We have one day to take a winery tour from Melbourne. We will not be renting a car so we will be "forced" to take a tour. We love Shiraz, Pinot Noir and like Sauvignon Blanc. We prefer small boutique wineries that don't get large tour buses. We want a more personal experience. Another smaller consideration might be the scenery. Which area would you all recommended for us? We travel all over touring wineries and live close to the California wine regions.
