Sanctus Sanctorum is a highly coveted wine produced only in the best vintages. It is made from the oldest vines of Grenache, which are well over 100 years old, located in Le Crau. The wine is aged entirely in demi-muid and bottled in magnum, a bottle size equivalent to two standard bottles of wine, or 1.5 litres. The magnum bottle size provides several benefits, including a slower aging process, allowing the wine to develop more complexity and depth over time. Additionally, the larger bottle size creates a more impressive appearance when served at events, making it an ideal choice for special occasions.

Clos Saint Jean Sanctus Sanctorum is a small-production wine, and only a limited number of magnums are produced each vintage. The debut vintage in 2007 saw just 350 magnums produced. Though finding a bottle may require some effort and a high price, it is undoubtedly worth the investment for those seeking a truly exceptional wine experience.
