Wine and Geology Tours

October 6-13, 2019

8 days, 7 nights

Discover the essence of Burgundy: Its terroir, the deep underpinnings of its geology, the wines and the cuisine, as we tour Burgundy from North to South.


Starting in northernmost Burgundy, in Chablis, we will learn why the Premier and Grand Cru vineyards and their Kimmeridgian limestone geologic history make the wines of Burgundy what they are. From the wine capital of Burgundy, Beaune, we’ll explore the world-renowned vineyards of the Côte de Beaune, the Côte de Nuits while enjoying the fabulous cuisine of the region.


We will check out the unoaked chards of little-known villages in the Mâconnais, the off-the-beaten-path wines of Givry, Mercurey, Rully, Bouzeron in the Chalonnaise into the famous Côte d’Or.


Taking us through the granite hills of Beaujolais to the stunning limestone formations of Solutré and Vergisson, our journey will end in the food-and-wine-capital, Lyon.

A professional driver and comfortable bus will transport us from start to finish so there is no need to worry about driving once you get there.

Burgundy North

to South

8 days, 7 nights

Join us for a week in exploring the wines and geology from Côte Rôtie to the Sea. From the French food and wine capital Lyon we head south through 400 million year old metamorphic terrain of the steep northern Rhône vineyards of Côte Rôtie - the “roasted slope”.


From there we continue down river into Hermitage, Gigondas, Châteauneuf-du-Pape, the Côtes du Rhône, Ventoux and Luberon to Aix-en-Provence, and ending along the coast at Cassis and Bandol. We will make a picnic stop at Mont Sainte-Victoire, the mountain made famous by Cezanne and is itself a spectacular example of how limestone strata become folded and contorted where continents collide.


Throughout this excursion the geology is as varied and complex as the wines are themselves. We will visit great vineyards and meet their winemakers all the while learning what makes each of these places special and unique.

Thirteen wine enthusiasts joined us in Demystifying Sonoma's AVAs as we investigated the complex and overlapping array of the Sonoma AVAs.


We visited select wineries that are true to their respective terroir. The French would say they are “correct”.


We discussed how the topography of the region reflects effects of tectonic forces — the San Andreas, Rodgers Creek and related faults, and the east-west compressional forces that have folded the terrain into discrete valleys, ridges, alluvial fans and river corridors.


We spent the weekend visiting vintners at their wineries, to learn about their soils and wine-growing practices, and how these affect their wines.


We learned about their vinification processes and of course, tasted their wines.


Oh yes, a locally-sourced wine dinner was prepared by a well-known Sonoma chef and topped off our wine country explorations.
