Terroir

• The geographical area extends over a rolling plateau corresponding geologically to the primary formations of the foothills of the Armorican Massif and to the more recent formations of the Secondary and Tertiary eras of the Paris Basin.
• The geographical area runs along the Loire and its tributaries, the Vienne, the Indre and the Cher, for approximately 200 kilometres and, in 2023, extends over the territory of 246 communes.
• The plots have schistous or clay-schist soils to the west and clay-limestone soils (Cenomanian, Turonian, Senonian and Eocene) to the east, all with moderate available water reserves and good drainage capacity.
• The Turonian geological stage gave rise to tuffeau stone, whose extraction through numerous quarries left cavities converted into cellars with constant temperature and humidity, dedicated to wine storage.
• The climate is oceanic with nuances: the eastern fringe, corresponding to the viticultural Sologne, experiences a more continental influence with annual rainfall of between 550 and 650 millimetres, while the Loire's hydrographic network and its tributaries play a thermal-regulating role.

• Saint Gregory of Tours mentions, in the 6th century, in his History of France, an extensive cultivation of the vine and the use of "traquettes" to scare off birds when the grapes ripen.
• From 1811 Jean-Baptiste Ackerman developed the production of sparkling wines using the traditional method, and the cavities dug out for tuffeau extraction became favoured sites for winemaking.
• The Crémant de Loire appellation d'origine contrôlée was recognised by decree of 17 October 1975, with production rules requiring manual harvesting, whole grapes at the press, gentle pressing and extended ageing on laths.

• The wine shows a steady effervescence made up of strings of fine, delicate and persistent bubbles, whether white or rosé.
• The nose often evokes aromas of white flowers mingled with fruity notes such as peach or apricot, while the palate combines freshness with sweetness.

• The presence of cellars dug into the tuffeau has been a favourable factor in the development of these wines' production, which requires vast temperature-controlled spaces for storage and handling.
• The mesoclimatic variations and diverse soil conditions within the geographical area have allowed producers to match grape variety plantings to their respective characteristics.
