Vallée d'Aoste Jambon de Bosses
Saint-Rhemy-en-Bosses, Valle d'Aosta, Italy
Aromatic and herb-scented, with a deep, savoury lean and a distinctive note of Alpine hay and juniper.
Overview
Jambon de Bosses is a high-Alpine ham matured around 1,600 metres near the Great St Bernard Pass. Salt, juniper, thyme, sage and mountain aromatics give the ham a more herbal character than the plain hams of the Po valley, while cold dry air supports a very long cure.
Where it's from
Climate. Saint-Rhemy-en-Bosses high in the Aosta Valley, thin, cold Alpine air.
Altitude. High Alps, around 1600 m
The cut

How to recognise it
The whole ham is compact and often slightly irregular, with a dark seasoned exterior. The slice is wine-red to dark red with firm white fat and a pronounced but elegant aroma of juniper, thyme and mountain herbs. It should be compact yet tender. Mustiness, damp hay odour, rancid fat, sourness or a sticky bone area are defects.

Origins and history
Saint-Rhémy-en-Bosses stood on one of the principal routes across the western Alps. Travellers, merchants, pilgrims and soldiers moved through the Great St Bernard Pass, and the hospice accounts provide a rare documentary anchor: in 1397 they mention tybias porci, pig legs produced in the area. A durable ham was valuable both to local households and to people crossing the mountains. The craft survived in a small community whose altitude, dry air and winter cold made long ageing possible. Herbs gathered from the valley became part of the local flavour, and some traditions include maturation on hay. PDO protection in 1996 recognised an unusually precise relationship between one Alpine municipality, its pass culture and a seasoned whole ham.
Name. Jambon is French for ham, reflecting the bilingual Valle d'Aosta; Bosses names the hamlet where it is made.

Serving and cultural significance
Slice thinly and serve with rye bread, butter, chestnuts, honey, Fontina and Alpine wine. A small plate with pickled vegetables or apples also works well. The herb profile is already complex, so simple accompaniments show the ham best and allow the juniper and thyme to remain clear.

Traditional or protected production
PDO production takes place in Saint-Rhémy-en-Bosses. Selected pork legs are trimmed, dry salted and seasoned with the protected mountain spice profile, then matured in the high-altitude climate for the required period. Traditional operations may include boning, tying and contact with hay according to the specification and producer practice.
