The Merlot grape is a close cousin to Cabernet Sauvignon in many respects. It is lower in tannins and makes wines that mature faster and are softer in texture. Merlot is often blended with Cabernet Sauvignon in order to soften the blend.

Merlot is able to mature in regions that are cooler than those required for Cabernet Sauvignon. Merlot is more susceptible to fungus and mould diseases and therefore a bit harder to grow. Merlot varies widely in quality around the world depending on location and producer. This variety was first known for its success in the Saint Emilion and Pomerol areas of Bordeaux. Chateau Petrus is the stellar example of fine Merlot. Merlot usually has ripe berry components in the bouquet. It's wines tend to be soft, fruity and smooth in texture. Select Merlots can have long aging potential but most are ready to consume in 4 to 8 years. Merlot is enjoying a surge in popularity and additional acreage is being planted in many major producing regions. It came to California in the mid-1860s and has become one of the most popular wines since its surge in popularity in the 1990s.
