Château Guiraud, Sauternes, directly adjacent to Château d’Yquem.

A census taken on the estate in 2010 counted 635 species of insects, spiders and bees — more than three times what a Bordeaux vineyard typically carries. Biodiversity is a word almost every château now uses. This is one of the very few places that has counted it.

The work behind that number started long before the certificate. The estate began what its managers called a cultural revolution in 1996, stopped synthetic treatments that same year, and gave up insecticide entirely in 2004. Organic certification arrived only in 2011, fifteen years later — the first 1855 classified growth anywhere in Bordeaux to hold it, and the first in Sauternes.

Guiraud also keeps its own conservatory of Sémillon and Sauvignon Blanc clones, well over a hundred of them, maintained as a living genetic bank. Most estates plant whatever the nursery supplies, and commercial nurseries have narrowed the available material considerably.

Château Guiraud
Hedgerows, insect hotels and wild grass between the rows — biodiversity work begun in 1996.

When the owners decided to sell in 2006, the estate manager did not wait to find out who would buy it. Xavier Planty assembled a consortium — with Robert Peugeot, Olivier Bernard of Domaine de Chevalier and Stephan von Neipperg — and bought the château himself.

That is why the farming survived the sale. The person driving it became an owner, which is the only reliable way a long conversion outlives the manager who started it.

“For us organic is just the starting point.”

Why it’s remarkable

635
insect species counted on the estate
A census in 2010 recorded 635 different species of insects, spiders and bees at Guiraud — more than three times what is typically found on a Bordeaux vineyard. Biodiversity is usually asserted rather than counted. Here it was counted, and the number is the argument.
15 years
of work before the certificate arrived
The estate began what its managers called a cultural revolution in 1996, eliminated synthetic treatments that same year, and stopped using insecticide altogether in 2004. Certification came only in 2011 — the first 1855 classified growth in Bordeaux to earn it, and the first in Sauternes.
135+
clones held in the estate’s own conservatory
A living genetic bank of Sémillon and Sauvignon Blanc varieties, maintained to preserve diversity that commercial nurseries have narrowed. Most estates plant whatever clone the nursery supplies; this one keeps its own library.
Bought it
rather than let it be sold on
When the owners decided to sell in 2006, estate manager Xavier Planty assembled a consortium — with Robert Peugeot, Olivier Bernard of Domaine de Chevalier and Stephan von Neipperg — and bought the château himself. The farming philosophy survived the ownership change because the person driving it became an owner.

Blue cheese, foie gras, or a fruit tart.
