Château Trotanoy is a Bordeaux wine estate in the Pomerol appellation, regarded as one of the great wines of the right bank. The Merlot-dominant wine is known for its decadent, rich style, and its prices are among the highest in Bordeaux. In the 18th Century, the estate was known as Trop Ennuie, or "Too Annoying", due to the poor, hard-to-work nature of the soils here. These are made up of clay with deposits of gravel and iron, and are now considered as very good soils for viticulture. Château Trotanoy is located on the western side of the Pomerol plateau, not far from Pétrus and Lafleur, and covers 7 hectares (18 acres). Around 90 percent of this is planted to Merlot, with Cabernet Franc accounting for the remainder. Trotanoy was one of the few estates that was not destroyed in the frosts of 1956, and therefore has some of the oldest vines in the region.
