To graft or not to graft

摘要

Many growers are looking at reworking vineyards in an effort to better meet winery expectations and keep pace with the ever-changing popularity of different winegrape varieties. There seems to be a consolidation of what varieties work best in particular regions and have the greatest value for growers and wineries into the future. Field grafting, or top working as it is sometimes known, is a popular option for reworking vines to change varieties or clones. There are many questions growers will ask when comparing this option to replanting and I will endeavour to provide a few answers.
