The Opawa vineyard is located on the historic river bed of the old Opawa river. The Opawa river was fed from the Wairau river until the Wairau plains were developed for agriculture and flood protection measures were put in place, changing the course of the river and leaving part of the old river bed dry. The stony soils are ideally suited for grape vines but not much else! Water drains freely, which grapevines like, and heat is absorbed from the bright Marlborough sunshine during the day, to be radiated back onto the grapes at night.

​

The vineyard was developed by Nautilus Estate who purchased the land in two parcels in 2001 and 2003. The combined plot is 25 hectares of very stony soil which was wild scrub land before grapevines were planted in surrounding area in the mid 1990s. The vineyard is in a warm, frost free site that ripens early in the season and produces an intensely fruity and fragrant style of wine, with a soft, juicy texture and great overall balance.
