When I recommend wineries for a tour, it is usually based on several criteria. First of all, they must have a premium quality product and a nice facility. Michael pouring some of Sam Sebastiani's finest wines in his private wine library for Quality Tours guests. Also, I have special arrangements at those I most often recommend, such as tasting in the wine makers' private wine libraries and access to wineries that are closed to the general public. Otherwise, the world renowned cuisine of the area may be sampled at any of the many fine local restaurants.
Advanced planning is important to ensure availability at wineries and restaurants.
