WEBVTT 00:00:06.794 --> 00:00:12.118 This chimpanzee stumbles across a windfall of overripe plums. 00:00:12.118 --> 00:00:14.081 Many of them have split open, 00:00:14.081 --> 00:00:17.601 drawing him to their intoxicating fruity odor. 00:00:17.601 --> 00:00:19.032 He gorges himself 00:00:19.032 --> 00:00:23.042 and begins to experience some… strange effects. 00:00:23.042 --> 00:00:26.032 This unwitting ape has stumbled on a process 00:00:26.032 --> 00:00:28.179 that humans will eventually harness 00:00:28.179 --> 00:00:33.192 to create beer, wine, and other alcoholic drinks. NOTE Paragraph 00:00:33.192 --> 00:00:37.438 The sugars in overripe fruit attract microscopic organisms 00:00:37.438 --> 00:00:38.878 known as yeasts. 00:00:38.878 --> 00:00:43.781 As the yeasts feed on the fruit sugars they produce a compound called ethanol— 00:00:43.781 --> 00:00:46.791 the type of alcohol in alcoholic beverages. 00:00:46.791 --> 00:00:49.766 This process is called fermentation. 00:00:49.766 --> 00:00:51.861 Nobody knows exactly when 00:00:51.861 --> 00:00:54.611 humans began to create fermented beverages. 00:00:54.611 --> 00:00:59.572 The earliest known evidence comes from 7,000 BCE in China, 00:00:59.572 --> 00:01:01.682 where residue in clay pots 00:01:01.682 --> 00:01:04.875 has revealed that people were making an alcoholic beverage 00:01:04.875 --> 00:01:09.311 from fermented rice, millet, grapes, and honey. NOTE Paragraph 00:01:09.311 --> 00:01:11.111 Within a few thousand years, 00:01:11.111 --> 00:01:15.441 cultures all over the world were fermenting their own drinks. 00:01:15.441 --> 00:01:19.663 Ancient Mesopotamians and Egyptians made beer throughout the year 00:01:19.663 --> 00:01:21.919 from stored cereal grains. 00:01:21.919 --> 00:01:24.837 This beer was available to all social classes, 00:01:24.837 --> 00:01:28.232 and workers even received it in their daily rations. 00:01:28.232 --> 00:01:29.922 They also made wine, 00:01:29.922 --> 00:01:32.882 but because the climate wasn’t ideal for growing grapes, 00:01:32.882 --> 00:01:36.212 it was a rare and expensive delicacy. NOTE Paragraph 00:01:36.212 --> 00:01:40.162 By contrast, in Greece and Rome, where grapes grew more easily, 00:01:40.162 --> 00:01:45.072 wine was as readily available as beer was in Egypt and Mesopotamia. 00:01:45.072 --> 00:01:48.702 Because yeasts will ferment basically any plant sugars, 00:01:48.702 --> 00:01:50.625 ancient peoples made alcohol 00:01:50.625 --> 00:01:53.995 from whatever crops and plants grew where they lived. 00:01:53.995 --> 00:01:57.195 In South America, people made chicha from grains, 00:01:57.195 --> 00:01:59.912 sometimes adding hallucinogenic herbs. 00:01:59.912 --> 00:02:03.806 In what’s now Mexico, pulque, made from cactus sap, 00:02:03.806 --> 00:02:05.316 was the drink of choice, 00:02:05.316 --> 00:02:09.476 while East Africans made banana and palm beer. 00:02:09.476 --> 00:02:13.916 And in the area that’s now Japan, people made sake from rice. 00:02:13.916 --> 00:02:17.689 Almost every region of the globe had its own fermented drinks. NOTE Paragraph 00:02:17.689 --> 00:02:21.125 As alcohol consumption became part of everyday life, 00:02:21.125 --> 00:02:25.680 some authorities latched onto effects they perceived as positive— 00:02:25.680 --> 00:02:28.920 Greek physicians considered wine to be good for health, 00:02:28.920 --> 00:02:32.305 and poets testified to its creative qualities. 00:02:32.305 --> 00:02:36.427 Others were more concerned about alcohol’s potential for abuse. 00:02:36.427 --> 00:02:38.970 Greek philosophers promoted temperance. 00:02:38.970 --> 00:02:43.547 Early Jewish and Christian writers in Europe integrated wine into rituals 00:02:43.547 --> 00:02:46.936 but considered excessive intoxication a sin. 00:02:46.936 --> 00:02:49.715 And in the middle east, Africa, and Spain, 00:02:49.715 --> 00:02:52.691 an Islamic rule against praying while drunk 00:02:52.691 --> 00:02:57.052 gradually solidified into a general ban on alcohol. NOTE Paragraph 00:02:57.052 --> 00:03:01.613 Ancient fermented beverages had relatively low alcohol content. 00:03:01.613 --> 00:03:04.062 At about 13% alcohol, 00:03:04.062 --> 00:03:07.332 the by-products wild yeasts generate during fermentation 00:03:07.332 --> 00:03:09.692 become toxic and kill them. 00:03:09.692 --> 00:03:11.220 When the yeasts die, 00:03:11.220 --> 00:03:15.000 fermentation stops and the alcohol content levels off. 00:03:15.000 --> 00:03:18.900 So for thousands of years, alcohol content was limited. 00:03:18.900 --> 00:03:21.234 That changed with the invention of a process 00:03:21.234 --> 00:03:22.834 called distillation. 00:03:22.834 --> 00:03:27.280 9th century Arabic writings describe boiling fermented liquids 00:03:27.280 --> 00:03:29.708 to vaporize the alcohol in them. 00:03:29.708 --> 00:03:32.681 Alcohol boils at a lower temperature than water, 00:03:32.681 --> 00:03:34.741 so it vaporizes first. 00:03:34.741 --> 00:03:39.490 Capture this vapor, cool it down, and what’s left is liquid alcohol 00:03:39.490 --> 00:03:43.800 much more concentrated than any fermented beverage. NOTE Paragraph 00:03:43.800 --> 00:03:47.992 At first, these stronger spirits were used for medicinal purposes. 00:03:47.992 --> 00:03:51.181 Then, spirits became an important trade commodity 00:03:51.181 --> 00:03:55.097 because, unlike beer and wine, they didn’t spoil. 00:03:55.097 --> 00:03:56.668 Rum made from sugar 00:03:56.668 --> 00:03:59.358 harvested in European colonies in the Caribbean 00:03:59.358 --> 00:04:01.375 became a staple for sailors 00:04:01.375 --> 00:04:03.595 and was traded to North America. 00:04:03.595 --> 00:04:06.663 Europeans brought brandy and gin to Africa 00:04:06.663 --> 00:04:09.581 and traded it for enslaved people, land, 00:04:09.581 --> 00:04:12.251 and goods like palm oil and rubber. 00:04:12.251 --> 00:04:16.001 Spirits became a form of money in these regions. NOTE Paragraph 00:04:16.001 --> 00:04:17.903 During the Age of Exploration, 00:04:17.903 --> 00:04:21.745 spirits played a crucial role in long distance sea voyages. 00:04:21.745 --> 00:04:25.677 Sailing from Europe to east Asia and the Americas could take months, 00:04:25.677 --> 00:04:28.848 and keeping water fresh for the crews was a challenge. 00:04:28.848 --> 00:04:33.728 Adding a bucket of brandy to a water barrel kept water fresh longer 00:04:33.728 --> 00:04:38.520 because alcohol is a preservative that kills harmful microbes. NOTE Paragraph 00:04:38.520 --> 00:04:40.320 So by the 1600s, 00:04:40.320 --> 00:04:43.890 alcohol had gone from simply giving animals a buzz 00:04:43.890 --> 00:04:49.754 to fueling global trade and exploration— along with all their consequences. 00:04:49.754 --> 00:04:50.999 As time went on, 00:04:50.999 --> 00:04:55.201 its role in human society would only get more complicated.
