Mitterberg IGT is a geographical designation from the province of Bolzano in Südtirol, the German-speaking corner of northern Italy. The name is indeed German and refers to a ridge near the town of Bolzano itself, and it immediately tells you something about the landscape here, where mountains, valleys and large swings between day and night shape the wines.
IGT sits at the freer level below DOC and DOCG, and that is much of the point of Mitterberg. The province of Bolzano is already a subzone of Alto Adige DOC, so this designation is used for wines that fall outside the DOC's rules. That makes it relatively little used, but also interesting, because here you often find the more experimental or unconventional choices of grape varieties. A wide range of grapes is permitted, and if a wine is sold as a varietal, the named grape must make up at least 85 percent.
The range is broader than many expect. Under Mitterberg IGT, white wine, rosato and red wine are made, but also early novello versions for young enjoyment and sweet passito wines from dried grapes. In other words, it is a designation that gives winemakers room to work freely, without letting go of the anchoring in a very specific place.
With us, Mitterberg IGT is a fine entry point if you would like to explore Südtirol from a slightly lesser-known angle. If you want to go further with the region's more classic expressions, you can take a closer look at Alto Adige, and if it is the fresh, alpine white wine style that appeals, Pinot Bianco is an obvious next step. Either way, it is a designation that rewards curiosity more than fixed expectations.
