Napa, Sonoma, Livermore, Woodinville, Rioja this summer..I mostly learn about global wines from great restaurants and wine bars in SF, Seattle, NY, Vegas, etc.
I was lucky enough to grow up in France and have fond memories of the vineyards in my native region, Alsace. I visited Burgundy, the Rhone, and the Loire areas a lot too. I also enjoyed Westport Wineries when I lived in Massachusetts.
