  • Melitta Bentz's Company: WWI Zeppelin Shortages, Red-Green Box, Paid Leave

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Amalie Auguste Melitta Liebscher was born in Dresden in January 1873 to a book publisher, with grandparents who owned a brewery. Married to Hugo Bentz and raising Willi, Horst, and Herta, she was fed up with bitter coffee from percolators, slow gritty early espresso filters, and stained linen bags. She punched holes in a brass pot with a nail, lined it with blotting paper from her son's school notebook, and in June 1908 won a patent in Berlin. The family founded the company that year, with Hugo making filters and Melitta selling them through shop window demonstrations and coffee afternoons.

    World War I nearly ended it. Hugo and Willi were drafted, her brother Paul Liebscher stepped in, metals went to zeppelins, paper was rationed, and the British blockade cut off coffee, so the company went dormant. It revived in the 1920s despite inflation, with Willi becoming co-owner in 1923, and in 1929 it moved from Dresden to a factory in Minden that still operates. The cone filter followed in 1932, the year Melitta and Hugo handed the business to their children.

    • The red and green packaging arrived in 1925 to set genuine filters apart from knockoffs.
    • The Melitta script logo was introduced in 1932 and finalized in 1937.
    • She gave workers a five day week, three weeks of paid vacation, and Christmas bonuses, and set up the Melitta Aid social fund in 1938.
    • During World War II filter production stopped and the factory was designated a National Socialist Model Plant making military supplies.
    • She died on June 29, 1950, in Porta Westfalica.

  • Joel Cheek's Maxwell House: A Free 20-Pound Sample, a Fake Roosevelt Line

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Joel Owsley Cheek moved to Nashville in 1884 as a coffee broker and teamed up with British broker Roger Nolley Smith, who could name a green bean's origin by smell. After years of blending, in 1892 Cheek gave 20 pounds of coffee free to the buyer at the Maxwell House Hotel. When it ran out and the hotel went back to its cheaper brand, guests complained, the hotel bought Cheek's blend exclusively, and within six months it let him use its name. Cheek quit brokering and, with partner Maxwell Colbourne, built what became the Cheek-Neal Coffee Company.

    The company began using Good to the last drop in 1915, and General Foods bought it in 1925. In the 1930s General Foods claimed Theodore Roosevelt coined the line at the Hermitage in October 1907, a story made up by former General Foods president Clifford Spiller. Roosevelt did visit and drink coffee there, but reportedly said it was the kind of stuff he liked to drink when he hunted bears. The brand kept the tale going, even hiring a Roosevelt impersonator for a 2009 commercial.

    • In 1932 ad man Joseph Jacobs had a rabbi certify coffee kosher for Passover as a berry, which led to the free Maxwell House Haggadah.
    • Barack Obama used the Maxwell House Haggadah at White House Seders from 2009 to 2016.
    • The brand sponsored the CBS show Mama from 1949 to 1957, and later Margaret Hamilton played shopkeeper Cora in its ads.
    • Michael Caine saw Shakira Baksh in a 1971 Brazilian Maxwell House commercial, tracked her down in London, and married her in 1973.
    • Instant coffee supplied to World War II troops reached civilian shelves in the fall of 1945.

  • Kopitiam Culture: Margarine-Roasted Robusta, Ipoh White Coffee, and Halal

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Kopitiam joins the Malay word kopi, coffee, with the Hokkien tiam, shop, and the name maps the Chinese communities who opened them across Indonesia, Malaysia, Singapore, Brunei, and southern Thailand. Singapore has about 2,000. The owner usually runs the drink stall, with coffee, tea, soft boiled eggs, and kaya toast, and leases the other stalls to hawkers selling Hainanese chicken rice, nasi lemak, char kway teow, or Hokkien mee, so neighbors from different ethnic and dietary backgrounds share one set of tables.

    The coffee is Robusta, brought in by Arab traders as the working man's bean while Europeans favored Arabica. To tame its harshness, roasters added fat and sugar to the drum. Ipoh white coffee, from the Old Town district of Ipoh in Malaysia, uses palm oil margarine and less sugar, so the beans come out lighter. In Malaysia the term is narrower, meaning traditional Malaysian Chinese coffee shops, and more than 100 modern chains such as OldTown White Coffee have moved the format into air conditioned malls.

    • Famous Singapore names that began as neighborhood shops include Killiney, Tong Ah Eating House, and Ya Kun Kaya Toast.
    • In black kopi roasting, heavy sugar caramelizes and turns the beans nearly black.
    • Modern Malaysian chains went fully halal, cutting pork and separating prep areas so Muslim diners could join in.
    • The region's phrase coffee shop talk describes the gossip and political argument these shops are known for.
    • Malique, formerly of the hip hop duo Too Phat, satirized that rumor mill in a song whose title means coffee shop story.

  • La Marzocco: The Bambi Family's Horizontal Boiler and the Starbucks Deal

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Brothers Giuseppe and Bruno Bambi founded La Marzocco in Florence in 1927, naming it for the city's seated lion symbol after building a first machine, the Fiorenza, on commission. In 1939 they patented a horizontal boiler that laid the old vertical column on its side and set the brew groups in a row, so baristas could face customers. Giuseppe's son Piero joined in the early 1950s, and the Poker series of the 1960s replaced the lever with a diaphragm pushed by boiler steam.

    In 1970 the GS brought a dual boiler system, one for steam and one for brewing, plus a group head welded to the brew boiler so it stayed at temperature. In 1978 Kent Bakke and partners from a Pioneer Square cafe visited the factory and won rights to import the machines, and by 1988 his group supplied Starbucks. Piero's 1990 Linea arrived in time for the boom, Bakke's investors took a 90 percent stake in 1994 and opened a Seattle factory, and Starbucks used the machines until 2004.

    • Giuseppe's Vulcano grinder won a decorative and industrial arts prize in Milan in 1968.
    • Bakke's team once pushed an espresso machine on a cart at a Washington arts festival in 1979.
    • Machine names carry the family: the FB70 for the Fratelli Bambi, the GB5 for Giovanna Bambi, and the Linea PB for Piero.
    • Pressure profiling arrived in 2009, letting baristas ramp from gentle pre-infusion to nine bars and back down.
    • De'Longhi took a majority stake between 2021 and 2023, pairing it with Eversys, and the original shareholders kept 12 percent.

  • Java's Forced Coffee and Sugar: The Dutch Cultivation System, 1830 to 1870

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    The collapse of the Dutch East India Company in 1799 left its debts to the Dutch state. A land tax under Herman Willem Daendels and a short British occupation raised revenue on paper but squeezed Javanese farmers who lived on rice rather than cash. The Padri War, the Java War of 1825 to 1830, and the Belgian Revolution drained the treasury further, so in 1830 Governor General Johannes van den Bosch introduced the cultuurstelsel, which Indonesian historians call tanam paksa, enforced planting. Villages owed 20 percent of their land to export crops such as sugar, indigo, and coffee, or 66 days of labor.

    In practice farmers gave up far more, often the best irrigated plots, and travel passes tied them to their villages. Local middlemen earned commissions on crop volume, and the government paid in copper coins worth less than half their face value at a forced rate of two to one. The budget balanced by 1831 and the system at its peak supplied half of Dutch state revenue, while famine and epidemics in the 1840s spread from Cirebon into central Java and mortality rose as much as 30 percent.

    • At its peak the system involved up to one million farmers.
    • Writing in 1861, J.W.B. Money said the currency trick made Dutch loans worth double their amount in Java.
    • Critics such as Multatuli exposed the abuses, but merchant lobbying for private plantations drove the change.
    • The 1870 Sugar Law and Agrarian Law ended the formal system, and research estimates mortality would otherwise have run 20 percent higher.
    • Forced labor continued as penal work building railways, bridges, and irrigation for private estates.

  • James Dewar's Vacuum Flask: The Unpatented Invention That Became Thermos

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In 1892 Scottish scientist James Dewar needed to measure the specific heat of palladium at cryogenic temperatures, so he sealed one brass chamber inside another and pumped out the air between them. The vacuum stopped conduction and convection, and silvered walls later reflected radiant heat back inward. Dewar refused to patent the design, believing scientific tools should stay open. In 1904 German glassblowers Reinhold Burger and Albert Aschenbrenner added a protective metal case, patented the consumer version, and named it Thermos.

    Dewar sued and lost because he had never filed a patent, and Gustav Robert Paulin licensed the Thermos and mass produced it in places including Norwich, Connecticut. The flask's weak points are the neck and the stopper, and big versions need spacers that leak heat. Large Dewars hold liquid nitrogen at 77 Kelvin with slow boil off and no electricity, a nested double design holds liquid helium for MRI magnets, and NASA used vacuum flask technology in Saturn propellant tanks during Apollo.

    • The Arktek vaccine carrier keeps doses under 10 degrees Celsius for weeks using eight one liter blocks of ice.
    • Oil and gas crews shield wireline logging electronics inside Dewars in wells that reach 350 degrees Fahrenheit.
    • Glass flasks can implode from thermal shock, while sealed cryogenic tanks risk bursting because one liter of liquid nitrogen becomes nearly 700 liters of gas.
    • Industrial Dewars use pressure relief valves and corrugated expansion joints to survive.
    • In 1963 a US court declared thermos a generic term, stripping the company of exclusive rights to the name.

  • Internet Cafes: Seoul 1988, PC Bangs, Sweepstakes Raids, Tokyo Night Packs

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In March 1988 two professors in Seoul opened an electronic cafe with two 16-bit computers wired to online services over phone lines. In July 1991 Wayne Gregori put coin operated terminals into San Francisco coffeehouses as the SFnet network, a 32 line bulletin board with FidoNet email. Artist Ivan Pope coined cybercafe in early 1994 for an arts weekend at London's Institute of Contemporary Arts, and by late 1994 Cyberia in London, the Binary Cafe in Toronto, and the High Tech Cafe at the Dallas InfoMart were open.

    Where home connections lagged, cafes became utilities: shops in Mombasa paired computers with pharmacies and manicures, Indonesia had urban warnets and rural telecenters, and operators in India guided people through government forms. India fell from 180,000 cafes in 2008 to 50,000 in 2017, and the survivors live on printing and scanning. Where broadband spread, cafes turned into gaming halls, and governments pushed back with copyright suits, ID rules, and outright closures.

    • South Korea has over 20,000 PC bangs charging about 1,000 won an hour, making money on food and drinks.
    • Italy's 2005 anti-terror law required cafes to photocopy users' passports or IDs.
    • US sweepstakes parlors around 2010 sold internet time bundled with slot style entries until police raids and new laws.
    • Philippine com shops must keep 50 percent transparent storefronts, and some ordinances ban trash talk in multiplayer games.
    • In Japan, net cafe night packs gave rise to workers who live full time in booths because they cannot afford apartments.

  • Iced Coffee Worldwide: Algerian Mazagran, Flash Chill, and Aussie Cartons

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Around 1840 in Algeria, locals and French troops drank mazagran, coffee syrup cut with cold water, often called the original iced coffee. Italy later made frozen granita al caffe, and in 1920 the Joint Coffee Trade Publicity Committee pushed iced coffee in the United States to fix slumping summer sales. The chemistry sets three camps: cold brew steeps for 12 to 24 hours without heat and stays low in acid, double strength hot coffee over ice keeps the bright acids, and the Japanese flash chill drips hot coffee straight onto ice to lock in aromatics.

    Other countries made it dessert. Salento pours espresso over ice with almond milk, Germany's Eiskaffee adds vanilla ice cream and whipped cream, and Chile's cafe helado brings cinnamon, dulce de leche, and nuts, with casein in the dairy binding bitter tannins. Vietnam drips dark coffee through a phin onto shelf stable condensed milk, and Greece shakes instant Nescafe into the frappe, whose spray dried proteins hold a lasting foam. In South Australia, Farmers Union Iced Coffee outsells Coca-Cola.

    • Japan historically called cold brew Dutch coffee, a nod to trade with Dutch merchants.
    • Thailand's oliang is spiced with cardamom.
    • The frappe gained global attention after the 2004 Athens Olympics.
    • UCC Ueshima Coffee released canned liquid coffee in Japan in 1969.
    • Tim Hortons iced capps helped drive a 16 percent jump in Canadian iced coffee popularity between 2015 and 2016.

  • Friends, Born as Insomnia Cafe: The Cast's $1 Million Equal Pay Pact

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    In 1993 David Crane and Marta Kauffman, with Kevin Bright, had just seen CBS cancel Family Album when they pitched NBC a seven page treatment about six people in their twenties in Manhattan, under the working title Insomnia Cafe. Cameron Crowe has said Warner Bros. Television wanted to adapt his 1992 film Singles and used its premise when he declined, which the network and creators dispute. Casting went through about a thousand actors per role. Only Ross was written for a specific actor, David Schwimmer, while Courteney Cox talked her way from Rachel to Monica and Matt LeBlanc turned Joey from a sleazy womanizer into a sweet one.

    Jennifer Aniston and Matthew Perry were cast days before the pilot while still attached to Muddling Through and LAX 2194, and NBC bet those shows would fail. The cast then acted as a unit. Paid $22,500 each an episode in season one, they drifted apart to $20,000 to $40,000 in season two, and before season three, led by Schwimmer and Lisa Kudrow, demanded equal pay together. That reached $1 million an episode in seasons nine and ten, and a 2000 renegotiation won backend syndication points.

    • The famous Manhattan coffee shop was built on a soundstage in Burbank, California.
    • A University of Toronto study linked the show to the spread of so as an intensifier.
    • NBC paid Warner Bros. $10 million per episode for the final season.
    • The 2004 finale drew 52.5 million US viewers.
    • Around 2018, Friends accounted for about 4 percent of all Netflix viewing.

  • Four Loko: Ohio State Frat Basement, the FDA Caffeine Ban, and an eBay Rush

    Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode!

    Four Loko started with three recent Ohio State graduates, Chris Hunter, Jason Freeman, and Jeff Wright, who had mixed drinks in their Kappa Sigma house and resold Thai energy drinks bought at a local Asian market. In 2005 they formed Fusion Projects in Chicago and launched an energy beer in cherry and berry, named for four active ingredients: caffeine, taurine, guarana, and wormwood. Short on cash after a year, they dropped the wormwood, raised the alcohol, and sweetened the flavors, and by 2008 sales soared.

    When Anheuser-Busch and MillerCoors pulled caffeine from Tilt and Sparks under pressure from state attorneys general, Four Loko filled the gap. In 2010 nine students aged 17 to 19 connected to Central Washington University were hospitalized after a party in Roslyn, with blood alcohol levels up to 0.35. On November 17, 2010, the FDA sent warning letters declaring added caffeine in these malt drinks an unsafe food additive and gave the companies 15 days. Fusion Projects had already announced a reformulation the day before, and caffeine free cans reached shelves by late December.

    • Ramapo College banned the drink after 17 students and six visitors were hospitalized.
    • Oregon's liquor commission voted four to one for a ban, with 30 day license suspensions for sellers.
    • Before the deadline, full cans sold on eBay for up to five times retail.
    • The 23.5 ounce cans range from 6 to 14 percent alcohol depending on state rules.
    • The brand reached 21 countries, uses a vodka base in Europe, and released a strawberry daiquiri flavor called Jackpot in March 2026.
