This is the second in an occasional series on how business owners are succeeding and struggling with their technology needs. The business: Cannonball Wine (the name will be changing to Cannonball Winery), based in Healdsburg, Calif., is a five-person virtual winemaker. Rather than owning vineyards and processing facilities, the company contracts with various larger companies that provide grapes (mostly from Sonoma and Mendocino counties), as well as fermentation, aging, finishing, bottling and warehousing services, all to Cannonball’s specifications. Founded four years ago with financing from the partners and their families and friends, as well as a Small Business Administration loan, the company is now shipping 35,000 cases of its Cabernet Sauvignon and Merlot a year to wine stores and wholesalers.
