1855 second growth Gruaud-Larose is very much one of the grander estates in Saint-Julien. It occupies a high point on the Medoc plateau and I can attest it gets windy there; that wind serves to dry the vines and help prevent vine infections. The modernistic viewing tower that divides opinion and stands in angular contrast to the classical chateau does enjoy some far-reaching views of the Medoc.

At one of Pauillac’s highest spots, with plots next to Latour (overlooking the Gironde) and to Pichon-Baron (on the Bages plateau), Haut-Bages Liberal has always enjoyed great terroir. But even that is not enough to explain the quality of recent vintages here. Jane Anson calls owner Claire Villars ‘one of the most exciting winemakers in Bordeaux’, and the work that Claire has been doing here is remarkable. She has completely transitioned the estate to biodynamic viticulture.

There are a few things that make Haut-Bailly special. There`s the fact that nearly 15% of the vines are still prephylloxera, that it is one of the few Pessac-Leognan properties not to make white wine, that it has soil that actually contributes to that rare thing in Bordeaux - real sense of terroir. That soil is sandy seabed stuffed with shellfish fossils. As a property it is less than 150 years old and like many Bordeaux estates has seen its fair share of ups, downs and idiosyncratic owners.

In 1942, the Batailley estate was divided into two, so that two brothers could each have their own part. One half continued under the name Batailley, and the other (smaller) part was re-christened Haut-Batailley. Like Batailley itself, Haut-Batailley is a fifth growth under the terms of the 1855 classification, as a continuation of an 1855 classified estate. For decades, it was ably managed (but not owned) by Francois-Xavier Borie (who owns Grand-Puy-Lacoste), and in 2006 he began a huge renovation of the wine-making facilities and cellars.

This property dates back to the fifteenth century, though the earliest mention in English is the celebrated entry in Pepys` diary in 1663 to Chateau Haut-Brion`s wine bar in the City of London. It is now the only Bordeaux chateau to be owned by Euro-aristos, with the holding company being controlled by Prince Robert of Luxembourg, or Bobby deluxe as he`s known in the trade. Haut-Brion is the only Pessac/Graves chateau to be mentioned in the 1855 Medoc classification as well as its local one.

In the 1855 classification of the Medoc, one wine that was not from the Medoc but rather Pessac was also admitted; Haut -Brion. Its Pessac neighbour La Mission Haut-Brion was not granted a similar special admission. Yet if any wine from Pessac also deserves first growth status, it is La Mission Haut-Brion.

The land that the Labegorce estate now sits on entered recorded history when a certain Duke William of Acquitaine made it his own. The Duke had no known achievements in winemaking but is remembered as an early troubadour and for leading an army in the 1101 ‘Crusade of the Faint-Hearted’, which didn’t go at all well. Vines arrived in the 17th century, and in the 18th century the name Labegorce arrived as a corruption of L’Abbe Gorce, ‘Abbot Gorce’, the Abbot in question being an owner for a while. When the Revolution arrived, the Labegorce estate was large and successful.

Austere and evasive in youth but deeply profound in age, Lafite is one of the five Medoc First Growths, and one of the two owned by branches of the Rothschild family. It is one of the oldest estates in Bordeaux - the ‘Seigneurie de la Hite’ domaine is noted on a document from 1234, though in those days it was all about cereal and cattle. Vineyards were not seriously laid out here until the 1680s, at the hands of Jacques de Segur, who laid out what would become many of Bordeaux’s great vineyards.

Few Bordeaux chateaux are more associated with a particular colour than St-Estephe fourth growth Lafon-Rochet; both the chateau itself and the label on the bottle are a bright shade of yellow. (It’s worth noting, though, that over in Pomerol Vieux Chateau Certan does own pink). Lafon-Rochet began as an aristocratic home and estate, though (unlike many chateaux) it was not confiscated during the Revolution. The modern world arrived in 1959, when chateau and estate were purchased by the Tesseron family.

No Bordeaux classed growth has been in the hands of the same family longer than Langoa Barton; it was purchased by Thomas Barton in 1821. Of course, Leoville Barton followed into the family stable soon after, and both properties are now on their eighth generation of Bartons, with Damien Barton now working beside his sister Melanie and their mother Lilian. The two properties are inevitably defined against each other. The Leoville Barton vineyards lie in the north of St-Julien, between the chateau and the river.

In my tiny mind Chateau Latour always seems the most stolid of the first growths, the most reliable, the one you would want on your side. Yet in recent times their radical decision to abandon the en primeur system went against current thinking and they remain alone in this. Although the estate was founded in the 15th century, the wine entreprise started around 1670. Within 50 years, Latour was building a reputation for quality and there was already over 35 hectares of vines.

One might expect the three Leoville siblings - Leoville-Poyferre, Leoville-Las Cases and Leoville-Barton - to make broadly similar wines. After all, they are neighbouring estates, all in St Julien, all classified as second growths in 1855, and all once part of the very same estate, Leoville, until debt and Napoleonic-era turbulence sundered them. But with different owners and winemakers at each, they can produce radically different wines.

The commune of St Julien may have no first-growths, but it is well served by seconds and fourths (Margaux rules the thirds). Perhaps the most high profile of all St Juliens is `super second` Leoville Barton, consistently producing brilliant, structured wine that barely falls short of the first growths, and for a fraction of the money.

The Leoville plateau has long been recognised as one of the best spots in Bordeaux for producing long-lived, complex, powerful wines. Once upon a time, it was a unitary estate, for a while owned by the Marquis de Las Cases. Then came the revolution, and the estate was seized, and split into three parts, later identified as Las Cases, Barton and Poyferre. Las Cases has the heart of the old estate, the Grand Clos, which sits on gravel soils up to ten metres deep.
