The Nizza DOCG classification is a fantastic example of what can happen when producers work together to promote their local territory. Located in the heart of [Piedmont](/region/piedmont), Nizza has long been considered one of the best areas of the [Barbera d'Asti](/appellation/barbera-dasti-docg) denomination due to its ability to produce concentrated wines that also offer freshness and aromatic complexity. This established belief has finally been recognised. For decades producers in Nizza have made reference to the sub-zone their wines come from. Making the link with their territory was a smart commercial move simply because so many in [Piedmont](/region/piedmont) knew the land produced better wines. . But what makes Nizza so special? Despite the inference that Nizza is a unanimous territory that was able to breakaway from the [Barbera d'Asti DOC](/appellation/barbera-dasti-docg) because of a common and well defined style is not quite true. The new Nizza production zone is made up of different soil types and as such offers a range of subtle variety across wines. The north of the area around the communes of Vinchio, Cortiglione, Incisa, Mombercelli and Mombaruzzo is largely sandy, while to the south, the area is made of of marl and sandstone. Marl soils usually produce wines that are a bit fuller with medium acidity with some decent shelf life. Sandy soils tend to give low intensity wines, with less structure and more acidity. They are more fragrant and elegant, but with lower alcohol and are ready to drink earlier.
