Microbrews are brewed by tiny breweries inside the bottle. The brewery is built and dedicated inside of each bottle then filled with water, soil and hop seeds and barley nuts. The micro brewers then get to action planting, growing and harvesting the grains. After they are harvested, the grains are just left out to ferment in the water. The micro brewers die...most of the time. It isn't unheard of for a micro brewer to remain alive in the stomach, continuously making beer, producing constant intoxication.
