Château des Rontets

Claire and Fabio Gazeau-Montrasi met while training as architects in Milan in the 1980s. Fabio's family had owned vines around Fuissé for generations, with the property at Les Rontets passing into the family through Fabio's parents. In 1995, after a decade of architectural practice in Italy, the couple decided to return to Fuissé and rebuild the estate as a quality-focused Pouilly-Fuissé operation. The transition was unusual: most Mâconnais quality-quality movement founders of the 1990s came from within the existing vigneron community, while the Gazeau-Montrasis arrived from a different professional discipline entirely. The architectural training has shown up in the way the estate is run, with deliberate attention to the renovation of the property's buildings (including the original eighteenth-century farmhouse) and an unusual visual sensibility around the wines' labeling and presentation.

The estate spans approximately six hectares of Chardonnay across the Fuissé and Vergisson communes. The home parcel at Les Rontets sits at mid-slope on Bajocian limestone with a south-east exposure. The Clos Varambon is the walled vineyard immediately adjacent to the property, planted in the early twentieth century and now carrying significant old-vine concentration. The Les Birbettes parcel sits at the foot of the Roche de Vergisson, with deeper Aalenian marls and a slightly cooler microclimate that produces wines with brighter acidity. Pierrefolle is a separate parcel on the Vergisson slope at higher elevation, with a thinner soil profile over limestone bedrock. The estate also farms a small Pinot Noir plot for limited red bottlings under Bourgogne and Mâcon-Fuissé Rouge labels.

The Rontets cellar approach is built around long élevage in older Burgundy barrels with minimal sulfur intervention. Yields are restricted to 30 to 40 hectolitres per hectare. Whole bunches are pressed slowly, with the juice settled briefly before transfer to barrel. Indigenous-yeast primary fermentations run slowly in 228-litre Burgundy barrels, with malolactic fermentation also taking place in barrel. New-oak proportions are deliberately kept low (typically under 15 percent), with most élevage occurring in older neutral barrels that contribute texture and slow oxygen exchange rather than oak character. Élevage runs twelve to eighteen months depending on cuvée; the Clos Varambon and Les Birbettes typically receive the longest aging. The wines are bottled with minimal filtration and low sulfur additions.

Rontets practices sustainable viticulture without pursuing organic or biodynamic certification. The estate works the vineyard with cover crops between rows, manual ploughing on the steeper parcels, and selective spray regimes that minimize copper and sulfur use. Vine ages run high across the estate: the Clos Varambon parcel carries vines planted in the early twentieth century, while the other parcels carry a mix of mature plantings from the 1960s onward. Replanting is done parcel by parcel with massale selection from the estate's own old vines, preserving the genetic character of the original plantings. Harvest is by hand with field sorting; the cellar work picks up the field selections without further intervention. The approach sits between the conventional Mâconnais viticultural mainstream and the certified-organic wing represented by Saumaize-Michelin and Goisot in the Grand Auxerrois.

Rontets is the contemporary Pouilly-Fuissé reference for what a small architect-vigneron operation can deliver. The Gazeau-Montrasi generation has built the estate into a benchmark over thirty vintages without expanding beyond the original six-hectare footprint; the discipline around scale has kept the parcel-by-parcel bottling structure coherent and the quality consistent. Clos Varambon, in particular, frequently rates among the highest-rated Pouilly-Fuissé village-tier bottlings in any given vintage, comparable to the apex bottlings of Ferret, Robert-Denogent, and Guffens-Heynen. The estate's success has been a reference point for the broader 2010s and 2020s movement of architects, designers, and other-discipline professionals into small Burgundian vigneron operations, and the Gazeau-Montrasi sensibility around presentation and aesthetics has carried into the visual language of the contemporary Mâconnais quality movement.
