I made this wine a few years ago, when it was a 7 L. kit... this looks like the new 10 L. kit....It made a very nice wine, but it did not make it a year before it was gone...
...So many wines, so little time and not enough money to try them all..
I've not made the VR Riesling, but I have made the Piesporter and it is excellent. No need to age for a year, but it is enjoyable shortly after bottling but definitely better after 3 months. I had no need to filter. Just clarifiers and gravity and it was brilliantly clear.
I haven't made the Reisling, but just bottled the Gewertz. It's fantastic. Clear as a bell w/o a filter. Just like FineWino said, time and gravity. I started this kit in August, just to busy to bottle until now.
