In 1986, Heemskerk was joined by the noble House of Louis Roederer in a pursuit of the definitive Australian sparkling. Louis Roederer shared in the belief that the climate and soils of Tasmania, so similar to those of the great winegrowing appellations in Burgundy and Champagne, were ideal for the production of finely structured Methode traditionelle. The essential Chardonnay characters of citrus and stonefruits, mingle with the rich autolysis of almonds and brioche, to build a rich and creamy, textural weight of fruit on the generous palate.

The Heemskerk Vineyard was established in 1975 at the heart of the Pipers River district, the birthplace of Jansz Tasmania. The diligence of the team that tends the vines is rewarded by parcels of the highest quality fruit. Attention to detail in the vineyard, with crop thinning and disease monitoring, are essential to great winemaking. Every block of the Jansz vineyard is individually harvested by hand and treated to a gentle vinification, batch by batch, before a well considered assemblage. Four years ageing in bottle on yeast lees achieves classical yeast complexity in the final wine. Much of the finished wine is fermented and aged in French oak hogsheads for nine months.
