An early adopter in Chablis, his grandfather took his time and ensured quality plantings were established around his village of Beines, earning the village its Chablis appellation recognition almost single handedly. In the 1960s the, now vast and established, family vineyards were passed down to the sons (father and uncle to Guillaume). 

From a young age Guillaume was among the vines and cellars with his father, learning the trade with a drive so strong that he began formulating his own ideas and styles for the family wines. Upon the passing of his father it became a lot more apparent that his vision was starkly different to that of his uncle’s, this was the moment Domaine 47°N3°E was born. Branching out on his own in 2018, taking his small share of family vines under his label, Guillaume began establishing his own cuvees in the vast Chablis region.

Keenly working year after year, he is exploring how each cuvée can obtain a fair balance between the typicity of the soils, the character of the grape variety and human intervention. The vineyards under his name represent just over one hectare of vines in total; 0.4 hectares of Chablis in Vau Brou and a 0.6 hectare block in the Premier Cru of Beauroy. Guillaume’s holding was planted in 1980 and sits just outside the town of Beines in the lieu-dit Côte de Savant, with an additional 2 hectares of Petit Chablis added more recently in 2020.

The vineyards are all proudly organically grown, with the whole process being of low-intervention winemaking. This practice stems from the internship Guillaume participated in with Nicolas Maillet in the Mâconnais, with the additional philosophies of respecting the terroir and vineyard over the process and the winemaker also instilling itself within the young producer’s mind. With this central to his own production, he opted to name his domaine after the place (his home town of Beines at 47°N3°E) and not his own name.

In the cellar, Guillaume crafts all his wines with native yeasts and aged without sulfur, though a small amount is always added at bottling. The Chablis is vinified and aged entirely in stainless steel tanks. He produces two Premier Cru wines from Beauroy and Côte de Savant with fruit for these cuvées coming from the exact same vineyard, which has the ability to be labelled as Beauroy or Côte de Savant. The difference lies in the ageing, with Beauroy aged in stainless steel, while the Côte de Savant fermented and aged in 500L oak demi-muids.

Clos Cachet is honoured to exclusively import Domaine 47°N3°E wines into Australia.
