The partnership of the Croser family, Champagne Bollinger, and the Cazes family from Chateau Lynch Bages in Pauillac, Bordeaux is founded in a strong mutually held belief that some pieces of ground are much better than others for the production of fine wine.
What was chosen was Chardonnay fruit from The Tiers Vineyard (planted by the Croser family in 1979), Cabernet Sauvignon vines on the Whalebone Vineyard (originally the Koppamurra Vineyard just north of Coonawarra), and a revolutionary Pinot Noir vineyard ten kilometres from any other vineyard in the middle of, and at the highest point of, the Fleurieu Peninsula.
The mission of the partnership is to maximise the quality of the wine from these three "distinguished site" vineyards, regardless of cost, which implies producing only tiny quantities of wine.
