fundamental chemical procedures of brewing, wine-making, and 8 / Introduction the intentional fermentation of alcoholic beverages (chapter 5). Although these events are impossible to date precisely, chemical analyses of pot- tery vessels indicate wine-making as early as 7000 BCE. Alcohol pro- duction rapidly became an important feature of human social life. Its relevance intensifi ed when improvements in crop productivity and the invention of distillation (probably fi rst in China before 200 CE, but only broadly disseminated by 700 CE) rendered high

instance concentrating on the grape-growing, wine-making, mind-expanding powers associated with the god Dionysus, from whom the Ptolemies had begun claiming ancestral descent. In honor of Dionysus, the parade was opened by actors dressed as the god’s companions and allies, the older Sileni (who restrained the crowds) and the youthful Satyrs (wearing artificial tails and outrageously large phalluses and carrying torches of gilded ivy). Next came incense—aromatic clouds of frankincense, myrrh, and saffron wafted into the air—fol- lowed by more costumed actors

incipient crafts of brewing, wine-making, and other modes of alcohol production were in full swing, in other words, as early civiliza- tions arose throughout the Old World. But unlike the fermentation of ripe fruits with abundant simple sugars, the use of grains such as barley, sorghum, millet, and rice requires an additional biochemical agent to break down complex carbohydrates into the smaller sugar molecules used by yeast cells. This process (technically known as saccharifi cation) can be accomplished through the use of specialized molds, as is done today for

were responsible for many of the diseases that afflict humans and domestic animals, and was first to show how im- munization by vaccination could prevent diseases like anthrax and rabies. Winemaking was very important to the French economy in the 1800s. It was com- mon knowledge that during aging, the inside surface of vats became coated with a hard crust. When the compound that formed the crust was isolated and purified, it produced tiny white crystals called tartaric acid, from the word tartaron that the Greeks used to describe the same crust 2,000 years

we know of yeasts and alcohol production originated in the cultural processes of brewing and wine-making, as developed over millennia. Now, by using yeast to ferment mostly corn, wheat, and sugar cane, humans produce about thirty billion liters of alcohol every year. This amount represents the second-largest biotechnological prod- uct in the world, exceeded only by the harvest of both farmed and nat- ural timber. About a quarter of our eff orts in fermentation goes towards alcoholic beverages, and the remainder is used as industrial alcohol and motor fuel
