Main Ridge Estate was established in 1975 by Rosalie and Nat White in William Road, Red Hill. The 3 ha. vineyard was planted, over a number of years, with the classic varieties of Chardonnay and Pinot Noir.

From the outset the aim has been to make unique wines of the highest possible quality by limiting production to grapes grown on the Estate. Yields are held to very low levels of less than 5 tonnes/ha. (2 tons/acre) and traditional winemaking techniques are used to create wines of great elegance and complexity.

More recently the White family has sold the vineyard to the Sexton family, they retain Nat as a consultant.
