User: What is the difference between craft beer and regular beer?
Assistant: Beer goes through a variety of stages that depend on the type and style of beer that’s being produced.  Almost all beers follow what are known as the “four stages of fermentation.”  Generally speaking, the process follows these stages: primary fermentation, conditioning, maturation, and storage.  The craft beer movement refers to beers that have been brewed at smaller breweries.  These beers tend to use different methods and ingredients from regular beers.  Often, the types of hops, grains, and malts used in the brewing process are more unusual.  There are also ongoing trends toward using different recipes and brewing methods, which can create beers with unusual flavors.  A craft brew may also have more complex flavors than a regular, commercial beer.
