PROPRIETARY WHITE
Creative Blends With a Winemaker’s Signature

Origin & History
“Proprietary” blends gained traction as winemakers sought the freedom to experiment beyond traditional DOC or varietal constraints. While red proprietary blends have long been popular, white versions are increasingly crafted for complexity, balance, and originality—especially in New World regions.
How It’s Made
Vinification styles vary widely. Grapes may be fermented separately or co-fermented, in stainless steel, oak, concrete, or amphora. Blends may include both aromatic and textural varieties, with techniques like lees aging or skin contact used to add depth.
