What distinguishes Mason's wines from all the others is that he enjoys and adheres only to making wines that are true to their varietal character. How he achieves this trueness and consistency is by using the same vines year after year and by spending much time in the vineyard prior to harvesting. Mason believes in letting the fruit show through in the wine and not to add a lot of processes and unnatural enhancements. He considers himself a California style winemaker.
Mason also believes that Yountville, with it's perfect geographic location; in particular, the Yountville Hill, that embraces the cooling ocean breeze and fog during the warm growing season, is the ideal climate for the development of Merlot grapes. It is here that he hand selects his grapes for his Merlot.
