Chateau Closiot

Bordeaux

The eight hectare Bordeaux estate of Jean-Marie Guffens of Guffens-Heynen has parcels of century-old vines on the enviable Clos Bonneau, where the soils are red clay with classic left-bank pebbles atop. Planted mostly to Semillon, there is also Sauvignon Gris and Sauvignon Blanc. Counting Climens, Doisy-Védrines and Coutet among its neighbors, this is a Chateau to watch, with Guffens' association not the least important reason.

J.M. Guffens' Notes on the 2025 Vintage:

"At Closiot, the news is significant because Philo and I have decided to take over the Barsac appellation vineyards of our neighbor, Château Piada. Eight hectares of old vines, which will double our acreage. A bold gamble on the future, one in which I firmly believe. I've fallen in love with this exceptional terroir, which can produce both the most sublime sweet wines and outstanding dry wines. Although the acreage has doubled, the quantity harvested in 2025 will remain the same as in previous years. Indeed, the yields were negligible: 18 hl/ha for dry wine and 7 hl/ha for Barsac."

The Barsac (Left-Bank Bordeaux) Chateau of Jean-Marie Guffens, an extension of his Maconnais empire, Chateau Closiot is producing world-class dry and sweet wines possessing the finesse and depth for which Guffens has earned acclaim.

THE VINEYARD Sourced from all the Chateau's vineyards as there were no sweet wines made in 2023.

VINE AGE Average of 50 years of age

THE BLEND 85% Semillon 15% Sauvignon Gris

FERMENTATION Vinified entirely in cask, 25% of which are new.

WINEMAKER'S NOTES "Due to the high temperatures, there was little botrytis and a lot of acetate. So I decided to harvest three times in the space of three weeks. The blend gives a "C de Sec", aged 100% in barrels, extremely rich, exotic as desired and with an extraordinary length. A real dry Sauternes, or rather Barsac, because the limestone gave a lot of minerality to this wine."

A full-bodied expression of Bordeaux Blanc, focusing on the nutty and toasty expression of the Semillon grape.

WINEMAKER'S NOTES The Barsacs are majestic and this vintage will be a landmark in Sauternais where we had to wait a long time. This wait paid off. The Barsac “Bonneau” is similar to the 2018 with a little extra freshness"
