La Marca di San Michele is an organic estate in the Jesi area of Ancona province of the Le Marche region, Italy. La Marca’s focus is on white wines: Verdicchio dei Castelli di Jesi DOCCastelli di Jesi Verdicchio DOC Classico Superiore, anCastelli di Jesi Verdicchio DOCG Riserva. The winery and vineyards are in Cupramontana which is the historical birthplace of Verdicchio production in Le Marche.

Background: In 2007 Alessandro Bonci, Beatrice Bonci, and Daniela Quaresima swopped their city-based lives (different professions) for organic farming and wine making. They took over the 6ha vineyard owned by Alessandro and Beatrice’s father, Pietro. The estate was initially purchased by their grandfather Fernando Bonci, and Fernando’s brother Mario (they called it Valle Rosa). Fernando’s mother bought what is now the estate, using her widow’s pension. She had 4 children, one of whom was Pietro. The estate has remained more or less as it was originally. The impulse to work with rather than against nature came from the new generation, who with Ampelio Bucci, was among the first producers in the Marche to join the independent winegrower group, FIVI. On 10 January 2019 Beatrice left the business.

The estate: 2019 6ha of vines, 2ha of olives, 2ha of field-sown crops (eg barley, durum wheat) which are sold to an organic co-operative.

Vineyards: 6ha of which 5ha of Verdicchio and 1ha of Montepulciano. The vines are in San Michele, around the house, with a view to Staffolo opposite. One can see the Adriatic sea from here (and from Cupramontana) on a clear day. The altitude is 300-400 metres above sea level. The soil is calcareous clay marl, a 12 million year old former seabed, on slopes climbing the foothills of the Apennine mountains facing east towards the Adriatic sea. San Michele is an early ripening area, upto 14-21 days earlier than other areas. The main plots are Vigneto Grande, Vigneto Piccolo (Verdicchio used for Capovolto, a Classico Superiore), and La Querce (Verdicchio used for Passolento Riserva wine). 

Biodynamics: 2018 Horn manure 500 and Horn silica 501 were sprayed here for the first time. See Biodynamics.

Certification: 2007 Bio sans papiers. | 2009 Conversion to certified organic status begins. | 2012 First vintage with full organic certification.

Winemaking, wine style: Alessandro told me he looks for four things in a wine: saltiness from the terroir, ripeness from the climate, flavour from the grape variety, and mouthfeel from the pH (acid strength) and the acid(s) itself. He makes two different wild yeast starter cultures, one for sparkling wine and the other for still wine, and the press is cleaned between a load of grapes destined for sparkling wine and grapes destined for still wines, despite both being Verdicchio.

Labels: Each wine has a minimalist cadastral (‘catasto’) map on its label showing where the grapes came from.

Sparkling wines

Traditional method sparkling (‘spumante’) wine with a second fermentation in bottle but without either disgorging or dosage. | 2011 Numero Zero. First vintage. 800 bottles. Classic method sparkling wine with no dosage (‘Dosaggio Zero’). Made with Liana Peruzzi. | 2014 Numero Uno 100% Verdicchio. Wet vintage. 2,500 bottles. | 2016 Numero Due Col Fondo Picked early. Tried freezing some juice to provoke the second fermentation in bottle but in the end had to use purchased organic yeasts for the second fermentation in bottle. 12.5% alc. 0g/l residual sugar. 2,500 bottles. | 2017 Hot vintage. None made. | 2018 2,500 bottles. | 2019 Due to be picked early. Pressed. Juice fermented to dryness with around 11.5% alc. Kept on fine lees in tank until May (2020). Add unfermented juice and yeast to provoke second fermentation, using a closed circuit to pump and thus mix the existing wine, the yeast and the sugar – in the form of the unfermented juice, which will add an extra 1% alcohol to the wine (leaving it with 12.5% overall). On the same day as mixing the wine-juice mix is bottled (so both lees and fresh sugars are in suspension) with the bottles sealed with a cork and cage. The wine is left to age for three years.
