A group of wine industry veterans have partnered together to aggressively buy wine brands in the hopes of eventually taking the venture public.“The market has bottomed out,” said Phil Hurst, a co-founder in the new partnership. “The pricing on vineyards and wineries are at an all-time value right now.” Bill Hambrecht, a wealthy investment banker and longtime vineyard and winery owner in Sonoma County, is teaming up with the existing partnership of Hurst, Paul Dolan and son Heath Dolan, who together own Truett Hurst Winery in Healdsburg.
