What did the Romans actually have in their cups? Joel Butler, one of the first two US-resident Masters of Wine (a title he earned in 1990), joins host Noah Tetzner to explore the wine culture that spread across an empire and still shapes the bottle on your table today.

Joel is co-author, with biblical historian Randall Heskett, of Divine Vintage: Following the Wine Trail from Genesis to the Modern Age, winner of the 2012 Gourmand International UK Best Wine Book Award. He also wrote the entry on the Roman Empire for the Sage Encyclopedia of Alcohol, and has spent more than five decades in wine as a buyer, importer, educator, winemaker, and judge. He now writes the Substack journal The WineKnowLog and serves as a Contributing Editor for the International Wine Review.

Joel traces how the vine moved from the Near East through Greece and the Etruscans before Rome turned it into an empire-wide industry, and why Roman wine was routinely cut with herbs, spices, pitch, and even seawater. He explains why Falernian became Rome’s most legendary wine and takes on Pliny the Elder’s claim that it could catch fire. He also follows the genetic threads connecting Roman-era grapes to today’s Aglianico, Syrah, and Dureza, before confessing the 1964 Barolo that first caught his attention at his parents’ dinner table, and sharing advice for anyone chasing the Master of Wine title today.

In this episode:

• What did wine actually taste like in ancient Rome?
• Why did Falernian stay famous for centuries?
• Did the Romans rank their vineyards and vintages like we do?
• How did wine become one of the empire’s biggest industries?
• What does grape DNA reveal about Rome’s wine legacy?

Where does your wine really come from? Swiss botanist and grape geneticist Dr. José Vouillamoz, co-author of the James Beard Award–winning Wine Grapes: A Complete Guide to 1,368 Vine Varieties, joins host Noah Tetzner to explain how DNA profiling reveals the hidden family trees behind the grapes in your glass.

José explains in plain English how scientists identify a grape's parents, including the discovery that Cabernet Sauvignon is the offspring of Cabernet Franc and Sauvignon Blanc. He shares why every traditional grape variety began as a chance seedling in someone's vineyard, how his research with the late archaeologist Patrick McGovern pointed to southeastern Anatolia as a cradle of grapevine domestication, and why tiny Switzerland grows more than 300 grape varieties. He also confesses to the first wine that ever caught his attention, a 1972 Malvoisie he and his friends swiped from a cellar at age 15, and explains why he has no patience for "grape patriotism."

In this episode:

- How does grape DNA profiling work?

- Who are Cabernet Sauvignon's parents?

- Why is every grape variety "man-made"?

- Where was the grapevine first domesticated?

- Why does Switzerland have so many native grape varieties?

José's new English edition of Swiss Grapes and his short book Grape Varieties: Their Future, published by the International Wine & Food Society, are both due out November 1, 2026.

In June 1940, France fell to Nazi Germany, and the occupiers quickly set their sights on one of the country's greatest treasures: its wine. Award-winning journalists Don and Petie Kladstrup, authors of Wine and War: The French, the Nazis, and the Battle for France's Greatest Treasure, join host Noah Tetzner to tell the story of the winemakers who hid, smuggled, and sabotaged their wine to keep it out of German hands.

Don and Petie explain who the weinführers were: German wine merchants the Reich sent into France to buy up its best bottles, many of whom ended up protecting the very trade they were sent to exploit. They share stories of false walls, wine siphoned from Germany-bound trains and replaced with water, a housekeeper who scattered rat droppings to stop German officers from turning a Bordeaux château into a brothel, and Alsace winemakers who deliberately misdirected shipments. They also discuss Bordeaux merchant Louis Eschenauer, convicted of economic collaboration after the war; what became of the wine the Germans took, including the cache found at Hitler's Eagle's Nest; and the 1947 Vouvray from Gaston Huet that first showed them wine could be more than a drink.

In this episode:

- What happened to French wine when Germany occupied France in 1940?

- Who were the weinführers, and why did some French winemakers say they saved French wine?

- How did French winemakers hide and sabotage their wine?

- What happened to the wine the Nazis took?

- Why does war keep shaping the story of French wine, especially in Champagne?

What is terroir, and is it really just soil and climate? Anthropologist Marion Demossier, Professor of French and European Studies at the University of Southampton and author of Burgundy: The Global Story of Terroir, joins host Noah Tetzner to explore Burgundy's wine culture and how the idea of terroir traveled around the world.

Born in Beaune, in the heart of Burgundy's wine country, and raised in a family where her grandfather was a wine merchant, Marion has spent more than three decades studying the region's wine growers. She explains why Burgundy's famous landscape is as much a product of labor, land ownership, and law as of geology, and what she saw from inside the room when she was brought in to write an anthropological report for Burgundy's UNESCO World Heritage bid. She traces how terroir was translated in China, Japan, South Korea, and New Zealand, shares memories of legendary cellar tastings in Beaune and Champagne interviews that began with a glass at 10 a.m., and explains why climate change may force the wine world to rethink its traditions.

In this episode:

- What does terroir mean, and why has the word never been translated?

- Why did Burgundy become synonymous with wine?

- Is Burgundy's landscape naturally exceptional, or shaped by people and law?

- How did the idea of terroir travel to Asia and New Zealand?

- How is climate change challenging Burgundy's traditions?

Why did France become the center of the wine world? Wine historian Rod Phillips, Professor of History at Carleton University and author of French Wine: A History, Alcohol: A History, and 9000 Years of Wine, joins host Noah Tetzner to explore how wine shaped, and was shaped by, centuries of history.

Rod shares how he bought his first case of wine at 15 in New Zealand, became a restaurant sommelier at 17, and found two bottles of 1950 Bordeaux selling for the price of a hamburger. From there, we travel from medieval Bordeaux and the English market that made claret, sherry, port, and Champagne famous, to the French Revolution, when a Burgundy man was tried for treason and executed in 1793 for serving bad wine to soldiers. Rod also takes apart the popular myth that people drank wine because water was unsafe, explains why the wine Hemingway drank in 1920s Paris was likely far lower in alcohol than today's, and makes the case for Canadian wine, from the Okanagan Valley and Niagara to Prince Edward County.

In this episode:

- Why did France become the reference point for the wine world?

- Did people in the past drink wine because water was unsafe?

- How strong was wine a century ago?

- How did the French Revolution change French wine?

- What should you know about Canadian wine beyond icewine?
