This was a surprising interesting tour which described how the Muga family continue to make wine following traditional techniques, eschewing modern apparatus and chemicals. For example, they use 350 egg whites to clear the contents of a 3 metres wine vat. This process takes a month.
The attached slideshow follows the grape from vat to barrel to bottle to glass. Well worth the ten euros for the 90 minute visit.
