Hello there , welcome to Wine World . Let me know if I can help you out at all .   Um , yes , please , I could really use some help . I'm going over to my boss'house for dinner tonight and don't know what kind of wine I should bring .   OK , do you know what kind of food will be served ?   Well , his wife is Japanese . He said she makes really good sushi .   Hmm , that's a bit of a challenge . Sushi is notoriously difficult to pair with wine . Well , let's see . have to be a white wine , of course .   Why ? Wouldn't a red wine go well with sushi ?   No , I don't think so . Sushi is a very delicately flavored food , and red wine would be a jarring contrast . You need a white wine , which has more subtle flavors , to complement the fish .   I see . So should I get a bottle of Chardonnay ? That's a white wine , right ?   Yes , Chardonnay is a white wine , but I'm not sure it'd be your best bet . Chardonnay is one of the more fullbodied whites , and tends to be a bit oaky . I'd suggest that you go for something brighter , like this Sauvignon Blanc from New Zealand .   Sauvignon Blanc ? What's that ?   That's another varietal , or type of grape , just like Chardonnay .   Let's see . The label says it's got " attractive citrus and grassy aromas that give way to crisp , mineral flavors and a bonedry finish . Serve chilled . " Oh , no , how long will it take to chill the wine ? I'm on my way to the dinner now .   It's OK , don't worry , we'll just choose a wine from the cooler . We don't have quite as extensive a selection over here , but ... this Rhone Valley white would be lovely .   All right . What varietal is that ?   Well , this is a French wine , so they don't always specify the varietal on the label . The French believe that the soil a grape is grown in is one of the most important factors in the final flavor of the wine . This wine is probably a blend of a few different types of grapes , mostly Viognier , I'd guess .   And you think this is a good wine ?   Yes , this is one of our best-sellers . It's not quite as dry as the Sauvignon Blanc we were looking at earlier , which means it's more approachable . It's light and crisp , with a bit of a vanilla aroma .   Perfect ! I'll take it !
