This is definitely worth a read! I actually found this on a human resource site out of all places! Enjoy and you can thank me later.
1. Know your Audience and their Level of Wine Knowledge. Don’t Try to Bluff the Wine Enthusiast!
2. Learn How to Properly Taste…Aromas, Introduction, Texture, Palate and Finish.
3. Do Not Overindulge. Tasting Does Not Mean Drinking.
4. Drink Water. Alcohol Dehydrates.
5. Do Not Overpour Yourself or Others. At a Tasting, a Single Bottle of Wine May Need to Make it Around the Room.
6. Don’t Taste on an Empty Stomach. Avoid Overpowering Foods.
7. Wear No or Very Little Perfume or Cologne. Be Courteous to Others who are Enjoying the Wine’s Aromas!
8. Enjoy Yourself by Researching a Few Wine Basics Beforehand. (See Below.)
9. Don’t Try to Overpower Others with Your Knowledge. Wine is Largely Art, Perception and Opinion with Only Certain Components of Fact and Science.
10. Never Add Ice to Wine.
11. Please Don’t Make a “Spritzer” with a Nice Bottle of Wine.
12. Never “Top Off” Someone Else’s Glass… Unless You KNOW it’s the Same Wine and they Wish for More of that Same Wine.
13. Learn How to Properly Open a Bottle of Wine Before Attempting. Only Open a Wine Bottle When Invited by the Host to Do So.
14. Rinsing Your Glass Between Pours is Controversial, Especially Using Tap Water. Do Not Leave Water in Your Glass Before the Next Pour.
15. If You’re Attending an Event at Someone’s Home, Bring a Bottle of Wine. Research the Wine, and Tell a Bit About It!
