French winemakers are concerned that President Nicolas Sarkozy's teetotal ways and clean-living image give the wrong impression of France.
'Everytime you see him on TV he's jogging. He doesn't like eating, he doesn't like drinking, he doesn't represent the culture of France,' said Serge Dombierer, who works for the Chateau de Mauvanne vineyard in Provence in southern France.
'President Jacques Chirac, at least he knew how to put the drinks away,' he added of Mr Sarkozy's predecessor, who could often be seen enjoying wine and beer in visits around the country.
In response to reports that he may have been drunk at a recent press conference, Mr Sarkozy said that he never touches alcohol.
Some producers say he should taste wine and then spit it out as winetasters do, just to show he was interested in a product that enshrines many French traditions.
The wine industry accounts for thousands of jobs and a slice of exports.
'I don't think it's good. He could at least have the intelligence to take it in and spit it out,' said Vincent Charleux, a winemaker for Gerard Bertrand.
He added: 'Given that wine is in crisis in France, he could at least make an effort. It gives a negative message.'
Many French winemakers are struggling with plummeting domestic consumption and fierce competition from new world producers such as Australia and Chile.
