Remich is the centre of Luxembourg's wine industry and the main cave or winery is St Martin. Producing white and sparkling wines, the latter known as crémant, St Martin's offers interesting tours which delve into the méthode traditionelle used to process their sparkling wines.

This process, like champagne production, traditionally involved turning each bottle by hand. Guides at St Martin are adamant that this age-old process is still carried out, though some in the industry claim all the large caves now use machines to turn the bottles. The tour winds through cool, damp tunnels hewn in the rockface and ends with a free glass of bubbly.
