Hi! I work at a brewery in the finance department. What about you?
brewery or brewing company is a business,who sells beer 
That's interesting, what kind of beer?
microbrewery or craft brewery is a brewery that produces small amounts of beer
Really? How much beer do microbreweries produce?
traced back almost 5000 years to Mesopotamian writings describing daily rations of beer
I see. How much beer were they rationed?
Rationing
Rationing is the controlled distribution of scarce resources, goods, services, or an artificial restriction of demand. Rationing controls the size of the ration, which is one's allowed portion of the resources being distributed on a particular day or at a particular time. There are many forms of rationing, and in western civilization people experience some of them in daily life without realizing it.
Rationing is often done to keep price below the equilibrium (market-clearing) price determined by the process of supply and demand in
Microbrewery
A microbrewery or craft brewery is a brewery that produces small amounts of beer, typically much smaller than large-scale corporate breweries, and is independently owned. Such breweries are generally characterized by their emphasis on quality, flavor and brewing technique.
The microbrewing movement began in the United Kingdom in the 1970s, although traditional artisanal brewing existed in Europe for centuries and subsequently spread to other countries. As the movement grew, and some breweries expanded their production and distribution, the more encompassing concept of craft brewing emerged.
