Why does Bordeaux label their wine with regions and not the grapes?
The tradition across France, as well as all of Europe, is to label wine according to where it was made. Bordeaux uses a blend of five different grapes and the amount of each grape in any bottle will vary widely across all of Bordeaux and from year to year. Therefore, it is more useful to know which region of Bordeaux it came from as each region (known as an appellation) has a distinct style year in and year out.
