Château Rollan de By is a prestigious Bordeaux wine estate in the Médoc region, renowned for its high-quality Merlot-dominant blends. Acquired by Jean Guyon in 1989, the estate has grown from a tiny 2.5-hectare vineyard to 45 hectares of prime Bordeaux terroir, featuring clay and gravel soils ideal for Merlot, Cabernet Sauvignon, Cabernet Franc, and Petit Verdot. The vines, averaging 35 years old and planted at 8,500 vines per hectare, produce wines that are aged 12 months in 90% new French oak and 10% new American oak barrels. Guided by consultant Hubert de Bouard, Château Rollan de By produces 20,000 cases per vintage. These Bordeaux wines show best after 2–4 years of bottle age, reaching peak maturity at 3–15 years. With its classic Bordeaux character, rich fruit-driven profile, and excellent aging potential, Château Rollan de By is a must-try for lovers of premium Médoc wine.
