(Wines&Vines) - Many winery and vineyard owners would like to find out how much their property is worth and present it in the most favorable manner in preparation for a sale. The Seminar Group recently presented a program about that subject in conjunction with another meeting about buying and selling vineyards and wineries. While designed for lawyers needing yearly education, the information was equally valuable for property owners and other professionals who attended. The seminar began with an explanation of how wine businesses are valued. Naturally, overall market conditions should be the first consideration. Prices were generally much higher before the economy collapsed in 2008, though they are rebounding.
