Introduction to Craft Beer
The craft beer is a type of fine brewing beer, varying from regular beer or industry beer.
When regular beer or industry beer is brewed, the malt is mostly replaced by rice, corn, starch and other ingredients in order to reduce the cost. But craft beer is brewed using malt, hops, yeast and water without any artificial additives. Normally it is brewed without much consideration of cost. Most craft beer is brewed with high quality ingredients with a variety of tastes and flavors, which can be changed according to one’s own taste.
Apart from fine ingredients, craft beer also features its scientific brewing formulas and advanced technologies. The brewing formulas focus on the characteristics of ingredients itself and brewers’ comprehension towards craft beer. At the same time, the brewing technologies utilize some special methods and processes such as cold dry-hopping.

Where does the Bitterness of Craft Beer Come from?
The bitterness of craft beer is from hops. Hops contain a kind of α-acid. The molecular structure of α-acid changes after boiling at a high temperature, turning into a kind of bitter isomerism α-acid that is capable of providing bitterness balancing out the sugar in the wort. It is not that the more bitter the beer, the better. The degree of bitterness should be appropriate.
How Many Kinds of Beer are There?
In terms of fermentation methods, beer falls into two main categories.
1. Ale: Ale is made with top-fermenting yeast with a shorter fermenting time. Ale always have an intense taste and appealing appearance. During the warm fermenting process, Ale can develop a great variety of fatty flavors, with flavors of nutty, fruit, even chocolate and honey if malt is processed well.
2. Lager: Lager is made with bottom-fermenting yeast, and then should be stored at a low temperature, which has a longer fermenting time than Ale. Now the beer produced in China is almost Lager.
The craft beer is mostly Ale. The yeast works at the top of fermentation tanks, floating above the liquor.
