Pay attention to the region Whether you’re shopping at Wine Insiders or hoping to redeem a different credit card offer, Paton says certain regions and grape combinations are “safer bets than others.” “A lot of people think they hate chardonnay, or they love sauvignon blanc, only to order one and not realize that it does not taste like the ones they like,” Paton said in an e-mail. “This is likely because they are used to a grape from a certain place, and that makes a huge difference in what it tastes like.” So, if there’s a wine you really like, pay attention to where it’s from and keep that in mind if you’re ordering a new wine online.
