In this week’s blog I want to discuss the term “proprietary blends” or “proprietary red wine.” Neither of these terms have an actual legal definition in the wine world however, a “proprietary” wine or blend is a wine that the winemaker or winery does not want to reveal the actual blend or variety of grapes used to make the wine.
Most of the proprietary red wines are Bordeaux inspired wines. In some cases the term “Bordeaux Style Red Wine” is substituted for “proprietary blend” or “proprietary red blend.” In order to be considered a red wine, no variety in the blend may exceed 75% of the blend. Bordeaux wines are always blended from Cabernet Sauvignon and Merlot, although at times winemakers also add Petite Verdot, Malbec and Cabernet Franc. Proprietary red wines are a blend of wines with no one dominating variety of wine.
Most wines labeled “proprietary red wine” don’t reveal the actual wines and percentages of the wines used to make the wine. It’s a marketing ploy as well, as the wines are generally the wineries top red wines.
Some examples of wines called proprietary wines are:
- Joseph Phelps Insignia
- Duckhorn Vineyard’s The Discussion
- Opus One
- Pahlmeyer Proprietary Red
- Sloan Proprietary Red
- Melka Estates Proprietary Red
These are just a few well-known proprietary red wines produced in California.
