The vineyard has some 200 hectares under vine which includes the rare French Rhone Valley whites of Marsanne, Viognier and Roussanne; and the Rhone reds - Shiraz, Grenache and Mourvedre. Also planted are the traditional varieties Cabernet Sauvignon, Merlot, Cabernet Franc, Chardonnay, Riesling, Semillon, Sauvignon Blanc and Verdelho and new age rising stars Tempranillo and Savagnin.
Vineyard plantings extend back to Tahbilk's founding with original pre-phylloxera Shiraz vines still surviving from 1860 - an eponymous wine produced from them since 1979. Tahbilk is further blessed with an abundance of further "old vine" plantings including Shiraz from 1933 (the prime source for Tahbilk's 'Eric Stevens Purbrick' Shiraz releases), Cabernet Sauvignon back to 1949 and Marsanne from 1927 (a "sister" white release to the 1860 Vines Shiraz).
A technique favoured in Provence is then used to increase texture and mouthfeel, by mixing the cold juice (including the pulp and solids) with nitrogen gas briefly each day over four days.
The wine is then racked to produce clear juice and fermented with a specific Rose yeast at 10/14 degrees for 2 weeks prior to being filtered and bottled.
