<s>[INST] The next text is a question of a member of the European parliament:"Winegrowers in the Patrimonio appellation in Corsica are today facing a variety of problems linked, for example, to the difficulties involved in shipping merchandise within the EU Member States or the increasingly protectionist attitude which many third countries are taking towards wine imports.  The administrative complexity of the customs documents to be supplied in connection with intra-Community exports can be discouraging. A simple authorisation procedure for eight cases of six bottles may take up to three hours. Very often, this effectively prevents small producers from exporting their wines at all, since they simply cannot afford the time needed to send even a few cases to Germany, Italy or the Czech Republic.  Winegrowers sometimes also have to deal with the ultra-protectionist attitude taken by certain third countries towards imports of European wines. The experience can be a frustrating one. Having recently been selected by the Société des Alcools du Québec (SAQ — Quebec Wines and Spirits Procurement Agency) to take part in an invitation to tender for white wines from Provence and Corsica, a group of Patrimonio winegrowers were asked by the SAQ to dispatch samples of their wines. However, the winegrowers were thwarted by the complete ban on imports of wines sent as samples or in very small quantities. The products in question are systematically confiscated by the customs authorities.  The waste of time, energy and money resulting from these problems causes many small producers to lose all motivation to export their wines. Is the free movement of wines in Europe thus possible in theory, but impossible in practice? Are Europeans as protectionist in defence of their own products as third countries are in defence of theirs?"
