This is a spin-off of Colin-Deleger, where Michel Colin divided most of his vineyard holdings between his two sons, Bruno and Philippe.
In vintage 2004: Bruno states that he follows most of his father's techniques except that “he may stir the the lees a bit longer in the spring.” [Ed Note by Don Cornwell–Colin-Deleger was already one of the estates with major problems in terms of premature oxidation and anecdotally was a relatively low S02 user as well as one of the longest lees stirrers in vintage 2000. So this statement is anything but a good sign in my view.]
In vintage 2005: M/L's completed in January-February, but stirred the lees until early May; free SO2 level increased to 40 ppm beginning this vintage
In vintage 2010: Currently bottling at 35 pmm free SO2.
