WEBVTT 00:00:07.034 --> 00:00:09.594 Before empires and royalty, 00:00:09.594 --> 00:00:11.764 before pottery and writing, 00:00:11.764 --> 00:00:14.304 before metal tools and weapons – 00:00:14.304 --> 00:00:16.094 there was cheese. 00:00:16.094 --> 00:00:18.974 As early as 8000 BCE, 00:00:18.974 --> 00:00:23.044 the earliest Neolithic farmers living in the Fertile Crescent 00:00:23.044 --> 00:00:25.474 began a legacy of cheesemaking 00:00:25.474 --> 00:00:29.184 almost as old as civilization itself. 00:00:29.184 --> 00:00:33.200 The rise of agriculture led to domesticated sheep and goats, 00:00:33.200 --> 00:00:36.110 which ancient farmers harvested for milk. 00:00:36.110 --> 00:00:39.540 But when left in warm conditions for several hours, 00:00:39.540 --> 00:00:42.160 that fresh milk began to sour. 00:00:42.160 --> 00:00:47.740 Its lactic acids caused proteins to coagulate, binding into soft clumps. 00:00:47.740 --> 00:00:50.520 Upon discovering this strange transformation, 00:00:50.520 --> 00:00:53.150 the farmers drained the remaining liquid – 00:00:53.150 --> 00:00:54.760 later named whey – 00:00:54.760 --> 00:01:01.510 and found the yellowish globs could be eaten fresh as a soft, spreadable meal. 00:01:01.512 --> 00:01:05.942 These clumps, or curds, became the building blocks of cheese, 00:01:05.942 --> 00:01:10.602 which would eventually be aged, pressed, ripened, and whizzed 00:01:10.602 --> 00:01:15.122 into a diverse cornucopia of dairy delights. NOTE Paragraph 00:01:15.122 --> 00:01:19.728 The discovery of cheese gave Neolithic people an enormous survival advantage. 00:01:19.728 --> 00:01:24.468 Milk was rich with essential proteins, fats, and minerals. 00:01:24.468 --> 00:01:28.148 But it also contained high quantities of lactose – 00:01:28.148 --> 00:01:33.418 a sugar which is difficult to process for many ancient and modern stomachs. 00:01:33.418 --> 00:01:39.128 Cheese, however, could provide all of milk’s advantages with much less lactose. 00:01:39.128 --> 00:01:42.088 And since it could be preserved and stockpiled, 00:01:42.088 --> 00:01:44.478 these essential nutrients could be eaten 00:01:44.478 --> 00:01:48.428 throughout scarce famines and long winters. 00:01:48.428 --> 00:01:52.560 Some 7th millennium BCE pottery fragments found in Turkey 00:01:52.560 --> 00:01:57.290 still contain telltale residues of the cheese and butter they held. NOTE Paragraph 00:01:57.290 --> 00:01:58.990 By the end of the Bronze Age, 00:01:58.990 --> 00:02:02.050 cheese was a standard commodity in maritime trade 00:02:02.050 --> 00:02:04.480 throughout the eastern Mediterranean. 00:02:04.480 --> 00:02:07.700 In the densely populated city-states of Mesopotamia, 00:02:07.700 --> 00:02:11.250 cheese became a staple of culinary and religious life. 00:02:11.250 --> 00:02:13.250 Some of the earliest known writing 00:02:13.250 --> 00:02:16.340 includes administrative records of cheese quotas, 00:02:16.340 --> 00:02:20.440 listing a variety of cheeses for different rituals and populations 00:02:20.440 --> 00:02:22.215 across Mesopotamia. 00:02:22.215 --> 00:02:27.345 Records from nearby civilizations in Turkey also reference rennet. 00:02:27.345 --> 00:02:31.340 This animal byproduct, produced in the stomachs of certain mammals, 00:02:31.340 --> 00:02:35.505 can accelerate and control coagulation. 00:02:35.505 --> 00:02:40.225 Eventually this sophisticated cheesemaking tool spread around the globe, 00:02:40.225 --> 00:02:44.185 giving way to a wide variety of new, harder cheeses. 00:02:44.185 --> 00:02:48.245 And though some conservative food cultures rejected the dairy delicacy, 00:02:48.245 --> 00:02:54.105 many more embraced cheese, and quickly added their own local flavors. NOTE Paragraph 00:02:54.105 --> 00:03:00.882 Nomadic Mongolians used yaks’ milk to create hard, sundried wedges of Byaslag. 00:03:00.882 --> 00:03:07.293 Egyptians enjoyed goats’ milk cottage cheese, straining the whey with reed mats. 00:03:07.293 --> 00:03:11.623 In South Asia, milk was coagulated with a variety of food acids, 00:03:11.623 --> 00:03:14.633 such as lemon juice, vinegar, or yogurt 00:03:14.633 --> 00:03:18.303 and then hung to dry into loafs of paneer. 00:03:18.303 --> 00:03:22.223 This soft mild cheese could be added to curries and sauces, 00:03:22.223 --> 00:03:25.903 or simply fried as a quick vegetarian dish. 00:03:25.903 --> 00:03:29.903 The Greeks produced bricks of salty brined feta cheese, 00:03:29.903 --> 00:03:34.563 alongside a harder variety similar to today’s pecorino romano. 00:03:34.563 --> 00:03:37.178 This grating cheese was produced in Sicily 00:03:37.178 --> 00:03:41.158 and used in dishes all across the Mediterranean. 00:03:41.158 --> 00:03:45.297 Under Roman rule, “dry cheese” or “caseus aridus,” 00:03:45.297 --> 00:03:46.857 became an essential ration 00:03:46.857 --> 00:03:53.397 for the nearly 500,000 soldiers guarding the vast borders of the Roman Empire. NOTE Paragraph 00:03:53.397 --> 00:03:56.238 And when the Western Roman Empire collapsed, 00:03:56.238 --> 00:03:58.308 cheesemaking continued to evolve 00:03:58.308 --> 00:04:02.388 in the manors that dotted the medieval European countryside. 00:04:02.388 --> 00:04:06.362 In the hundreds of Benedictine monasteries scattered across Europe, 00:04:06.362 --> 00:04:10.872 medieval monks experimented endlessly with different types of milk, 00:04:10.872 --> 00:04:12.222 cheesemaking practices, 00:04:12.222 --> 00:04:17.202 and aging processes that led to many of today’s popular cheeses. 00:04:17.202 --> 00:04:20.955 Parmesan, Roquefort, Munster and several Swiss types 00:04:20.955 --> 00:04:26.085 were all refined and perfected by these cheesemaking clergymen. 00:04:26.085 --> 00:04:29.815 In the Alps, Swiss cheesemaking was particularly successful – 00:04:29.815 --> 00:04:32.897 producing a myriad of cow’s milk cheeses. 00:04:32.897 --> 00:04:34.737 By the end of the 14th century, 00:04:34.737 --> 00:04:39.727 Alpine cheese from the Gruyere region of Switzerland had become so profitable 00:04:39.727 --> 00:04:43.097 that a neighboring state invaded the Gruyere highlands 00:04:43.097 --> 00:04:46.507 to take control of the growing cheese trade. NOTE Paragraph 00:04:46.507 --> 00:04:49.237 Cheese remained popular through the Renaissance, 00:04:49.237 --> 00:04:52.977 and the Industrial Revolution took production out of the monastery 00:04:52.977 --> 00:04:54.587 and into machinery. 00:04:54.587 --> 00:04:59.647 Today, the world produces roughly 22 billion kilograms of cheese a year, 00:04:59.647 --> 00:05:02.327 shipped and consumed around the globe. 00:05:02.327 --> 00:05:05.097 But 10,000 years after its invention, 00:05:05.097 --> 00:05:10.377 local farms are still following in the footsteps of their Neolithic ancestors, 00:05:10.377 --> 00:05:14.457 hand crafting one of humanity’s oldest and favorite foods.
