With the local trend toward grape sales to various private and cooperative wineries in the 20th Century, understanding of suitability of grape varietals to historic vineyards among South Tyrolean growers was largely lost. Increasingly, grape growers produced whichever varietals the market demanded. Today, Laimburg Research Centre is working to identify the ideal microclimate for each varietal. This process involves experiments like cultivating specific varietals at varying altitudes and vinifying the grapes from each sample site separately. Some 20 different varietals are currently under examination for their potential in South Tyrol, ranging from exotic international vines (such as Tannat, Petit Verdot, Syrah and Incrocio Manzoni) to those with a longer history of cultivation in the area.
