Dei is a family-owned estate winery in the Montepulciano region of Tuscany, not far from the walls of Montepulciano itself, down a winding track (Rosemary George MW: 2004, p.193). The house, which was built by Marcello Piacentini in the 1930s is located in a park and has underground cellars. The main wines are Rosso di Montepulciano DOC, Vino Nobile di Montepulciano DOC, and Vin Santo di Montepulciano DOC.

Owner: Caterina Dei. She is the grand-daughter of the estate’s founder, Alibrando Dei. He had worked in the travertine business.

Background: In 1964, Alibrando Dei, a wine-growing enthusiast, bought some land [in Bossona, I think] as a holiday home but grapes from the existing vineyard were sold off until 1985 (Rosemary George, 2004, p.193). During the course of the 1970s, the family acquired the Martiena property at the foot of the village of Montepulciano, with its manor house (restored in the 1930s by the architect Piacentini), surrounded by a vast garden. In 1985 the family began making and bottling its own Vino Nobile di Montepulciano wine under the name ‘Dei’. They made the wine in an old winery they rented in the historic town centre. It was at this point that Caterina Dei’s father (who is in the marble business) persuaded her to join the estate. She was in the performing arts and has studied theatre and loves music. In 1989, the family built its own winery, beside Villa Martiena, in the heart of the vineyards and made its first wines on its own land. Caterina Dei’s first vintage was 1992 (a bad year).

Staff: Consultant oenologist: Paolo Caciorgna (previously Nicolò d’Afflitto). | Viticulturist: Jacopo Felici. 

Terroir: Production zones include Bossona, (Villa) Martiena, Località La Ciarliana, La Piaggia and Cervognano, in the northern sector of the Montepulciano zone.

Vineyards: 2018 101 hectares of land, of which 40ha of woodland and 61ha of vines. Focusing on Tuscan grapes when replanting, to replace French grapes (Merlot, Cabernet etc).

Viticulture: 2018 A mix of cover crops. All rows are sow with cover crops, not just alternate rows. Barley (Hordeum vulgare) or ‘orzo’ in Italian is a grass, sown for organic matter and soil structure. Fava beans (‘favino’), a legume, is sown for nitrogen (legume). Legumes are used especially on clay-rich soils. Mustard and rapeseed (Brassica napus or ‘colza), which are crucifers, are sown for soil decompaction. They are used especially on tufaceous or loamy soils which can be humid and thus provoke vine vigour. Source: Jacopo Felici (see above) (Anteprima, 2018).

Organic certification: 2018 Not yet.
