Think the Roderer Champagne house isn't serious about their product? Just look at their description of the 2010 vintage growing season:
"The Champagne region experienced a particularly cold winter marked by severe frosts. Bud-break in the vineyards was late, between 19 and 22 April. Spring and early summer were cool and dry, allowing very high quality work on the vines. Flowering occurred between 16 and 19 June, with considerable differences between the sectors and even within the same parcel, due the delayed effect of the winter frosts.
The lack of rainfall made itself felt in the vines towards the end of July. After a very dry month of July, August brought the desired rain, with the equivalent of up to 3 months of summer rain falling between 14 and 16 August. These large amounts of water were beneficial to trigger ripening. The harvests began on 13 September at Aÿ, 14 September at Avize and 15 September at Verzenay."
This 2010 vintage is a blend is 62% Pinot noir and 38% Chardonnay with 15% of the wine vinified in oak tuns without malolactic fermentation. To produce its rosé champagnes, Louis Roederer uses the saignée (skin contact) process after cold pellicular maceration that lasts from 5 to 8 days in the liquid phase. The Rosé 2010 cuvée is aged for 4 years on lees and is left for an additional and minimum period of 6 months after disgorging to attain optimum maturity.
