Our appellation has such a strong personality that it has given its name to our region: THE GRAVES.
These graves, or gravelly soil, consist of layers of alluvial, sandy, and stony soil deposited on a limestone subsoil by tumultuous rivers and glaciers during the Quaternary Period. This soil was later affected by erosion.
At Smith Haut Lafitte, we have a rare example of a croupe, or rise of Günze gravel.
This is thick and ochre-coloured, reflecting its high iron oxide content. This soil is perfect for growing wine grapes because it is well-drained, meagre, warm on the surface, and cool as well as humid deep down (thanks to clay and limestone) This means that the vines grow slowly and have naturally low yields, and that the grapes ripen slowly and fully (the wet soil deep down regulates water supply and makes for good, even ripening).
In parts of the vineyard where there is a higher proportion of clay and the vineyards are north facing, we planted white wine varieties to maintain their aromatic potential during hot, dry weather. We planted Cabernet Sauvignon on dryer, more gravelly soil, because this variety needs more encouraging to ripen.
We have thus adapted the optimum grape variety to each plot to make the most of our fine Günz gravel terroirs.
