Restaurants using wine lists on the iPad are reporting increased sales; one restaurant says sales are up 11%.
Mr. Kendall, 43, described himself as a bit of a wine poseur. He has vacationed in Italy and Napa Valley and has a cellar at home, but he cannot remember a label from meal to meal. He knows just enough, or perhaps just little enough, to become suspicious whenever a waiter recommends a vineyard he does not know.
“In the back of your mind,” he said, “you’re always thinking: ‘O.K., is this some kind of used-car special? Did they just get 200 bottles of this?’ “
But Mr. Kendall said the ratings he found on the iPad — by the wine writer Robert M. Parker Jr. — carried credibility. He decided that the price of the cabernet franc was justified by Mr. Parker’s award of 92 points out of 100. “I found a bottle of wine that I never would have tried, and it was wonderful,” he said.
