2003 Petra Alba

2003 Petra Alba, Anjou Villages Brissac
2003 Anjou Blanc

During the past few days we’ve enjoyed these two wines from Christophe Daviau’s Domaine de Bablut (Brissac–Quincé). The Daviau family have been vignerons here since 1546. The domaine is now biodynamic.

Both wines are marked by 2003, the year of the heat wave in France, particularly during August. In the Loire the vintage was the earliest since 1893 with picking beginning in the Pays Nantais, Touraine, Quincy and Reuilly around 18th August. Even in Sancerre the vintage started in early September.

We drank the 2003 Petra Alba, which is 100% Cabernet Franc grown on limestone, with a simply roasted free-range chicken. Deep coloured and with rich, full fruit – plums and prunes. Tasted blind you would think that this comes from the south of France – the effect of the sunshine and high temperatures of 2003. For me, although CRM disagreed, there is a slightly roasted quality to the fruit particularly in finish that detracts a little from the wine, although it still a very enjoyable bottle.



The 2003 barrel-fermented and aged Anjou Blanc (100% Chenin Blanc) is the more successful wine. It has a lovely golden colour, rich honeyed fruit with just a touch of oxidative evolution that adds to the complexity. Unlike a number of 2003 whites it has enough freshness and acidity in the finish to balance the rich fruit. We drank it as an aperitif but it would I’m sure be a great match with richly sauced fish dishes or grilled sea bass or similar. Along with a number of other Anjou producers this is further evidence that, despite the poor image of Anjou Blanc, it is certainly possible to make very fine whites here from 100% Chenin Blanc.

Christophe now makes two cuvées of Anjou Blanc – Ordovicien which is the equivalent of the above, spending 12 months in barriques and bottled around 18 months after the harvest – and Petit Princé, which is bottled earlier, around nine months.

New research shows that Cabernet Franc is not only one of the parents of Cabernet Sauvignon, it is also a parent of both Merlot and Carmenère. A group of French scientists working on grape DNA, in collaboration with Professor Carole Meredith, who was at UC Davis until she retired, have revealed that Merlot is a natural off-spring of Cabernet Franc and a previously unknown red grape named Magdeleine Noire des Charentes. Cabernet Franc teamed up with Sauvignon Blanc to produce Cabernet Sauvignon.

Further research by the group shows that Carmenère was parented by Cabernet Franc and a variety called Gros Cabernet, while the parents of the Loire’s Côt (known elsewhere as Malbec or Auxerrois, especially in Cahors) are Magdeleine Noire des Charentes again and Prunelard. The Black Magdeline was also a parent of the unknown grape Mourtès this time pairing up with another forgotten variety called Penouille.

The research was published in the Australian Journal of Grape and Wine Research on 22nd December 2008. The parental link between Carmenère and Merlot suggests a logic to the Chileans confusing Carmenère with Merlot.

Clearly fidelity and monogamy are not the norm in the grape world.


Here is the abstract for the article:

Background and aims: Based on parentage analysis of a large nuclear simple sequence repeat (SSR) marker database of grapevine genotypes, we propose the pedigree of several cultivars from southwestern France including Merlot, one of the world's major black winegrapes.

Methods and results: The putative mother of Merlot, deduced from inheritance at 55 nuclear and three chloroplast microsatellite loci, is a non-referenced and previously unknown cultivar, first sampled some years ago in northern Brittany where vines were cultivated at the end of the Middle Ages, and then identified in four places in Charentes. Considering both the name used by the growers of this grape and the literature, we have named it Magdeleine Noire des Charentes. The putative father of Merlot is Cabernet Franc, already involved in the parentage of Cabernet-Sauvignon. Further analysis of genetic relationships leads us to propose the kinship group of Merlot composed, among others, of Carmenère (Gros Cabernet × Cabernet Franc), Merlot Blanc (Merlot × Folle Blanche), Cot (Magdeleine Noire des Charentes × Prunelard) and Mourtès (Magdeleine Noire des Charentes × Penouille).

Conclusions: These results shed new light on the origin of Merlot and on the relationships among several cultivars from south western France.

Significance of the study: Our discovery of the key genetic role of a previously unknown cultivar in the origins of some significant cultivars reinforces the importance of deep exploration, before it is too late, to discover original genotypes which have not yet been collected or referenced.

2008 vendange: Catherine and other pickers

To the Clos Roche Blanche (AC Touraine) yesterday afternoon to taste the 2008s with Catherine Roussel and Didier Barouillet. As usual the welcoming committee – the dogs Margot and Pif – were already out as we arrived. Sécotine, the very friendly striped cat, and Pélagie, the wild black one, were also in attendance – Pélagie only briefly. Before tasting we chatted with Catherine and Didier, who was getting a consignment ready to go to the States. Around 50% of the Clos Roche Blanche’s production now goes to the States. Although with the current economic crisis, sales are dropping fast everywhere.

We talked about retirement – Catherine and Didier are cutting back from 18ha to 9ha, also about Joe Dressner and his amazing Captain Tumour Man blog. Apparently Joe is hoping to get over for the Salon des Vins de Loire at the beginning of February as his course of treatment will have finished by then. We also talked about the recent 4th edition of the Fête du Coin, featuring 20 vignerons, held this year at Chitenay over the weekend of 6th/7th December. Depsite la crise this edition attracted 700 visitors who bought a total of 6000 bottles.

We started the tasting of the 2008s with several Sauvignons at various stages of development with several still fermenting. The 2008 whites have high alcohols, which has made Didier’s winemaking job difficult along with the need to lower the high acidities of 2008. The still high levels of acidity at the end of September meant that alcohol levels were high by the time the grapes were ripe. One of the Sauvignon vats is at 14.5˚.

Didier tasting 2008 Pif and doubtless wondering
what proportion of the 2008 vintage this glass represents.

Didier: “Sugar levels on white grapes always go up more quickly than they do in red varieties.”

Of the four vats I tried I liked the first one best. It had finished its alcoholic fermentation but hadn’t been through malo. 13.8% alc and 5.5 acidity, it had very attractive grapefruit flavours – very precise. Didier explained the various methods he had used this year to reduce the high acidities. These included maceration carboniquee, 15 days of cold stablisation and allowing a ‘voile’ to develop on the surface of the Sauvignon, as they do in the Jura. I thought this might be the same as the flor that occurs in Jerez but apparently it is different.

Next up a lemony and quite weighty Chardonnay followed by a slightly fuller coloured than usual Pineau d’Aunis rosé, which still has some 10 gms of residual sugar.

Next onto the Gamay, which at 22 hl/ha, was the most generous yielding variety in the very small harvest of 2008. The 2008 Gamay has lovely spicy, black fruits and will be delicious. The second and last red was the rich, concentrated, deep coloured and spicy Pif – 50% Cabernet and 50% Côt. Sadly due to the penurious vintage there will be no Pineau d’Aunis Rouge, no pure Côt or Cabernet.

Before leaving Catherine lent me her signed copy of Alice Feiring’s The Battle for Wine and Love or How I saved the World from Pakerization, which I am now enjoying reading. Catherine also kindly gave me a bottle of Pascal Potaire’s Piège à filles pétillant naturel. (Both will doubtless be subjects for future postings on the blog.)
