Know When to Say "No"

Don’t reject a wine simply because it’s not what you expected or don’t like it. The rule for refusing wine is the same as that for refusing food. If it’s spoiled, you can and should reject it. If it’s simply not to your liking, chalk it up as a learning experience. It’s not the restaurant’s fault you didn’t like the wine you chose. If, however, the wine is acceptable, simply nod your head to signify your consent. The waiter will fill the glass of your companion first and then return to fill yours.

• The wine is “corked”—This is a result of a fungus in the cork, which give the wine a musty smell often compared to a dank basement or wet cardboard. If you notice something like that, you may confirm it by sniffing the cork and examining it for signs of damage or decay.
• 
  The wine has turned to vinegar—If the wine tastes or smells like salad dressing, it’s definitely gone bad.
   
• The wine has refermented—The tell-tale sign is if it looks bubbly or tastes “fizzy,” even though it’s not a sparkling wine.
