Mis en bouteille au château

Mis en bouteille au château is French for "bottled at the chateau". It indicates that the grapes were grown, fermented, aged, and bottled on the property without blending from any other estates.

The term mis en bouteille au domaine is sometimes seen; it is identical except that it refers to a domaine, rather than a chateau, implying that multiple vineyards belonging to the producer were used.
