer is brewed with a four-step process. malted barley is mixed with hot water to create a sweet liquid called 'wort'. Hops are added to the wort, and the mixture is boiled. Yeast is then added, and the beer ferments. Finally, the beer is bottled or kegged and refrigerated. There are many different types of beer, each with its own unique brewing process. For example, lager beers are brewed at colder temperatures than ales, and porters are brewed with darker malts than blonde beers. Brewers use a variety of techniques to make different types of beer. For example, some brewers add roasted malts or other grains to the wort (unfermented beer), while others add fruit or spices. Fermentation also produces carbon dioxide gas, which gives beer its fizzy character.
