There are few regions in the world with stricter regulations in regards to wine production and grape varietals than those found in Bordeaux, France. Here, in the home of the world's finest wines, the type and quality of grapes used is of utmost importance, and the legendary wineries which work on the banks of the Gironde river have mastered the careful art of juice blending to find the perfect balance for their produce. Whilst there are six 'official' Bordeaux grapes, the two key varietals for almost every fine Bordeaux wine are Cabernet Sauvignon and Merlot, and with good reason. Whilst Cabernet Sauvignon grapes are renowned for their acidity and astringency, strong fruit and spice flavors and full body, Merlot grapes are notably rounded, soft, fleshy and lighter on tannin. The combination of these two varietals, along with a small percentage of (commonly) Petit Verdot or Cabernet Franc, is the perfect balancing act – the two grape varietals cancel out each others weaker points, and accentuate all that is good about the other. The beautiful sub-region of Saint Emilion in France's legendary Bordeaux region is regarded as the home of many of the world's finest red wines. The blending techniques employed in Saint Emilion have been passed down for generations, and aim to express the very finest flavors of the grape varietals used, most commonly Cabernet Sauvignon, Merlot and Cabernet Franc. The climatic conditions in Saint Emilion are perfect for growing many of the Bordeaux grapes, and high yields of exceptional quality are commonplace. Fed by the mighty Gironde river and benefiting from superb clay and gravel based soils, Saint Emilion produces millions of bottles of high quality blended and unblended red wines each year, and continues to be a firm favorite of wine experts and the general public alike.
