Ian Roberts purchased the Riversdale property in 1980 while a university student, and says he paid a record price for the district. The unique feature of the property is its frontage to the Pittwater waterfront, which acts as a buffer against frost, and also moderates the climate during the ripening phase. It is a large property, with 37ha of vines and one of the largest olive groves in Tasmania, producing 50 olive-based products. Five families live permanently on the estate, providing all the labour for the various operations, which also include four 5-star French Provincial cottages overlooking the vines. A new cellar door and French bistro opened in Jan '16. Wine quality is consistently good, and can be outstanding.
