Merlot has a reputation for producing smooth, velvety wines that vary depending upon the climate and soil type. Warm conditions on clay soils often produce soft, fruit forward styles. Cool, higher elevation sites produce wine with a slightly more austere structure. It still reigns as one of the world's most noble varieties forming the majority of the blend in Bordeaux’s right bank vineyards of Pomerol and Saint-Emilion. It is now prevalent across the world, achieving particular success in South America, California, and Washington. In central Italy, Merlot is either bottled as a varietal or blended with Sangiovese and Cabernet Sauvignon to form Indicazione Geografica Tipica's (IGT), known as Super Tuscans.
