Why is it that even water in a wine glass can be relaxing and comforting?

I used to drink.. but haven’t for 4 years. (Save a couple slip ups… and by a couple, I mean 2)

Now, I drink alcohol free stuff, or sparkling juice from a wine glass when everyone else is drinking, or when I wouldn normally have a beer or wine (and not always.. on occasion..)

But even if I pour my milk or my water into a wine glass and sip it, I feel the same amount of relaxation as the real stuff.

Do you think its all a mind over matter thing? Just the familiarity.. my subconcious remembering that holding this type of glass.. drinking from it.. brought relaxation and comfort?

Or do you have another theory?
