If you are serious about learning about wine and discovering delicious wines, you should spit wine when visiting the tasting rooms of the Napa Valley or any other wine country. There is no way you can visit three to five wineries in one day, tasting five or more samples of wine at each winery, and remain sober. You palate will be gone in short order.
Needless to say, if you are the driver, your only choices are to spit or just roam around the tasting room while the others are having a grand old time.
