Château Trotanoy relies on an almost monolithic expression of Merlot, the king grape variety of the Pomerol appellation. Merlot is the dominant variety, representing approximately 90% of the vineyard, complemented by Cabernet Franc for the remaining 10%. Recent vintages bear witness to an adaptation to climatic evolution, with, for example, 100% Merlot vinified in 2023. This dominance of Merlot on deep clay soils explains the velvety texture and aromatic richness so characteristic of the estate's style.
