Costigliole d'Asti, vineyards and hamlets between Asti and the Langhe
Barbera and moscato: in Costigliole d'Asti almost every hillside is planted with vines, and wine is what gives the place its character. The municipality lies south-west of Asti, on the road towards Alba and Canelli, and is one of the more populous in the province. The main village clusters around the castle on a hilltop, and around it spreads a large territory of hamlets and scattered houses among the rows of vines.
Buying here often means choosing a country house: brick farmsteads, barns to convert, and villas on the ridges looking over the vineyards. The roads are hilly, with bends and gradients, and some hamlets are a fair way from the services in the main village. If you work in Asti or Alba, a car is essential.
The slopes of the Asti hills, made of marl and sand, are prone to shallow landslides after long spells of rain. For a house on a slope or at the foot of a bank, the report shows the official landslide maps for the address; in the valley bottoms the flood maps are worth a look too.
In 2023 Istat, the national statistics office, counted 5,646 residents, down 5.4% on 2011. The estimated average age is 48.4, close to the province (47.9), and over-65s make up 28.0%. Foreign nationals account for 10.5%. Declared incomes are below the provincial average. For a municipality of this size, the public transport services recorded are fairly numerous, 0.53 per 1,000 residents against 0.13 in the province.
Earthquakes are a minor concern here. Costigliole is in seismic zone 4, the lowest in the Civil Protection Department's classification, like 112 other municipalities around Asti, with an expected acceleration of about 0.044 g. In older houses, what matters most is damp in the walls, the state of the roof and any cracks caused by ground movement. Cadastral maps from the Revenue Agency (Agenzia delle Entrate) cover the whole municipality, hamlets included.
