Definition - What does Topworking mean?
Top working in the vineyard is a method to change the variety of grapes which are grown by grafting. This is usually done to meet current market demands and is usually only a short-term solution.
While it is a cheaper solution to planting new vines, the grafts are not always successful in large numbers.
WineFrog explains Topworking
Top working is also a practice used to graft on new varietals to a root stock as other grafts are failing or they are not producing to certain desired standards.
Top working should only be performed after the benefits and risks have been assessed.
- Ability to adapt to market demand and up to full production by the second year
- Low impact on cash flow
- Less time needed to obtain needed planting material
- Lower cost than new plantings
- Variability in the age of vines
- Reduced yield or decline in health of vines on long-term
- Rapid growth of new graft, thus putting pressure on graft union making it vulnerable to breakage
