No grape is used unless it is in peak condition, no parcel of wine is considered unless it lives up to the most exacting standard. Only select vines that have made the grade are considered. In a declassified year some Thomson Reserve fruit (from some of the oldest Shiraz plantings in Victoria) can be included. Unique factors of soil and climate make a contribution. Cold to very cold winters, frequently dry and cool summers, with occasional bursts of hot weather are the norm. Fruit is hand selected, sorted and vinified by small batches in open fermenters, followed by rigorous barrel selection. Matured in a selection of new and used French and American oak barriques and puncheons for a year.
