Tahbilk vineyards are grouped along the banks of the Goulburn River and an anabranch of it that flows through the estate. The vines are grown at around 134 meters elevation of gently undulating and flat terrain. The soils are sandy loams with ferric oxide content, which varies from very fine sand near the anabranch to denser loams on the plains. Tahbilk has Shiraz vineyards dating back from the 1860s to the 1990s. The oldest surviving block is the 1860 block; planted on its own roots in sandy soils, which has made it impossible for phylloxera to colonize the vine roots. The vines are planted on single wire trellises, with a mixture of head and cordon training; all are cane pruned. Tahbilk's vines are sustainably cultivated; composting and mulching take place which improves soil health by promoting earthworm activity. Mulching helps to control weeds and conserves water, reducing vine stress. The old vines are hand-picked while younger vines are machine harvested.
