Falling wine consumption and too much wine .. where will we end up?

Lots of new or interesting wines are listed as a 'Hand-sell'. But for how long?

Would you hand in your phone in a Restaurant for 2 hours to get a Complimentary bottle of wine?

Do you know the alcohol volume of your favourite wine, and does it affect your buying habits?

Do you buy your wine for 'immediate' consumption or for a future date?
