Napa, Calif.—Along with capricious weather and challenging marketing in a weak economy, vineyard and wineries must also worry about taxes. Recent meetings addressed some of these issues and notably offered suggestions for minimizing taxes and related problems. PricewaterhouseCoopers, the accounting firm with a large presence in the wine industry, held a seminar Tuesday about taxes and financial issues. It was attended by CFOs and financial staff from many wineries. At the event, Greg Scott, a 35-year veteran of the company and head of its wine and vineyard practice, shared ideas for minimizing taxes, as did his colleagues.
