The Collio is one of Italy’s most renowned wine-growing regions. Yet many people wouldn’t be able to point it out on a map. Hire a 125cc Vespa and get ready to spend a whole day amongst rolling hills and vineyards stretching all the way to the Slovenian border. Halfway along the route, there’s also a stop-off not to be missed: a visit to the Viarte winery with a tasting of three local wines.
