Freiburg, Dangolsheim and Geilweilerhof

One of our most interesting experiences in the field of Viticulture had been our visit to Geisenheim a couple of years ago and so when the opportunity presented itself, we decided to pay a call on the other two famous German institutes at Freiburg-im-Breisgau (Staatliches Weinbauinstitut) and Siebeldingen (the Julius Kuehn Institut at Geilweilerhof). This was not unconnected with the time of year in our little experimental vineyard in the Thames Valley. Always on the lookout for the latest advances in PIWI varieties for planting, we hoped to find out what the latest research had produced.

Our UK source Derek Pritchard of Dunkery Vineyards in Somerset had recommended Souvignier Gris as something to plant. We noticed that it was the Staatliches Weinbauinstitut Freiburg that had developed this variety - a combination of Cabernet Sauvignon and Bronner.

We can't recommend a visit to these research institutes highly enough. One is received by appointment by the most senior staff available who are only too happy to spend their valuable time sharing their discoveries with small-fry hobbyists such as ourselves and opening bottles for tasting from their micro-vinifications from the many grapes they are breeding. This is hugely informative and exciting because it represents the future for many growers in marginal or difficult climates whether in the North or in the Tropics and increasingly in traditional wine-growing areas where sprays against weeds, insects, diseases and so forth are on the point of being outlawed,

We have seen in this blog that this is the case in Italy where copper will be banned from 2017 and growers are rushing to plant Solaris and other No-Spray varieties to beat the ban. Solaris was developed in Freiburg.

Indeed, some of the most successful resistant Hybrids have been produced there and from the other two famous institutes. The best known among these are


Cabernet Cortis





Immense progress has been made since the early hybrids such as Triomphe d'Alsace, Marechal Foch, Leon Millot, Madeleine Angevin, Seyval Blanc, Seyve-Villard etc. Now 'foxy' flavours are a thing of the past and some varieties have been granted Vinifera status even though their ancestry is far from 100% Vinifera. Even these institutes are beginning to withdraw varieties only a few years old because they have better ones to replace them. At Geilweilerhof for example we were told that Sirius and Orion had now been replaced by Calardis Blanc and Felicia.

Our first appointment was in Freiburg, a city well known to us from the German studies of our youth. In those days (early 60s), the wines of Baden were not as highly considered as they are now, so together with the Weinbauinstitut, progress is in the air.

We were received by Ernst Weinmann, Referatsleiter Weinbau, Versuchswesen and his associate, both immensely knowledgeable and helpful. They immediately gave us fact sheets on most of their current varieties which we sorted out into different piles once it was clear that we already had Johanniter, Helios and Solaris but were interested in other resistant vines demanding the least attention but which grew vigorously in an upright direction (some tend to grow quite a lot sideways which entails a lot of pruning).

Here immediately was the one we had come to learn about; Souvignier Gris

Cabernet Cortis and Prior may not be suitable for the UK

Bronner (White) and Monarch (Red)

Muscaris white

We tasted the Souvignier Gris first. Rumours as to its similarity to Sauvignon Blanc were well founded and we decided then and there that this was a variety for us.

The Muscaris didn't persuade us to alter our decision to go with Souvignier Gris.

This Cabernet Cortis was made by an Austrian gentleman well into his 80s. It was in a Halbtrocken style which didn't obliterate the Cabernet Cortis from the Ahr we had enjoyed a few years back.

The great thing about Freiburg im Breisgau is that in minutes you can be in Switzerland or France, or rather Alsace. We had decided to visit a Pepiniere or plant nursery in a place enjoying the name Dangolsheim. The reason was that they had some Knipperle vines. Knipperle is an offspring of Gouais Blanc as so many grapes are. It used to be found all over Alsace in the 19th century but gradually lost ground being relegated to Zwicker blends (NB. not even Edelzwicker) due to its tendency towards neutrality and finally relegation to the dustbin by the powers that be who limited permitted grapes in Alsace to just a handful from the dozens which were to be found there previously. Knipperle is also a parent of our Sorgenkind, Triomphe d'Alsace.

Vincent Zerr is the owner of Pepiniere des Boarmies. You can get an idea of what he is about from the welcome on his website;

Pépinièriste viticole et collectionneur depuis 1987
Producteur de plants de vigne pour
Les amateurs et les passionnés
Variétés anciennes et nouvelles
Pour les raisins de table
Pour la décoration
Pour la collection

His wife and son run the bakery where grape juice from unspecified varieties were on offer. 

M. Zerr took us down the hill to his tunnels. He explained that he has 470 varieties of vine in his collection. That is Fourhundredandseventyvinevarieties only! They are mostly dessert grapes. If some vine grapes are present it is purely down to the conservation of historic varieties of Alsace-Lorraine. For legal reasons these cannot be used to make wine or anything else. That is why it is impossible to taste wine made from Knipperle anymore.

How he was able to pluck out a Knipperle we can't imagine. Like most of the others it's not even on his website. 

We were also attracted to something called 'Raisin de la Terre Promise'.

Raisins de la Terre Promise held up for scale by the young Zerr fils
  Looking it up, it is so named due to its huge grapes, fabled to be the ones brought to Moses by his men sent to spy out the land of Canaan.

Kora Shonneol

Kelim Bormok, Kelim al Bormok or Kelim al Barmak

Similar varieties, Kora Shonneol and Kelim Bormok come from Uzbekistan and are among the most exotic of M. Zerr's collection. Strangely enough, Raisin de la Terre Promise is found in modern day Israel where it is known as Neheleshol. It also occurs in South Africa where it is called Palestine, Palestinian or Grape of Palestine and Romania where it makes unremarkable wines. Perhaps not surprising for a dessert grape.

Raisin de la Terre Promise has now found a home in Spain, our next stop

On the website other obscure varieties included

Baco Noir (sold out!)
Muscat Bleu
Precoce de Malingre


M. Zerr's experimental vineyard beyond two of his 50 Apricot trees.

Not content with his 470 grape varieties, M. Zerr is also into Apricot Trees (50 varieties) and wheat. He offered to show us his wheat varieties but we declined.

In conversation we learned that there is an Alsacian association of like-minded people devoted to maintaining their heritage of bio-diversity. The association is called Kerna un sohma - Pips and nuts in Alsacian dialect. M. Zerr was convinced the EU was hypocritical in banning all but a few varieties of vine, wheat, apricots etc. always making out it was for sanitary reasons whereas in practice this gave opportunities to commercial interests selling seed etc. He hinted that there might be  growers below the radar who persisted with the old ways.

M. Zerr is not an eccentric or a hobbyist; he is consulted in many countries (he has even been to the Republic of Congo to advise on the creation of a vineyard) and has a client list all over the world.We were fortunate indeed to meet him and hear about his important work and grateful to take away two vines in plastic pots; a first for Slotovino.

Next, Geilweilerhof, near Landau, north of Karlsruhe.

The approach takes one up a so-called Rebenlehrpfad dotted with notices explaining matters for the uninitiated.

We had see photos of Geilweilerhof and its tower and other features had given it a slightly sinister atmosphere but apparently this has nothing to do with the Julius Kuhn Institute having been built by the previous owners.

The Institute itself is housed in this more modern building

Indeed the Director, Dr. Reinhard Toepfer (left) and his colleague Rudolf Eibach in charge of Zuechtung (breeding) couldn't have been more charming and welcoming.

Our conversation followed a similar course as that in Freiburg and similar tech sheets were produced;

GF.92-22-6 and Felicia

Calandro and Reberger

Gf.Ga - 52 - 42 and Villaris

We had already put in a few minutes research in the tasting room and Felicia had already made an excellent impression. Dr. Toepfer and Herr Eibach recommended Calandro and Reberger in particular.

We later tasted these in the tasting room and bought a bottle of Felicia which we drank with pleasure a couple of nights later.

On enquiring if there was a good 'Rebschule' neaby, they referred us to Rebschule Wolf in Umstein, a suburb of Bad Duerkheim. 

So bidding Geilweilerhof Auf Wiedersehen, we trundled off to Umstein which is positively heaving with Rebschule, one actually called Krapp.

But here was Wolfs Brunnen, Winzer. Weinprobe, Verkauf (Wolf's Spring, Producer, Wine-tasting, Sales)

Frau Wolf, left and colleague preparing vines for planting

Entering with some trepidation we were asked by Frau Wolf what our visit was about and when we mentioned vines she asked which ones we wanted. We asked her which ones she had. That is a question which has caused consternation before at other Rebschule. Stocktaking at the end of a no doubt busy season must be well nigh impossible. We were actually after Souvignier Gris. Frau Wolf conducted us into the presence of her husband in an inner sanctum. Herr Wolf turned out to be a very jovial character delighted to help.

He decided that what we wanted was GF.93-22-6, a crossing of GF.GA-47-42 (Bacchus x Seyval) x Seyve Villard 39-639.

It became clear we were not going to leave without 25 Stueck of this variety. Even the obligatory agreement with Geilweilerhof could be sent for our signature. Meanwhile a bundle of vines in a brown plastic bag was loaded onto us.

We didn't object as we had taken a shine to the Wolfs and reckoned they knew what they were talking about. We also have a faiblesse for varieties so obscure they don't have a name yet. We might put  GF.93-22-6 next to our GM8107-3.

Herr Wolf then conducted us to the tasting room where he urged a sample of something called Aromera on us.  It came from a colleague; a Rebschule in Austria.

He also urged us to return in July when up to 1,000 people descend on his property to taste up to 36 wines he makes in micro-vinification so buyers of his vines may know what to expect.

Later we learned that Freiburg had located 25 1 metre long vines of Souvignier Gris for us. How kind everyone is in the world of Rebschule and wine research institutes.
