The notion of second wine refers to the second wines of Bordeaux chateaux. It means wines from the same terroirs, having benefited from the same know-how but which are judged, at the time of assembly, not qualitative enough to enter the composition of the first wines. They can come from young plots, barrels where breeding will not have achieved excellence.
The marketing of second wines became widespread in the early 1980s in the face of soaring prices for Grand Crus. A solution allowing chateaux to ensure a high-end positioning for their first wines and consumers to access renowned wines.
In great vintages, we even talk about super seconds. Second wines are as good as the first, but at prices two to three times lower.
