In regions where there is a strong culinary tradition and local wines, it is a large part of the fun of travel to discover the local produce. Germaine and I enjoy surveying the produce in local food shops and particularly markets of which there are fine examples in many European towns. When we are self-catering, we naturally give priority to local produce and I would be very unlikely to chose, say, a Tuscan wine when dining in, say, Umbria. I always try to bring home with me a good sample of the wines and olive oils from regions where I stay.
At home in Belgium it's rather different. The country has a strong culinary tradition which is a sort of local variation on a broadly French theme and most of what we eat is prepared in this way but sometimes we will eat imported meat and poultry, usually from France, where this gives a quality boost. Vegetables bought from local farms invariably have more flavour than those bland products imported from Dutch mass producers. There is hardly any Belgian wine so that is not a realistic option. Special Belgian beers are excellent but I prefer to fill my daily alcohol quota with wine most of the time.
