The Jura vineyard occupies a natural region known as the Revermont, bounded to the east by the first limestone plateau at an average elevation of 550 metres and to the west by the plain, which forms the eastern edge of the Bresse graben.
The vineyard extends over approximately 80 kilometres from north to south, but is only a few kilometres wide along the east–west axis, with a general west-facing exposure.
The vines are planted on hillsides composed of marls and marly limestones, overlaid with abundant stones derived from the fragmentation of the hard rock strata above.
These steep slopes, often well exposed, are sheltered from the north wind by the wooded summits of the hills separating the limestone plateau from the Bresse plain.
The climate is semi-continental, with a wide temperature range between winter and summer, warm and humid summers — the Revermont receiving significantly more rainfall than the neighbouring plain — and an autumn that is generally sunny, dry, and windy.
