"M" stands for "monumental" and serves to signify Pichler's Grüner Veltliner Smaragd exceptional complexity and concentration. The first gruner to be awarded this honor, 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. "M" is always a mystical wine, exhibiting opulence and concise minerality.

97 points James Suckling: Enormously concentrated and seriously creamy this is a monumental wine (for which the M stands), but has great balance, too. The finish is extremely clean and long. Better from 2018 with enormous ageing potential.

95 points Wine Enthusiast: This leads with a ripe, tropical whiff of pineapple that's subsumed into a more savory notion of celery-salt and miso. The concentrated palate similarly juxtaposes salty miso with bright lemon notes. In the end, the saltiness triumphs and leaves you wanting more. A compact but very concentrated wine that's full of flavor and has a lip-smacking finish.
