Geology of Burgundy

Rocks, landscape, and terroir are the heritage of a rich past deeply etched in the soil. Approximately 300 million years ago, Burgundy was a mountainous country located near the equator with a hot and humid climate. During the Secondary Age (-245 to -65 million), the continent moved and the sea advanced. During the Jurassic Period (-205 to -135 million) the sea level fluctuated, tectonic plates moved, the landscape of oolitic dunes, which would in time give calcareous scarps, separated the vast central lagoon of the sea and its various currents and the clayey depths, the result of minerals altering, would eventually form marl.

In total, close to 2000 metres of land piled up like a gigantic millefeuille in which, under the weight of sediment and as a result of the plates stretching, the relief sculpted itself. During the Tertiary Age, approximately 60 million years ago, pressure from the African plate pushed Burgundy out of the water. The weather was still hot and humid. Again pressure from both the African ad European plates caused Burgundy to bend and fracture leaving great fault lines to this day. Erosion then took over; rivers forged themselves and caves and underground tunnels formed in the limestone.

During the Quaternary Age (approximately 2 million years ago) a bitter cold settled in. Glaciers succeeded in shattering rocks, eroding and washing away debris. For the last 15,000 years the climate has been much milder and we no longer speak of alternating periods of hot and cold. Man settled here definitively approximately 6,000 to 7,000 years ago (during the Neolithic period).

 

 

In terms of climate, Burgundy is situated at the edge of both continental and maritime influences, thus the western winds, which bring rain, often lose any moisture when they reach the hills. As for the cold dry north winds, they ensure a good sanitary state of the vines.
The wine region of Burgundy, which extends over 250 km long from Chablis in the north to Mâcon in the south, runs along side the eastern slope of the Massif Central and the burgundian plateau for almost 140 km.

The vineyards and villages follow the right axis of the hill in a straight line. It is the lower third of the slope, where the most moderate incline has retained the "terre rouge" scattered with lava, where the vineyards are situated. This narrow strip is rich in soils whose diversity is due to the discontinuity of geographical layers.
