M stands for "monumental" and serves to signify our Grüner Veltliner Smaragd of exceptional complexity and concentration. The first grüner to be awarded this honour, because it presented itself like a landmark, or simply a monument, was one of the 1991 vintage. The grapes for "M" are usually harvested two to three weeks after the fruit for the vineyard-designated wines. Depending on the vintage and growing season, the major portion of "M" is usually sourced from Loibnerberg terraces and a selection of the best fruit from several premium sites.
