Tasseography, the reading of tea leaves or coffee grounds, has a name built from French tasse, borrowed from Arabic tassa, plus Greek suffixes. Tea leaf reading began in China soon after tea itself, while coffee reading followed coffee out of Yemen through the Ottoman Empire and the Balkans, carried across borders in part by Romani oral tradition. In Europe older diviners read molten wax or lead dropped into cold water, and a Philippine healing practice called pagtatawas reads wax shapes to diagnose illness. In 16th century Ottoman palaces, women of the harem drank unfiltered Turkish coffee and turned the sludge into a tool for gossip and palace politics.

The Turkish method covers the cup with its saucer, flips it, and reads the grounds on a grid: bottom for the past, rim for the future, left for no, right for yes. A saucer that sticks is called the prophet's cup, and some readers say a cup sees only 40 days ahead. Tea leaves demanded a swirl and a Victorian dictionary of symbols, and potteries printed zodiac and playing card cups given away with bulk tea. The practice appears in Harry Potter, Coraline, The Waltons, and Abdel Halim Hafez's song Qareat al Fengan, and the episode links it to pareidolia and the 1921 Rorschach test.

• It is customary to ask a Romani elder's permission before giving a reading.
• A spade means success through hard work, a snake an enemy, and a mountain a hard journey.
• James Randi recorded Victorian rules such as a fat stem near the rim foretelling a stout visitor.
• Professor Trelawney sees the Grim in Harry's cup.
• Like an inkblot, the grounds give the brain chaos it rushes to turn into meaning.

The demitasse, French for half cup, holds about 60 to 90 milliliters, half of the roughly 120 milliliter tasse à café. Yet by the early 20th century the word had vanished in France, and in May 1946 scholar Clifford H. Bissell examined its disappearance in Modern Language Notes, published by Johns Hopkins University Press. The explanation is a semantic shift: once concentrated coffee became the everyday default in France, the small cup was no longer a half of anything, so people just ordered un café. Countries still drinking big mugs of drip coffee, like the United States, kept the word to describe the small European cup.

The Italian Espresso National Institute now sets the rules, calling for a white china cup of 50 to 100 milliliters. The episode argues this is sensory science rather than snobbery, since the white background heightens contrast with the crema and shapes how rich the coffee seems. Collectors went the other way, with Haviland pieces and an Imari pattern set at the Yale University Art Gallery. Elsewhere, the same problem of serving small, strong, hot coffee was solved differently, with the Turkish glass cup in a metal zarf and the Arabic finjan.

• The tiny volume acts as a limit on caffeine for a concentrated drink.
• The Italian rules specify white china, not glass or colored porcelain.
• A zarf's filigree cutouts cut contact with the hot glass and shed heat into the air.
• Clear glass lets drinkers see the coffee's color and texture.
• The small finjan requires constant refills, which paces hospitality and conversation.

Before a roaster ever sees it, a coffee bean has survived years of farming, fermentation, milling, and sorting. Coffee is grown in about 70 countries by roughly 100 million people, with Latin America producing almost 60% of Arabica and Vietnam leading Robusta. A new tree takes five years to give a useful harvest. Strip picking pulls ripe and unripe cherries together, and unripe fruit becomes Quakers, pale beans that taste like cardboard, so selective picking every eight to ten days matters. About 80% of coffee comes from holdings under two hectares, and pickers paid by the kilo earn as little as two to 21 cents per kilogram in Colombia.

The episode then compares processing: natural drying of whole cherries, washed coffee fermented 12 to 36 hours to strip mucilage, honey process that leaves mucilage on to sweeten the bean, carbonic maceration in CO2 tanks, and Indonesia's wet hulled giling basah. Wet processing turns 80% of the harvest into waste and can pollute rivers, prompting biogas and husk reuse. Dry mills hull, grade peaberries, blow off light beans in a catador, and fire air jets at defects, though Ethiopia and Tanzania still sort by hand. It ends with monsooned Malabar and decaf.

• Median seasonal earnings run about $20 a month in Ethiopia and $350 in Costa Rica.
• The US Department of Labor flags coffee from 17 countries for child or forced labor.
• Traditional washing uses 20 to 100 cubic meters of water per ton of green coffee.
• A 2021 health review found hand sorters, mostly women, face high dust related respiratory illness.
• The Swiss Water Process soaks beans in flavor saturated green coffee extract so only caffeine diffuses out.

For its first 12 years, the Starbucks Pumpkin Spice Latte contained no pumpkin at all. The flavor comes from pumpkin pie spice, a premixed tin of cinnamon, nutmeg, clove, and ginger that spice companies were selling by the 1930s, and small coffee shops were already adding fall spices in the 1990s. Tori Amos even told a 1995 Seattle crowd about her own pumpkin pie coffee. In early 2003 Starbucks tested four seasonal drinks, and chocolate and caramel beat pumpkin in consumer testing. Developer Peter Dukes fought to keep it, and his team worked in a lab decorated with fall leaves, eating bites of pumpkin pie followed by shots of espresso.

After test runs in Vancouver and Washington, D.C., in late 2003, the drink went national in 2004. In 2015 Starbucks trademarked PSL, dropped artificial colors, and added real pumpkin puree, which the Institute of Food Technologists said was imperceptible. Sales passed 200 million by 2013 and 424 million by 2019, and the drink is estimated at about $500 million a year as of 2025. Its limited season drives a spillover of pumpkin spice cough drops and pasta sauce and a halo effect that sends customers to Dunkin' and other rivals.

• Starbucks already had winter hits in the peppermint mocha and eggnog latte, and needed a drink for autumn.
• Dunkin' launched its version in 2007 and McDonald's by 2013.
• Starbucks foot traffic jumped 24.1% on its 2023 launch day, and 42 to 45% in some states.
• Dunkin' saw a 3% traffic rise in 2019 on the day Starbucks released the PSL.
• In September 2025 CEO Brian Niccol credited fall drinks for a record sales week at US company stores.

A true flat white is a double espresso of about 50 milliliters with roughly 130 milliliters of steamed milk and a thin, glossy layer of microfoam around five millimeters deep, served in a 175 to 200 milliliter cup. That makes it stronger than a latte and far less foamy than a cappuccino, and its smooth surface made it the drink of choice for latte art. Oddly, the name appears first in England: a character orders a flat white in the 1963 British thriller Danger by My Side, and the Oxford English Dictionary records a 1971 print use. The modern drink, though, took shape in Australia and New Zealand in the 1980s.

Australia's case includes a May 1983 Sydney review praising the flat white at Miller's Treat, Alan Preston putting it on the menu at Moors Espresso Bar in 1985 after Italian cane farmers in Queensland asked for white coffee flat, and a Canberra Parliament House cafeteria sign reading flat white only when seasonal milk would not froth. New Zealand points to Cafe DKD in Auckland and a botched cappuccino at Bar Bodega in Wellington in 1989. Expats carried the drink to London by 2005, Starbucks trialed it in the UK in 2010 and launched it in North America in 2015, and economist Douglas McWilliams named the flat white economy.

• A 1984 Sydney article told readers a caffe latte was basically their local flat white.
• Cafe DKD's founders said they learned the name from a friend who had worked in Sydney.
• Hugh Jackman co-owned a New York cafe to help push the Australian drink to Americans.
• In 2024 one in three UK coffee drinkers named the flat white as their main order.
• Pret A Manger sold 8 million flat whites in a year, close to its 9 million cappuccinos.

The little green frog seal on coffee, tea, and bananas belongs to the Rainforest Alliance, founded in 1987 by Daniel Katz. As of 2023 it covered more than 70 countries, over seven and a half million farmers and workers, and more than 5.7 million hectares. After merging with the Dutch program UTZ in 2018, it rolled out the 2020 Sustainable Agriculture Standard with two tiers: core requirements such as ecosystem protection, a ban on transgenic crops, protective gear, and an assess and address system for child and forced labor, plus improvement requirements tracked through smart meters that let each farm set local targets.

Unlike Fairtrade, the Rainforest Alliance has never guaranteed a minimum price, a gap critics such as sociologist Daniel Jaffee stress by pointing to the early 2000s coffee crash, when prices fell from about $1.20 to roughly 50 cents a pound. It added a mandatory sustainability differential, including $70 per metric ton of cocoa from mid 2022. Labeling rules went from 30% certified content in the mid 2000s to 90% or mass balance today. Then came the 2020 revolt, when banana growers in Ecuador, Costa Rica, Colombia, and Guatemala said they paid for compliance while European supermarkets pushed prices down.

• Herbs need only 50% certified content and palm oil 30%, with the percentage printed on the pack.
• Forestry and tourism certification went to Preferred by Nature in 2018.
• A 2024 report sets a goal of 100 million farmers in regenerative practices by 2030.
• A 2014 WASH lawsuit over Chiquita suppliers in Guatemala was dismissed in 2016, and a suit also naming Hershey was dismissed in 2023.
• The banana growers said only 2% of their demands were heard in drafting the new standard.

Order a white coffee and what arrives depends on where you are standing. In Britain it simply means black coffee with a cold or room temperature whitener, which is what separates it from a café au lait made with steamed milk. In New England and New York the same drink is light or regular coffee. In American specialty cafes, white coffee means beans pulled from the roaster at a yellow roast, brewed as espresso into a thin, nutty, acidic, low bitterness shot, often discarding the first pour. The beans stay dense because they never expand like popcorn, which is why sellers suggest buying them pre ground.

The episode tests the claim that yellow roast is extra caffeinated: caffeine sublimes around 352 degrees Fahrenheit, yet it survives dark roasts largely intact, so the content by weight is essentially the same. In Ipoh, Malaysia, white coffee means imported beans roasted in margarine and served with condensed milk, often sold as 3 in 1 packets. Johor uses Liberica without margarine, Indonesia's kopi putih uses a short, low heat roast, and Singapore's kopitiam filters coffee through a cloth sock. Yemen brews white coffee from the cherry husk, and in the Levant kahwa bida contains no coffee at all.

• Malaysian white coffee does not come from a special plant, despite what many tourists believe.
• Roasting in margarine caramelizes fats and sugars on the bean's surface.
• Kopitiam joins the Malay word for coffee with the Hokkien word for shop.
• The cloth sock lets heavy coffee oils through, giving a syrupy body that stands up to condensed milk.
• Kahwa bida is hot water with orange blossom or rose water, served after meals in Syria and Lebanon.

In the working class cafes of Naples, a customer having a lucky day would pay for two coffees, drink one, and leave the second suspended for a stranger who could not afford it. The caffè sospeso was built on anonymity: the giver and receiver never meet, the barista acts as a neutral go-between, and the person asking keeps their dignity. The tradition faded during Italy's postwar boom of the 1950s and 1960s, and a reporter searching Naples in 2008 found no sign of it for at least 15 years. That same year philosopher Luciano De Crescenzo published a book titled Il caffè sospeso, and SSC Napoli chairman Aurelio De Laurentiis made a habit of buying ten sospesi after every win.

The revival arrived just as the 2008 financial crisis and the eurozone debt crisis hit. By 2011 Italian arts festivals had formed a Suspended Coffee Network, and Naples declared a suspended coffee day timed to Human Rights Day in December. In March 2013 Irish plumber John Sweeney started a Suspended Coffees Facebook page credited with inspiring more than 15 million suspended coffees in 34 countries. Starbucks UK adapted it as a matched cash donation to the charity Oasis. During the 2020 COVID lockdowns, Italians extended the idea to groceries, bread, and hot meals.

• A Dutch Christmas campaign and the platform OneCafe.org helped formalize the practice.
• In July 2013 an anonymous customer at an Edmonton Tim Hortons paid for 500 large coffees.
• That act set off more than 10,000 donated cups across 30 Edmonton locations.
• In September 2021 a donor in Istanbul paid for 501 Turkish coffees to top the Canadian record.
• The Istanbul gift was reported as the largest single suspended coffee donation in a hundred years.

Coffea liberica makes up less than 1.5% of commercially grown coffee, yet it once sold for up to five times the price of other coffee. The trees reach 20 meters, so harvesters use ladders, and the asymmetrical, hooked beans reach about 12 millimeters, with 100 beans weighing 23.2 to 25.7 grams in a Selangor, Malaysia study. Cuppers compare it to jackfruit. A light roast keeps the fruit, a medium roast brings chocolate and caramel, and a dark roast turns it bitter and astringent. Its caffeine is modest: in one Malaysian analysis Liberica came in at 1.23 grams per 100 grams, below Arabica at 1.61 and Robusta at 2.26.

Spanish friars brought it to Lipa, Batangas, in the 1740s, where it became kapeng barako, a name traced to wild boar. Exports from the Philippines and Liberia boomed, and the 1876 Centennial Exposition in Philadelphia lifted American demand. Coffee leaf rust eventually overwhelmed even Liberica, and growers replanted with easier Arabica and Robusta. It survived in Java, West Kalimantan, and Johor, where it tolerates acidic, waterlogged peat soils. That makes it a transitional crop in place of oil palm, which needs deep drainage that releases carbon and makes the land sink. Genetic studies in 2025 and 2026 then rewrote what Liberica even is.

• Tropical peatlands can reach a pH of 3.5 to 4, which kills Arabica and Robusta roots.
• Liberica needs only shallow drainage, not true paludiculture, but far less than oil palm.
• A 2006 consensus had merged excelsa and other large leaf coffees into Liberica.
• The 2025 study split them back into C. liberica, C. dewevrei, and a third West Central African species.
• A 2026 study found much Southeast Asian Liberica is a natural hybrid and proposed the name Coffea x libex.

George Constant Lewis Washington was born in May 1871 in Kortrijk, Belgium, to a Belgian mother and an English father, which made him a British subject until he became an American citizen in 1918. After a chemistry degree at the University of Bonn and marriage to Angeline in 1895, he arrived in New York around 1896 and started the George Washington Lighting Company in Jersey City, making kerosene gas mantles just as electric light took over. Around 1906 he went to Guatemala to try cattle ranching, where he supposedly noticed dried coffee powder on the spout of a silver pot. Back in New York he launched Red E Coffee in 1909 and incorporated the G. Washington Coffee Refining Company in Brooklyn in 1910.

He was not the first: David Strang in New Zealand and Satoru Kato had soluble coffee earlier, and his own Guatemalan physician, Federico Lehnhoff Wyld, developed a process at the same time. Washington's edge was mass production. His ads claimed the coffee aided digestion and did not cause wakefulness, and his company later sponsored The Adventures of Sherlock Holmes on NBC. When the United States entered World War I, the War Department took his entire output, and soldiers called it a Cup of George. The fortune bought a Park Slope mansion, a Long Island estate full of exotic animals, and a federal tax fight.

• Military demand at the war's peak reached six times the national civilian supply.
• His 40 acre Washington Lodge had 18 bedrooms and the largest concrete pool in New York State.
• Brooklyn political bosses entered him in the 1920 South Dakota presidential primary, though he was ineligible.
• He lost a 1927 tax evasion case 2 to 1 over royalties routed to family members.
• He sold the company in 1943, the coffee was discontinued by 1961, and G. Washington's seasoning and broth is still sold.
