Darren De Bortoli capitalized on the potential of his Riverina property to become affected by Botrytis cinerea or Noble Rot, a fortuitous confluence of sunshine and light rains, mildew and early morning mists. Candidate vineyards are assessed to determine the optimum harvest time for each parcel of fruit based on sugar content and the degree of botrytis. Each parcel is individually harvested and handled. Vinifications can last from three weeks to three months, as long as it takes. When ferments are complete, batches are clarified, stabilised and filtered. Most components are matured in a combination of new and one year old French oak barriques for a year, a portion remains unoaked.
