Confusion Corner: Cadillac

January 21, 2025 Leave a comment

It’s a place! It’s a person! It’s a car! It’s two separate AOCs! Cadillac—a word with many meanings—is long overdue for an untangle here in the Confusion Corner.

Since this is a wine blog, we’ll start with the town and the wines of Cadillac. But hang on for a great story about a character who crowned himself the Sire of Cadillac, and how this relates to the automotive legend known as the Cadillac Sedan.

The town—Cadillac, France: Cadillac—population: 2,800— is a small town (commune) in Nouvelle-Aquitaine, France. The town has history: it was established in 1280 by Jean I de Grailly—a senior official of the Duchy of Gascony—in order to provide river access for the Château de Benauge. These days, the small town serves as an excellent home base or stop-over for a wine tour of Entre-Deux-Mers, the Médoc, and Graves; and you can visit the imposing Castle of the Dukes of Eperson (Château des ducs d’Épernon/Château de Cadillac) built in the 1500s. Along the way, you can visit the Château de Benauge (about 6 km/4 miles to the northeast).

The wines—the Cadillac AOC: The Cadillac AOC is located just to the east of some of Bordeaux’s most famous sweet wine-producing regions, including Sauternes, Barsac, and Cérons. The Cadillac AOC hugs the east bank of the Garonne River and is home to dozens of lakes, rivers, and streams—including the Estey de Rouquey, the Lac de Baurech, and the Ruisseau de l’Euille. All this flowing water creates a recurring layer of mists and fog— which settles into the nooks and crannies of the lowest-lying vineyards—and allows for the formation of botrytis cinerea on the vines. This in turn allows for the production of luscious, flavorful, sweet white wines—and, like many appellations that surround it, the Cadillac AOC is approved for sweet white wines only. The main grape variety of the Cadillac AOC is Sémillon; Sauvignon Blanc, Muscadelle, and Sauvignon Gris are allowed as well. The wines of the Cadillac AOC must contain a minimum of 51 g/L residual sugar; grapes may be affected by botrytis and/or air-dried after harvest (a process known as passerillage).

The wines—the Cadillac-Côtes de Bordeaux AOC: The entire area of the Cadillac AOC (as well as a small parcel extending from its northern edge) is included in another appellation, the Côtes de Bordeaux AOC. Cadillac is a sub-appellation of the larger Côtes de Bordeaux AOC, which encompasses four discontiguous plots of land (and five named sub-appellations) located to the east of the Garonne River and the Gironde Estuary. As if that weren’t confusing enough, the Cadillac-Côtes de Bordeaux AOC—is approved only for red wine. The allowed grape varieties mirror those used throughout most of Bordeaux and include Cabernet Sauvignon, Merlot, Malbec, Carmenère, and Petit Verdot. (For serious wine students: the five sub-appellations of the Côtes de Bordeaux AOC are: Cadillac, Castillon, Sainte Foy, Francs, and Blaye.)

The man and the car: In 1683, a fascinating character named Antoine Laumet left his home in France and arrived at Port Royal—the then-capital of Acadia/New France (and modern-day Nova Scotia, Canada). Upon his arrival in North America, he declared himself Antoine de la Mothe, écuyer, sieur de Cadillac and embarked upon several decades worth of escapades, serving at various times as an explorer, cartographer, merchant, and officer of the French Navy. In 1701, he helped to establish Fort Pontchartrain du Détroit on the north bank of the Detroit River. The fort became part of the modern city of Detroit, Michigan.

For many generations, Laumet—under his assumed nickname, Cadillac— was hailed as a hero (or at least, a founding father of sorts). A French High School in Ontario was named after him, the Cadillac Line on the Montreal Metro bears his name, as does Cadillac Mountain in Maine. Cadillac—the famous American Car Brand, headquartered in Detroit—was indeed named after him, and the original crest of the Cadillac Brand was modeled after his self-created amorial bearings (“family” coat of arms).

Postscript—and now we know: It has come to light that Antoine Laumet/Mssr. Cadillac was not quite the hero he was once believed to be. It has been revealed that he frequently abused his power; was abrasive (to say the least); traded heavily in fur, alcohol, and other products to the detriment of the First Nations; and was most likely involved in some of the earliest instances of the slave trade in North America. Le sigh.

Five Fast Facts about the Bay of Biscay

January 8, 2025 1 Comment

Biarritz (France)

If you are a wine student who has studied Bordeaux, you’ve heard of the Bay of Biscay. If you have dreamed of traveling to the resort town of Biarritz, you’ve heard of the Bay of Biscay.  If you are a sailor who likes a challenge, you’ve heard of the Bay of Biscay. If you are interested in learning more, read on for five fast facts about the Bay of Biscay!

#1: The name and the place: The Bay of Biscay is a portion of the Atlantic Ocean located off the west coast of France and the northern coast of Spain. It stretches from Point Penmarch (a small peninsula in Brittany’s Finistère department) in the north to Cape Ortegal (a headland on the shores of A Coruña, Galicia) in the south. It is named for the province of Biscay—a sub-region of Basque Autonomous Community of Spain (Comunidad Autónoma del País Vasco).

If you sailed from Point Penmarch to Cape Ortegal (you might want to consult item #5 before doing so), you would cover 360 miles/580km; if you drove the coast, you would cover 914 miles/1,475 km and pass through the cities of Nantes, Bordeaux, Bayonne, San Sebastian, and Bilbao.

#2: It’s a bay…it’s a gulf…it’s a sea: The term Bay of Biscay is used mostly by English Speakers. In France, this area is known as the Golfe de Gascogne (Gulf of Gascony), and many Spanish speakers know it as the Golfo de Vizcaya (Gulf of Biscay/Vizcaya). In Spain, the waters just off the coast of Northern Spain (stretching east to the French city of Bayonne) are known as the Mar Cantábrico (Cantabrian Sea).

  • For the geo-curious: Terms such as bay, gulf, and sea are loosely defined. However, according to the National Geographic Education Resource Library:
    • A bay is any body of water partially surrounded by land.
    • A gulf is a portion of the ocean that penetrates land. (As such, the terms bay and gulf are largely interchangeable.) While there are some exceptions (such as the Bay of Bengal), in common use a gulf is larger than a bay.
    • Sea is a broad term that may be applied to more than 50 different types of water formations; this term is typically reserved for bodies of salt water.

#3: The Rennell Current: Several ocean currents flow through the Bay of Biscay, all of which are considered branches of the Gulf Stream. The Gulf Stream—named for its source (the Gulf of Mexico, at 20°N)—carries warm water northward and eventually reaches the northern coast of Europe. The portion of the current flowing closest to the coast in the Bay of Biscay is known as the Rennell Current, named for James Rennell (1742–18300, a British geographer and oceanographer who studied and mapped many ocean currents. It is estimated that the Rennell Current can have a warming effect of up to 4°(F) on the areas along the coast of France.

#4: The triangle of fog: Fog can show up at any time and just about any place on the Bay of Biscay, but it is an almost daily occurrence during late spring and all through summer, particularly in the southwest portion of the bay.  This “triangle of fog” typically forms over the deepest water in the bay and can extend inland along the northern coast of Spain (Galicia–Asturias–Cantabria—Basque Country) for several miles.On th

On the coast in Deba (Basque Country, Spain)

#5: The shelf and the shallow: The Bay of Biscay has a long history of shipwrecks, rough water, and tumultuous storms. During the winter months, areas of low pressure (unstable air masses/depressions) track into the bay via the Gulf Stream and are easily energized into fierce thunderstorms, much to the dismay of anyone caught on the open water.  At times, these thunderstorms are met with winds from the east and this clash of wind and rain can cause the water to churn “like a washing machine.” In addition, the continental shelf extends over a large portion of the bay, resulting in shallow water and rough seas that can occur during all types of weather.  Click here to see a detailed map of the continental shelf in the Bay of Biscay. 

Here’s to the Bay of Biscay! The next time you raise a glass of Muscadet, Cognac, Txakolina, Sidra de Asturias, or Bordeaux…remember to pay homage to the influence of the Bay of Biscay…whether it be storms or fog or ships that made it through.
