Chenin blanc

Chenin blanc (known also as Pineau de la Loire among other names) is a white wine grape variety from the Loire Valley of France. Its high acidity means it can be used to make varieties from sparkling wines to well-balanced dessert wines, although it can produce very bland, neutral wines if the vine's natural vigor is not controlled. Outside the Loire, it is found in most of the New World wine regions; it is the most widely planted variety in South Africa, where it was historically also known as Steen. The grape may have been one of the first to be grown in South Africa by Jan van Riebeeck in 1655, or it may have come to that country with Huguenots fleeing France after the revocation of the Edict of Nantes in 1685. Chenin blanc was often misidentified in Australia, as well, so tracing its early history in the country is not easy. It may have been introduced in James Busby's collection of 1832, but C. Waterhouse was growing Steen at Highercombe in Houghton, South Australia, by 1862. It provides a fairly neutral palate for the expression of terroir, vintage variation, and the winemaker's treatment. In cool areas, the juice is sweet but high in acid with a full-bodied, fruity palate. In the unreliable summers of northern France, the acidity of under-ripened grapes was often masked with chaptalization with unsatisfactory results, whereas now, the less-ripend grapes are made into popular sparkling wines such as Crémant de Loire. The white wines of the Anjou AOC are a popular expression of Chenin as a dry wine, with flavors of quince and apples. In nearby Vouvray AOC, vintners aim for an off-dry style, developing honey and floral characteristics with age. In the best vintages, the grapes can be left on the vines to develop noble rot, producing an intense, viscous dessert wine, which may improve considerably with age. French ampelographer Pierre Galet has theorized that Chenin blanc originated in the Anjou wine region sometime in the 9th century, and from there traveled to Touraine by at least the 15th century.

Logements collectifs et jardins familiaux: densification urbaine à Neuchâtel

Aziz Temel

Par l'histoire de Neuchâtel, nous apprenons qu'au XVIIIe siècle la ville était pourvue d'un espace vert nommé “Jardin Desor”. La présence de calcaires, vestiges des rivages anciens, avait permis à ceux-ci d'être joliment aménagés en sculptures minérales durant les siècles passés. Situé à l'entrée Est de la ville, il offrait un cadre idyllique aux citadins en quête de nature à vivre. Quelques décennies plus tard, l'urbanisation croissante a provoqué la disparition de ce jardin qui se trouvait sur l'actuelle pointe du site de la Maladière. Au fur et à mesure, ce dernier s'est vu approprier par la construction d'immeubles se jouxtant les uns aux autres, sans pour autant réinvestir la “nature” du lieu-même. Alors qu'elle avait été traitée avec sensibilité et poésie, elle se manifeste actuellement par un dénivelé mal absorbé et représente une blessure pour tout un quartier. A travers le thème des jardins familiaux et ses usages, comme élément de compréhension globale d'une ville et de sa nature urbaine, il s'agit ici de concevoir un nouveau morceau de ville pour des familles désireuses de trouver une nouvelle conception du “vivre ensemble”. Par une hybridation du végétal et du bâti, allant de l'espace public de la ville jusqu'à l'espace privé du logement, le projet tente de concilier densité urbaine et qualité de vie, afin de nous conter une nouvelle histoire: celle de la “nature” d'un sol et de ses strates successives.
