I am planning to to go with my Dad on a wine tasting tour for his 55th Birthday. He is an incredible man, who is very passionate about wine. Although he knows his favorite vineyards, I was hoping people could offer some suggestions for exceptional tasting experiences. He LOVES wines produces in the Rhone style, but also enjoys Syrah. An example of some of his favorite producers are Tablas Creek, Ojai Vineyards, Qupe, and Alban. Any suggestions would be greatly appreciated. Like I said he is well versed in the wine world, but I would love to impress him with some suggestions. Thanks!!
