FIELD NOTE 01
From the Atlantic side inland
On the river mouth side of Bordeaux and the Loire, the influence of the Atlantic Ocean is a key factor. As you move inland, conditions change, and within the Loire itself, you encounter regions with different grape varieties. Rather than just arranging climates by latitude, it's better to consider both distance from the sea and the position of mountains.
Alsace's location on the eastern side of the Vosges Mountains results in a low-rainfall environment. Saying only that it is in the northeast of the country does not fully explain this.
FIELD NOTE 02
Even on the Mediterranean coast, elevation varies.
In southern Languedoc and Provence, there are coastal plains and inland hills. Corsica also has mountains, so you cannot generalize the south as uniformly hot lowlands.
Vineyard elevation and aspect are items to compare within the same region. Geological names indicate the site's origins, but do not by themselves dictate the wine’s aroma and flavor.
FIELD NOTE 03
Separate administrative boundaries and production areas.
Regions such as Bordeaux, the Loire, and the Rhône are grouped together as coherent wine regions for study. These do not necessarily match administrative divisions or the boundaries of a single AOP.
The maps on this site indicate representative locations for 14 regions. When moving from regions to individual appellations, the official zoning maps and regulations are used to narrow down the boundaries.
Check, in addition to latitude, the distance from the sea, mountains, altitude, and slope orientation. The low rainfall in Alsace and the inland hills in the south are examples indicating this need.
PAUSE & REFLECT
Check your understanding.
Does simply splitting France into North = cool, South = warm suffice for explaining vineyard conditions?
