The Colonial Estate is a range of limited-production Barossa Valley wines that are handpicked and vinified using mainly French methods by Jonathan Maltus of Bordeaux's' Chateau Teyssier and Le Dome. .Colonial Estate's approach is deliberately and uniquely French. The wines are handpicked into trays and double-sorted. The reds receive cold pre-maceration, delestages, pigeage, and maceration on the skins prior to ageing in French oak; whilst the whites get whole-bunch pressing and lees batonnage and are fermented with yeasts imported from Champagne . The reds come, in principle from the prime Northern Arc of the Barossa Valley and the whites from the cool-climate of the Adelaide Hills. The wines are produced from vines that are either owned by the Company or are from selected growers.
