This is a spin-off of Colin-Deleger, where Michel Colin divided most of his vineyard holdings between his two sons, Bruno and Phillipe.
In vintage 2005: according to Stephen Tanzer, he practices less batonnage than his father (Colin-Deleger) and brother Bruno. Stopped stirring the lees in December 2005. Target free SO2 raised to 40 ppm starting with this vintage. According to Tanzer, the wines are less lush, but more precise.
