Tahbilk vineyards are grouped along the banks of the Goulburn River and an anabranch of it that flows through the estate. The water has a tempering influence on the climate. The vines are grown at approximately 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. The grapes come from the single vineyard Madills 1927 block, where the vines planted before 1986 are on ARG rootstocks. They are trained on a single wire trellis with a mixture of head and cordon training, with cane and spur pruning. Tahbilk's vines are sustainably cultivated; composting and mulching take place which improves soil health by promoting earthworm activity. Mulching also helps to control weeds and conserves water, reducing vine stress.
