One third of Italy’s vines should be replanted or pulled out because they are making unmarketable wines, Marchese Piero Antinori says. Despite Italy’s success in global markets, the leading producer and former Decanter Man of the Year reckons 30% of vines are making wines unacceptable to today’s markets. According to Antinori, the problem is particularly acute in central Italy, where there are thousands of hectares planted to Trebbiano, ‘a not very interesting grape’, and in southern Italy – particularly Sicily and Puglia – where many vineyards are producing huge yields of 250hl/ha (hectolitres per hectare).
