This is from a dinner I'd attended where two people brought older Gruners from FX Pichler: viewtopic.php?f=3&t=24186
1997 F.X. Pichler Grüner Veltliner Smaragd 'M' - Austria, Niederösterreich, Wachau
A little muted compared to the Kellerberg (which was just an insane wine and would have overshadowed pretty much anything poured alongside); quiet aromatics with some white pepper, smoke, white fruits and green herbal notes on the nose. Spicy white fruits, beans, herbs and minerals on the palate with good acidity and a medium-long finish. Tasted the leftovers the next day (thanks Stephen!) and it seemed a lot more open and focused - seems to need a bit more time and patience. (93 pts.)
1995 F.X. Pichler Grüner Veltliner Smaragd Dürnsteiner Kellerberg - Austria, Niederösterreich, Wachau
Pale golden yellow colour with an incredible explosive nose that soars from the glass with aromas of white fruits, beans, green herbs, smoke, honey and steel, unravelling even more with air to show elements of flowers, rocks and coffee - so much going on here that it's beyond description, and I could have happily kept smelling this through the evening if it didn't taste so great. Just insane on the palate with almost every flavour element you can possibly imagine in a wine; there's fruit, metal, spice, rock, herbal elements and crazy smoky/ashy notes that all combine seamlessly into a silky, glossy mouthfeel that retains laser focus and lift with a ton of acid and a very long finish. What a wine! (98 pts.)
I tasted the '97 the following morning and it was superb - the '95 Kellerberg on the other hand was one of the very top wines of the night for everyone at the dinner, and it's among the greatest wine experiences I've had yet. As good as any of the older German or Alsace experiences I've had.
