I worked at a wine store once. One of the managers there told me that in Italy most of the wine makers will be sure to always evaluate their wines with food while a smaller but still a significant number of wine makers in France will do the same.
I'm not saying that I've never taken a glass of wine without food. But if I'm having a glass around the house even then I'll toss some nuts or a piece of ham into my mouth while drinking.
How often do you drink wine without food: always, sometimes, never?
