Reims-based Champagne producer Louis Roederer is switching from green glass to brown for its non-vintage and vintage cuvées. Roederer is already bottling its 37.5cl sizes in the new colour glass and the 75cl size will begin rolling out in 2010.
“Green glass filters out 92% of ultraviolet light,” says chef de cave Jean-Baptiste Lecaillon, “but brown glass gives better protection at 96-98%.”
Roederer’s top-end deluxe cuvée Cristal will continue to be bottled in clear glass, with its signature yellow cellophane wrapper already achieving the higher level of 98% protection.
The move to brown glass is a question of house preference, adds Lecaillon. “Normally 92% protection is enough. This is all part of our search for perfection.”
