Pinot gris
Origin:
Pinot gris is probably a mutation of Pinot noir. The only ampelogaphic difference is the colour of the berries. While Pinot noir has blue berries, Pinot gris has grayish-blue berries. In Pinot gris you still can find mutations of the colour of the berries (green/yellow berries or blue berries).
Synonyms:
Ruländer, Grauburgunder, Tokay d'Alsace, Pinot grigio
Requirements to the vineyard site:
Pinot gris needs good or very good slopes to get his strong body which he needs.
Spread:
Primarily Germany, Italy, France and Austria. Because of the "Pinot grigio" Boom in Italy it is now planted in the most wine growing regions of the world.
Clones:
Pinot gris don't have as much clones as Pinot noir, and the differences are not that big. Good quality with loose bunches is the most requested type of clone, because Botrytis can be a real problem while growing this variety.
The clones can be divided into 4 groups:
&nbs
compact clones | clones with different types of berries | clones with different berries and small bunches | loose and high yield clones |
D 43 | |||
1 Gm | |||
21 Gm | |||
63 Wm | FR 2005 | ||
FR 2006 | |||
FR 49-207
This is still the most planted clone in Germany. Good yield and sugar content combined with very good wine results put this clone to the top of the planted clones.
H 1
This was also a very widely spread clone selected by Arno Hauser from Bickensohl. He has a good sugar content and a very stable yield. But in the last years it was planted less.
D 42
This is an older clone of the "Weinbauversuchsgut" in Karlruhe-Durlach. It is now in the hand of the Weinbauinstitut Freiburg.
ENTAV-INRA 52
This seems to be the best known clone from France. His yield and sugar content is quite close to the clone FR 49-207. But the problems with Botrytis are a bit lower.
SMA 505
This clone is from San Michele in Northern Italy. It always shows a bit of shot berries, so that the bunches are looser. In years with big problems of coulure the yield can decline, but we never had extremely low yields in our trials. We think a clone which could be interessting.
SMA 514
This clone hast more or less the same characteristics as SMA 505.
In our trials coulure was a bit less then with SMA 505, but yield was mostly less then SMA 505.
ENTAV-INRA 457
This is another clone from France. Like the two clones from northern Italy there is also a affinity for coulure. It is one of the clones with the most loosest bunches.
Bunches are also small.
27 Gm
This clone which was sometimes called 27-2 Gm. He has smaller bunches with a certain amount of small berries, so that they are not compact and will seldom be infected by Botrytis.
FR 2001
This is a newer clone of the Weinbauinstitut in Freiburg. The aim of the selection was to get loose bunches. In the first days after selection it was called FR EA 94-140
Nowadays it is used very seldom, because FR 2003 is quite similar, but the yield of FR 2003 is higher.
FR 2002
For this clone applies the same as for FR 2001. Earlier this clone was called FR EA 94-141.
Also very seldom used nowadays.
FR 2003
Earlier this clone was called FR EA 94-142.
From the groupe of FR 2001 - FR 2004 he is the one which is most used now, because he has the highest yield in this group.
FR 2004
Beside clone Fr 2003 this clones has the highest yield in this group. But normally he will disapper because only clone FR 2003 will be propagated in future.
FR 2008
Also another clone from the Weinbauinsitut. He showed very good Botrytis resistance, but only low yield.
1-30er Gruppe
This group of the 1-30 clones from Geisenheim contains 4 clones which combines a quite high yield potential with good Botrytis resistance. In high yield years the crop can be quite high. (> 20 to per hectare).
The differnces within the group are quite small, so that we merged them in one group. The member of this group are:
- 1-30 Gm
- 1-31 Gm
- 1-32 Gm
- 1-33 Gm
