The grapes are sourced from the single vineyard "Bull Block" in the Omaka Valley. This flat vineyard site is named after the Jersey Stud bulls that previously grazed here. The vineyard is 100% planted with clone 10/5. Originally imported from Switzerland, this clone was responsible for some of the first vineyard plantings in regions such as Central Otago. It is a late ripening clone, which is ideally suited to this vineyard site and the late-harvesting allows for a greater intensity of flavours to be built, while maintaining acidity for freshness and balance. While much of the region is planted with Burgundy clones, this Swiss clone offers a distinctive expression of Pinot Noir. The soils consist of silt loam over clay-loam subsoils. Warm days give way to cool nights and this diurnal temperature swing, coupled with the clay-rich vigour moderating soils, encourages the vine to produce small berries of concentrated juice.
