communications 3 00:00:53,758 --> 00:00:55,206 Narrator: the word champagne 4 00:00:55,206 --> 00:00:59,241 Is often used to describe Sparkling white wines. 5 00:00:59,241 --> 00:01:02,379 But true champagne can only come From the champagne region 6 00:01:02,379 --> 00:01:04,413 Of france. 7 00:01:04,413 --> 00:01:06,896 It must meet a long list Of special requirements 8 00:01:06,896 --> 00:01:09,000 Before receiving The coveted label. 9 00:01:14,310 --> 00:01:17,482 The champagne industry Is heavily regulated. 10 00:01:17,482 --> 00:01:20,448 The grapes must be locally grown In the champagne region 11 00:01:20,448 --> 00:01:22,413 Of france. 12 00:01:22,413 --> 00:01:26,344 They can only use three types Of grapes, black pinot noir, 13 00:01:26,344 --> 00:01:27,551 Pinot meunier, 14 00:01:27,551 --> 00:01:32,034 Or white chardonnay, To produce champagne. 15 00:01:32,034 --> 00:01:34,068 Additional rules regulate How the grapes 16 00:01:34,068 --> 00:01:39,344 Can be pruned, picked, Pressed, fermented and aged. 17 00:01:39,344 --> 00:01:42,206 Workers harvest the grapes In mid-september. 18 00:01:42,206 --> 00:01:45,034 They use aerated crates To transfer the crops 19 00:01:45,034 --> 00:01:46,655 To a grape press. 20 00:01:46,655 --> 00:01:47,827 They crush the grapes 21 00:01:47,827 --> 00:01:50,000 And immediately filter The juice. 22 00:01:50,000 --> 00:01:53,413 The grape skins and pulp Can alter the juice's flavor, 23 00:01:53,413 --> 00:01:57,517 So they have to be removed Quickly. 24 00:01:57,517 --> 00:02:03,137 Vintage champagne is fermented In old oak barrels. 25 00:02:03,137 --> 00:02:05,655 They use a sulfur disk To disinfect the barrels 26 00:02:05,655 --> 00:02:07,586 Between uses. 27 00:02:07,586 --> 00:02:10,241 First, a worker Lights the disk and inserts 28 00:02:10,241 --> 00:02:12,000 It through a hole on the side. 29 00:02:12,000 --> 00:02:15,034 The flame goes out once It's sealed inside the barrel. 30 00:02:15,034 --> 00:02:16,862 The sulfur smoke Fills the barrel 31 00:02:16,862 --> 00:02:19,275 And kills off any bacteria. 32 00:02:19,275 --> 00:02:20,793 Non-vintage champagnes 33 00:02:20,793 --> 00:02:23,517 Are produced In these stainless steel tanks. 34 00:02:23,517 --> 00:02:26,551 They start the fermentation Process by adding yeast 35 00:02:26,551 --> 00:02:28,482 To the grape juice. 36 00:02:28,482 --> 00:02:30,413 In about 10 days, the yeast 37 00:02:30,413 --> 00:02:36,034 Turns the sugar into alcohol And carbon dioxide gas. 38 00:02:36,034 --> 00:02:40,206 The alcohol level of the wine Is now about 10 1/2 percent. 39 00:02:40,206 --> 00:02:41,586 There are no bubbles yet 40 00:02:41,586 --> 00:02:46,931 Because the co2 escaped Through the top of the tank. 41 00:02:46,931 --> 00:02:49,379 Each fermentation barrel And tank 42 00:02:49,379 --> 00:02:53,068 Is labeled based on where The juice inside originated. 43 00:02:53,068 --> 00:02:56,413 The grape juices from each Village have distinctive tastes, 44 00:02:56,413 --> 00:03:01,931 Caused by differences in soil Composition and sun exposure. 45 00:03:01,931 --> 00:03:05,448 Blending begins After the first fermentation. 46 00:03:05,448 --> 00:03:09,034 The winery's experts experiment With different combinations 47 00:03:09,034 --> 00:03:13,206 Until they find the taste And aroma they're looking for. 48 00:03:13,206 --> 00:03:16,068 They bottle the mixture With yeast and sugar, 49 00:03:16,068 --> 00:03:19,620 And place it in a cold, Damp cellar for 5 weeks. 50 00:03:19,620 --> 00:03:22,586 This second fermentation Raises the alcohol content 51 00:03:22,586 --> 00:03:25,965 To 12 1/2 percent. 52 00:03:25,965 --> 00:03:27,344 After fermentation, 53 00:03:27,344 --> 00:03:29,620 They lie the bottles Down horizontally 54 00:03:29,620 --> 00:03:34,517 And let the champagne age For up to 10 years. 55 00:03:34,517 --> 00:03:35,896 After the aging, 56 00:03:35,896 --> 00:03:39,068 The bottles go into a machine That freezes the neck. 57 00:03:39,068 --> 00:03:44,275 The yeast residue freezes in A small ice cube under the cork. 58 00:03:44,275 --> 00:03:49,000 The carbon dioxide is invented During the second fermentation. 59 00:03:49,000 --> 00:03:50,758 When workers open each bottle, 60 00:03:50,758 --> 00:03:53,758 The gas pressure Ejects the ice cube. 61 00:03:53,758 --> 00:03:56,931 This procedure is called Disgorging. 62 00:03:56,931 --> 00:03:58,448 A worker turns the bottle 63 00:03:58,448 --> 00:04:01,620 To minimize the amount Of champagne that escapes. 64 00:04:01,620 --> 00:04:06,655 Then he smells it to make sure The champagne hasn't spoiled. 65 00:04:06,655 --> 00:04:08,413 The winery 66 00:04:08,413 --> 00:04:11,655 Makes a special liqueur Out of wine and cane sugar, 67 00:04:11,655 --> 00:04:14,068 Which they add to the champagne. 68 00:04:14,068 --> 00:04:17,034 The amount of liqueur added Brings the champagne to one 69 00:04:17,034 --> 00:04:18,689 Of three sweetness levels, 70 00:04:18,689 --> 00:04:20,413 Known as brut, sec, 71 00:04:20,413 --> 00:04:22,137 Or demi-sec. 72 00:04:22,137 --> 00:04:26,379 The filling machine secures The new cork with a wire cap. 73 00:04:26,379 --> 00:04:30,379 The next machine rotate the Bottles to mix in the liqueur. 74 00:04:30,379 --> 00:04:32,206 Then the bottles Go into the cellar 75 00:04:32,206 --> 00:04:34,689 For at least 3 months. 76 00:04:34,689 --> 00:04:36,310 After they come Out of the cellar, 77 00:04:36,310 --> 00:04:40,655 The bottles go through An automated washing machine. 78 00:04:40,655 --> 00:04:43,896 A worker inspects every bottle For floating cork particles 79 00:04:43,896 --> 00:04:47,448 Or flaws in the glass. 80 00:04:47,448 --> 00:04:49,689 The labeling machine's First station places 81 00:04:49,689 --> 00:04:51,862 Gold foil over the neck. 82 00:04:51,862 --> 00:04:55,206 The foil label Bears the winery's name. 83 00:04:55,206 --> 00:04:58,068 The second station fires a shot Of compressed air 84 00:04:58,068 --> 00:05:00,482 To mold the foil To the shape of the cork. 85 00:05:06,103 --> 00:05:08,413 The third station glues On the neck label. 86 00:05:08,413 --> 00:05:13,172 It's made of varnished paper. 87 00:05:13,172 --> 00:05:14,551 Then, the last station 88 00:05:14,551 --> 00:05:19,103 Applies an adhesive label To the front of the bottle. 89 00:05:19,103 --> 00:05:20,724 A scanner makes sure the foil 90 00:05:20,724 --> 00:05:23,241 And labels Are in the correct place. 91 00:05:28,206 --> 00:05:33,172 This bottle of champagne Is finally ready to drink. 92 00:05:33,172 --> 00:05:38,275 When you pop the cork, the gas Trapped inside gently escapes. 93 00:05:38,275 --> 00:05:40,241 Shaking the bottle Just before opening 94 00:05:40,241 --> 00:05:44,689 Will cause an even more dramatic Champagne explosion. 95 00:05:44,689 --> 00:05:48,758 Either way, it's the perfect Drink to celebrate any occasion. 96 00:05:48,758 --> 00:05:50,758 Cheers. 97 00:06:02,448 --> 00:06:04,620 Narrator: before the automated Teller machine, 98 00:06:04,620 --> 00:06:07,482 Withdrawals and deposits Were made in person. 99 00:06:07,482 --> 00:06:09,275 Then, in the 1960s, 100 00:06:09,275 --> 00:06:12,896 Simple cash machines started To appear all over europe. 101 00:06:12,896 --> 00:06:16,000 Later, more sophisticated Versions were developed. 102 00:06:16,000 --> 00:06:18,517 Today's atms Make it easy and convenient 103 00:06:18,517 --> 00:06:22,793 To bank outside Of normal business hours. 104 00:06:22,793 --> 00:06:25,310 Atms are made of two sections. 105 00:06:25,310 --> 00:06:29,103 The bottom is a steel safe That houses the cash dispenser. 106 00:06:29,103 --> 00:06:33,517 The head module contains All the user features on top. 107 00:06:33,517 --> 00:06:38,793 Most of the atm's non-electronic Parts are cut from steel sheets. 108 00:06:38,793 --> 00:06:40,310 Workers load the steel sheets 109 00:06:40,310 --> 00:06:42,724 Into a computer-guided Laser cutting machine. 110 00:06:42,724 --> 00:06:46,965 The laser uses focused light To generate intense heat. 111 00:06:46,965 --> 00:06:49,827 The heat melts the steel To make the cuts. 112 00:06:53,344 --> 00:06:56,448 The simpler parts are stamped With a die and a press. 113 00:07:01,413 --> 00:07:03,034 Next, a robot loads 114 00:07:03,034 --> 00:07:06,758 The piece into a fully-automated Computer-guided bending press. 115 00:07:06,758 --> 00:07:09,758 The press bends the part Into the required shape. 116 00:07:21,034 --> 00:07:22,862 A computer guided spot welder 117 00:07:22,862 --> 00:07:26,482 Fuses the simple parts Together at set intervals. 118 00:07:26,482 --> 00:07:28,137 For more complex parts, 119 00:07:28,137 --> 00:07:32,172 A computer guided 3-d laser Welds the entire joint. 120 00:07:37,206 --> 00:07:38,965 An automated transport system 121 00:07:38,965 --> 00:07:41,137 Dips the steel parts In a metal primer 122 00:07:41,137 --> 00:07:44,103 To prevent corrosion. 123 00:07:44,103 --> 00:07:48,655 After dipping, They dry the parts in an oven. 124 00:07:48,655 --> 00:07:51,896 The housing parts are sprayed With liquid or powder paint. 125 00:07:54,758 --> 00:07:58,413 Then they go into an oven To bake on the color. 126 00:07:58,413 --> 00:08:02,758 This is the internal structure For the atm's head module. 127 00:08:02,758 --> 00:08:05,965 Workers assemble all the Module's internal components, 128 00:08:05,965 --> 00:08:10,137 Including the power unit And the atm's computer. 129 00:08:10,137 --> 00:08:13,758 Then, they lower the head module Onto the atm's steel safe. 130 00:08:16,413 --> 00:08:19,068 The safe's walls Can be up to 2 inches thick. 131 00:08:21,965 --> 00:08:25,379 There's a separate assembly line For the operation panel. 132 00:08:25,379 --> 00:08:28,275 This panel goes on the front Of the head module. 133 00:08:28,275 --> 00:08:31,758 It contains everything used In an atm transaction, 134 00:08:31,758 --> 00:08:33,793 From the card reader, To the key pad, 135 00:08:33,793 --> 00:08:35,586 And even the speaker system. 136 00:08:39,379 --> 00:08:42,793 The key pad encrypts the user's Personal identification number 137 00:08:42,793 --> 00:08:47,551 Inside the atm. 138 00:08:47,551 --> 00:08:50,620 The machine has up To three security cameras. 139 00:08:50,620 --> 00:08:55,758 They record the key pad, The cash tray and the atm user. 140 00:08:55,758 --> 00:08:59,344 Workers connect the monitor To the internal computer. 141 00:08:59,344 --> 00:09:03,758 They also install the card Reader and the receipt slot. 142 00:09:03,758 --> 00:09:05,344 At the bank's request, 143 00:09:05,344 --> 00:09:08,517 They can install A separate module for deposits. 144 00:09:08,517 --> 00:09:12,551 However, this atm uses the cash Out slot to accept deposits. 145 00:09:16,862 --> 00:09:19,275 Workers also install The shutter, 146 00:09:19,275 --> 00:09:22,413 A computer-controlled flap On the cash out slot. 147 00:09:22,413 --> 00:09:24,620 It opens when the machine Accepts a deposit 148 00:09:24,620 --> 00:09:28,793 Or dispenses money. 149 00:09:28,793 --> 00:09:31,413 Next, workers Mount the operation panel 150 00:09:31,413 --> 00:09:34,448 To the head module. 151 00:09:34,448 --> 00:09:35,931 On a separate assembly line, 152 00:09:35,931 --> 00:09:39,379 They prepare the electronic Mechanical unit. 153 00:09:39,379 --> 00:09:40,827 It dispenses the money 154 00:09:40,827 --> 00:09:43,379 And accepts cash And checks for deposits. 155 00:09:47,965 --> 00:09:52,172 Workers load cassettes into the Unit for each cash denomination. 156 00:09:52,172 --> 00:09:57,034 The bank will separate and stock The cash for their atm. 157 00:09:57,034 --> 00:09:59,379 Before they install the unit In the atm, 158 00:09:59,379 --> 00:10:01,551 They hook it up To a test computer. 159 00:10:01,551 --> 00:10:04,931 They test a few different Transactions with fake bills 160 00:10:04,931 --> 00:10:07,310 To make sure It dispenses the correct amount. 161 00:10:10,931 --> 00:10:12,896 If the unit passes testing, 162 00:10:12,896 --> 00:10:15,482 Workers Install it in the atm safe. 163 00:10:20,000 --> 00:10:22,000 They run a couple Of the finished machines 164 00:10:22,000 --> 00:10:27,379 Through several Quality control tests. 165 00:10:27,379 --> 00:10:29,379 First, a shake test 166 00:10:29,379 --> 00:10:34,172 Ensures the atm can withstand A bumpy ride during transport. 167 00:10:34,172 --> 00:10:36,310 Next, they conduct a shower test 168 00:10:36,310 --> 00:10:40,310 To ensure that rain Won't damage an outdoor atm. 169 00:10:40,310 --> 00:10:42,310 There's also a climate test. 170 00:10:42,310 --> 00:10:45,793 They place the atm in a chamber That simulates temperature 171 00:10:45,793 --> 00:10:50,793 Ranging from negative 40 degrees To over 120 degrees fahrenheit. 172 00:10:50,793 --> 00:10:53,379 Atms designed For extreme temperatures 173 00:10:53,379 --> 00:10:57,172 Usually have built-in heating Or cooling systems. 174 00:10:57,172 --> 00:11:01,551 Every atm comes with basic Operating software installed. 175 00:11:01,551 --> 00:11:04,413 The banks then Install their custom software 176 00:11:04,413 --> 00:11:08,034 Or have the manufacturer Do it for them. 177 00:11:17,379 --> 00:11:20,172 It takes a powerful engine To
