Despite not achieving Cru Bourgeois Exceptional status in the 2003 classification, Château Rollan de By, acquired by Jean Guyon in 1989, offers a cru bourgeois of excellent quality. The 52 hectare vineyard is dominateed by Merlot (70%), Cabernet Sauvignon (20%) and Petit Verdot (10%).

Rollan de By wine is aged on the lees for three months and stirred for three months, after which it is transferred to barrels and vats (95% French oak and 5% American oak). The result is a wine that combines concentration, structure, finesse and elegance. It is a wine that very quickly becomes pleasant to drink.
