Foillard's vineyard parcels in Morgon occupy ancient volcanic soils derived from porphyry and granite bedrock, with clay-rich subsoils on south and southeast-facing slopes between 400 and 500 metres elevation. The house has farmed organically since the 1990s, practising natural vinification with minimal external inputs and respecting indigenous microbial populations. Morgon's 2009 vintage saw warm, dry summer conditions following a cool spring, extending the growing season and deepening phenolic maturity in Gamay berries. Yields were kept moderate through careful cluster thinning, concentrating fruit flavours and tannin development.

Foillard employs semi-carbonic maceration for Cuvée 3.14, retaining whole bunches to amplify aromatic complexity and preserve delicate fruit-derived tannins. A period of whole-grape fermentation precedes traditional foot-treading and gravitational transfer without mechanical intervention or enzyme additions. The wine rests in neutral concrete or glass vessels to preserve varietal expression; minimal sulphur additions at bottling underscore the house's low-intervention philosophy. Long maceration, typically three to four weeks, gradually builds tannic structure and colour whilst avoiding extractive oak influence or oxidative character.
