Cheap industrial French plonk, to wash down seriously garlicky stuff. No one complained, as I put it in old decanters. They looked very pretty, all frosted with condensation.
Lesson: set the table with a big white cloth, and fill random old cheap decanters and carafes with basic but decent white wine, well chilled. The added plus, it made sure that everyone had enough wine, without the bother of hovering to top up.
