Options for vineyards: reworking, top-grafting, replanting or removing

Summary

Economic pressures are triggering significant change in many Australian vineyards. Growers are facing increasing global competition, low grape prices, market oversupply and reduced consumption. Large areas of vineyards in NSW are now reaching an age where productivity naturally declines. Many were established during the rapid expansion of the 1990s and early 2000s. Although these vines are not old by traditional viticultural standards, years of drought, waterlogging, frost, and periods of low investment have weakened plant health. As a result, trunk disease, crown gall‑like symptoms and grapevine virus infections have become more common, further reducing vineyard performance. In some cases, the quality of planting material used during the expansion boom may also have contributed to these long‑term issues.

Ageing vineyard infrastructure, such as posts, wires, end assemblies and irrigation systems, is also creating challenges. Decades of machinery traffic and continuous cultivation have led to soil compaction, declining fertility and organic matter, and, on some sites, increased salinity and sodicity. These factors collectively diminish vine vigour and productivity.

Consequently, many growers are now reassessing their options for vineyards with declining yields, poor fruit quality, and rising maintenance costs. Some are also considering how best to deal with abandoned or severely under‑performing blocks. The available choices, reworking, top‑grafting, partial or full replanting, or complete vineyard removal, each have advantages and constraints. Determining the right option, and the right timing for investment, can be complex and site‑specific.
