Planning notes for a corporate event

Most corporate guests self-limit to 2 drinks max - don't over-order.
Wine outsells beer 3:1 at corporate events - flip your usual ratio.
Many corporate guests leave within the first ninety minutes, and the early stretch is the busiest.

Focus on quality over quantity for corporate events. Stock premium wines and craft options rather than bulk quantities. Have elegant non-alcoholic options visible - many professionals choose not to drink at work functions. A sophisticated sparkling water with citrus is always appreciated.
