Champagne ban at Conservative conference

Apparently the bars have been told not to serve champagne at the Conservative conference as it might suggest a mood of triumphalism - although it was possible to get it at the New Statesman reception last night.

I wonder what would be an appropriate drink to suggest a subdued mood of controlled anticipation? At the moment I cannot think of anything, although perhaps a rather dull red wine might fit the bill.

Any suggestions welcome.
