Pierre Gonon represents a multi-generational Saint-Joseph family enterprise on the steep, granitic right-bank terraces of the northern Rhône. The Gonon family has long championed organic and biodynamic viticulture, working their vines with minimal chemical input and deep seasonal attention. Les Iles Feray is a single-vineyard selection from mature vines planted on decomposed granite (schist), lending mineral linearity to the wine. The 2017 vintage in the Saint-Joseph appellation saw a warm spring leading to early bud-break, a dry summer with moderate heat spikes, and an extended, cool-finish ripening phase. These conditions preserved acidity while allowing phenolic development, ideal for the appellation's fresh yet structured Syrah style.

Hand-harvested grapes underwent partial destemming, retaining some stems to enhance natural tannin structure. The fruit fermented naturally with native yeasts in concrete and neutral oak vessels, a traditional approach that emphasises terroir expression over winemaking intervention. A prolonged post-fermentation maceration (typically 2–3 weeks) drew additional complexity from the skins. The wine was aged in neutral oak and large-format foudre for approximately 12–14 months, allowing maturation without new-oak tannin overlay. Minimal sulphur addition preserved the wine's delicate phenolic character.
