What makes a great Bordeaux vintage
A great Bordeaux vintage arises less from good weather than from a particular sequence: an even flowering in June, a summer that keeps the vines slightly dry without starving them, and an autumn that allows time until the grapes are truly ready. Evenness weighs more heavily than warmth, because only a vineyard that ripens together can be picked at the right moment at all.
Everything else is decided in the vineyard, in a chain of decisions that no one can correct afterwards.
Flowering has its say before summer begins
In June the vine flowers, and what happens in these few days lays itself over the whole vintage. Cool, damp weather during flowering means that some of the flowers set no berries at all — in viticulture this is called coulure — and that others grow into small, seedless berries next to normally developed ones, which is referred to as millerandage. At first this only looks like a smaller crop. The real consequence shows months later: berries at different stages of development sit side by side in one bunch, and there is no longer a day on which all of them are ripe at the same time. Anyone picking in such a year inevitably settles for a compromise or sorts by hand, several times and slowly.
What summer does with water
After colour change, the véraison, what helps the vine changes. A mild water deficit now slows shoot growth, the berries stay smaller, and colour and tannins in the skin become concentrated instead of diluted. If the shortage becomes too great, the effect tips over: the vine stops ripening and the grapes stall. In Bordeaux research the vine's water status is therefore regarded as a key factor for ripeness and vintage quality — and this is exactly where the weather ceases to mean the same for everyone. The same rain runs off gravelly subsoil and stays in a clayey subsoil. The soil mapping of our sixteen plots shows profiles that hold only around fifty millimetres of available water and others that store over a hundred and thirty. In a dry August, these are two different years on the same estate.
Autumn gives or takes time
In September and October it is then above all about time. Warm days and cool nights keep acidity and aromatics together and make it possible to wait for phenolic ripeness, the point at which the tannins in skin and seed have become soft enough. Rain shortly before the harvest takes this time away again: the berries absorb water, the must becomes thinner, and with the moisture the pressure from rot rises. Then picking starts earlier than planned. Whether a year is later regarded as great depends surprisingly often on these last weeks. That sugar and structure no longer automatically ripen together shifts this calculation further.
Why a vintage rating says little about a bottle
A vintage rating is an average. It sums up an entire region with very different soils and grape varieties and by its nature says nothing about what happened on an individual plot. Even within one estate the same summer turns out differently: our vines were planted between 1953 and 2025, they stand on clay, gravel, clay-gravel mixtures and sand, and they do not react in the same way to the same weather. A weak year on one plot can be a very good one on another, which is why the separate observation of each plot becomes useful in the first place.
How we read a vintage
Because this is so, we vinify plot by plot; only when kept separate does it become clear what a year has done with which plot. And because not every plot gives what it should every year, not every cuvée is made in every vintage at LaSuite aux Conseillans. The Allemande is a selection wine: in a year that does not provide its backbone, it is not made.
For the bottle on the shelf this has an unspectacular consequence. Because we only release a wine once it is ready to drink, nobody has to bet on a year they have not experienced. The question of what this vintage carried has then been answered by us, long before the bottle leaves the estate.
