Domaine Pierre Gonon – The Benchmark for Saint-Joseph from Mauves
Domaine Pierre Gonon is the benchmark address of the Saint-Joseph appellation in the northern Rhône and is regarded by many critics as the standard-bearer for classically made Syrah and Marsanne-Roussanne from this region. Its headquarters and cellar are in Mauves (Ardèche), on the right bank of the Rhône opposite the Hermitage hill. The fourth-generation family estate comprises around 10 hectares, spread across roughly 40 parcels within the three communes of the historic AOC core: Mauves, Tournon-sur-Rhône and Saint-Jean-de-Muzols. Essentially only two wines are produced, a red and a white, both under the name Les Oliviers — a testament to their focus on what matters most. The domaine is today run by brothers Jean and Pierre Gonon and is certified organic.
Stylistically, Gonon stands for precise, naturally made wines that uphold all the virtues of the appellation system: pure, healthy fruit, correct tannin structure and a calm, slow evolution.
Founding and Ownership
The roots go back over four generations. The great-grandfather grew vines and sold his wine to a single bistro in Valence — around 30 barrels a year. Grandfather Émile worked in the office of the Mairie, as there was too little vineyard land left to make a living from it. It was only father Pierre Gonon who got the estate going again in the 1950s: he was forward-thinking in his commitment to white wine and planted the first Marsanne in 1958; the domaine’s first estate bottling was the 1964 Blanc — a remarkable event at the time.
Father Pierre fell ill in 1989 and handed the domaine to his sons early. Jean has worked at the estate since 1986, Pierre since 1988. Together they have led the domaine into the top tier. A new cellar was completed in 2002, so that all the wine is now made under one roof — a postmodern entrance façade, with the traditional old cellar behind it.
Philosophy and Style
The domaine’s motto amounts to “Simple is best”. Deliberately, only one white and one red are produced, both called “Les Oliviers”. The brothers work exclusively with indigenous yeasts — a generational matter, as Jean Gonon notes: winemakers in their forties tend to be more inclined to inoculate their vats, younger ones less so. “The main problem with foreign yeasts is how much they make so many wines bland and similar,” says Jean. Inoculation was only used in 1984 and 1992 — tellingly, in tricky vintages.
All vineyard work is done by hand: from massal selection using the estate’s own vine material, to tying and training the vines on wooden stakes (no wire trellising), through to shoot-thinning. The brothers also observe the lunar cycle for pruning and only begin in mid-January — contrary to the early pruning in November now widespread.
Vineyards, Sites and Terroir
The roughly 10 hectares are spread across some 40 parcels within three communes — unusual for a Saint-Joseph domaine, since most estates draw from only one commune. “It’s a good spread of soils and expositions,” says Jean Gonon.
The white-wine site Les Oliviers lies above Tournon at around 200 metres of altitude and was already known as a top site before the AOC was founded in 1956; its wine was then sold as “Vin des Oliviers”. The soil contains old Rhône stones and red clay with only a little sandy granite — it yields fuller-bodied white wines with low acidity and good ageing potential. The two hectares of white varieties (80% Marsanne with a core planted in 1958, 20% Roussanne with a core planted in 1974) are on average around 30 years old.
The red wine comes from around eight hectares of Syrah, spread across Tournon, Saint-Jean-de-Muzols (including plantings on the Aubert hill) and Mauves. Alongside Les Oliviers and Aubert, key sites include Montagnon, Martinot, Côtes des Rivoires and Croix de Peygros. The highest site in Tournon, at 308 metres, produces markedly red-berried fruit and good structure; the vines around 100 metres lower ripen earlier and yield a juicier, rounder character.
Grape Varieties and Cuvées
- Saint-Joseph Blanc “Les Oliviers” – around 80% Marsanne, 20% Roussanne
- Saint-Joseph Rouge – Syrah
- Saint-Joseph Rouge “Les Oliviers” – Syrah
- Vin de France “Les Iles Feray” – a fruity, lively Syrah, given the same treatment as the red Saint-Joseph
- Vin de France Chasselas – a rarity from an old variety
Vinification and Cellar Work
The red wine is picked as late as possible and made in traditional fashion: fermentation in open wooden vats, exclusively with wild yeast, twice-daily punch-downs over two to three weeks, with a daily pump-over at the start. The wine is left extended on lees even after malolactic fermentation. Ageing takes 13 to 15 months in 600-litre barrels, supplemented in generous vintages by a 12-hl foudre, with two bottlings between November and June. The wood can be anywhere from one to 40 years old. The red wine is not filtered, but may be fined.
The white wine, after pressing and fermentation, is aged on lees in used Burgundy barrels (three to 15 years old), with weekly bâtonnage until the first warmth of May, then left undisturbed until August and bottled around the following harvest.
Style and Flavour Profile
The red Saint-Joseph is always a wine of class that takes its time to open up. Young, it appears reserved, yet the fruit quality is always pure and healthy, the tannin presence correct — it evolves calmly and slowly.
The white Les Oliviers is highly accomplished: the Marsanne from the 1950s plantings delivers a satisfying persistence of flavour and a fine, oily texture; the Roussanne from the 1970s is livelier, less rich, but more complex, with hidden dry facets. The two complement each other superbly. These are outstanding food wines — with white meat, sweetbreads in a mushroom-cream sauce, even with spiced dishes.
Ageing Potential
Gonon’s white wines live exceptionally long. Both white and red have an ageing potential of several decades.
Accolades and Critical Acclaim
Gonon is today unquestionably regarded as the benchmark address for Saint-Joseph. The wines are regularly rated at the highest level by Decanter, Jancis Robinson, Vinous and leading importers (Kermit Lynch, Berry Bros. & Rudd), and as sought-after rarities they are usually sold out quickly.
Market Prices and Buying Guidance
Owing to the small production and high demand, Gonon’s wines are sought-after collector’s items:
- Saint-Joseph “Les Oliviers” (red and white): usually in the mid to upper double-digit euro range, sometimes higher depending on vintage and source
- Les Iles Feray (Syrah Vin de France): a more accessible entry point in the low to mid double-digit range
For an introduction to the Gonon style, the Les Iles Feray is a good choice; those wanting to experience the domaine’s full class should reach for the red or white Les Oliviers and give it a few years to mature.
