Bordeaux; most people have heard of this French wine region, which is one of the most famous Old World wine regions, but many people don’t understand it. To begin with, Bordeaux is divided into two sections, referred to as the Left Bank and the Right Bank. The banks refer to the left (west)and right (east) bank of the Gironde Estuary and Garonne River.

The Left and Right banks have significantly different terroirs. A terroir is the natural environment in which a particular wine is produced, including factors such as the soil, topography, and climate.  

The soil is rockier on the Left Bank. It is packed with gravel and deep deposits of limestone which serves to provide more character and potential quality in the wine. This is why Left Bank wines are considered prime candidates for aging, while Right Bank wines are generally thought to be smoother and more drinkable at the time they are released for sale.

This is not to suggest that Right Bank wines are simple and boring. With limestone closer to the surface and less gravel for the vine roots to contend with, the wines of the Right Bank don’t lack character; it’s just that they possess a different kind of character.

When it comes to the grape varietals grown, because of the differences in the terroir between the Left and Right Bank, each supports its own type of grape. As a result, this is often the best way to distinguish between a Left and Right Bank Bordeaux, as the label will not often tell you. Left Bank wines are mostly Cabernet Sauvignon with a smaller portion of Merlot. The Right Bank wines are dominated by Merlot balanced by a smaller proportion of Cabernet.

The Cabernet dominated Left Bank wines tend to be higher in tannin, thus the reason why they age well. Aging the wine helps to mellow out the tannins and integrate the flavors of the wine. Merlot-based Right Bank wines are generally smoother, with softer fruit flavours as tannins are not as dominating.

The last comparison is between the wineries or chateaux themselves. These are the castle-like structures that appear on many of the Bordeaux wine labels.  Generally, the Left Bank chateaux have larger vineyards than those of the Right Bank. Left Bank vineyards are on average 5o to 80 hectares in size versus those of the Right Bank, which only have a maximum of about 30 hectares. However, this is only a fun-fact as vineyard size really has no impact on the quality or character of the wine. Arguably the most renown chateaux include Chateau Margaux, Lafite, and Mouton Rothschild on the Left Bank and Petrus and Cheval Blanc from the Right Bank.

So, which wines are better?  Neither. If you are looking for a wine to enjoy with dinner tonight, a Right Bank wine is probably the better choice, whereas if you are looking for a wine to age and appreciate in the future, you will find that a Left Bank wine will improve with age and provide a delightfully satisfying experience when it is uncorked in a few years’ time.
