One of Mathier's great ambassadors since the 2013 vintage and the no less successful counterpart to L'Ambassadeur de Diego Mathier red, the world champion Pinot Noir. The best winemaker of the decade also likes to refer to the white Ambassadeur as ‘the cool freshness of the mountains’, with a strict reduction in quantity of half a litre per m2 during the harvest.

Tasting notes for the 2020–2024 vintages

2024

A pale, bright yellow colour with greenish highlights. Still somewhat reserved on the nose, with notes of citrus fruits and white flowers. Vanilla and ageing notes still dominate slightly, but this lovely spring harmony will unfold once the wine has had the rest it deserves after bottling.

On the palate, it is fresh and taut. Lemon notes underline its youthful character. Juicy and fresh, this white Ambassadeur, vinified with great care, finishes with mineral and chalky notes, lovely length and plenty of tension, making it a perfect match for seafood.

Give it some time to recover from bottling.

2023

Bright and luminous colour. A very beautiful harmony on the nose with floral notes and a backdrop of exotic fruits. Barrique ageing with a very long maturation period at low temperatures perfectly highlights the freshness and crispness of the 2023 vintage, during which our vineyards in Tourtemagne delivered a perfect harvest with ideal health and an ideal sugar-acid balance.

This wine is intense on the palate, with tension and harmony. It is rounded off by a gentle note that pleasantly prolongs the enjoyment.

Perfect with grilled sea bass.

2022

A sunny vintage with a luminous colour, shimmering with a light straw-yellow hue. The bouquet is characterised by white-fleshed fruits and notes of mango. Ageing in barriques lends it complexity through delicate brioche notes. The attack is lush and powerful, with a long finish; the woody notes are distinctly present and add complexity. It reflects an opulent vintage in which all elements combine to form a subtle harmony. A wine to be enjoyed now, ideal with a cheese platter.

2021

The colour is light with straw-coloured highlights. As it matures, notes of dried apricots develop. The background is characterised by saffron notes and great complexity.

On the palate, it is full-bodied with ripe fruit, balanced by a refreshing salinity. Its aromatic finish is carried by citrus fruits and vanilla, derived from its ageing in wooden barrels.

A superb wine to enjoy time and again, perfect for sharing with a casserole of saffron scallops or a cheese platter.

2020

The colour is light with straw-coloured highlights. As it matures, notes of dried apricots develop. The background is characterised by saffron notes and great complexity.

On the palate, it is full-bodied with ripe fruit, balanced by a refreshing salinity. Its aromatic finish is carried by citrus and vanilla notes, derived from ageing in oak barrels. A magnificent wine to be enjoyed time and again, perfect for sharing with a casserole of saffron scallops or a cheese platter.

The juice from the destemmed and pressed grapes is matured on the lees in new barrique barrels for six months without being filtered. The wine is then blended and matured for a further ten months in the same oak barrels. After maturing for a total of 16 months in French oak barrels, the white L'Ambassadeur de Diego Mathier AOC has reached its perfect quality.

The three grape varieties Heida, Ermitage and Petite Arvine are cultivated on the very best slate-rich sites in Sion and Sierre as well as in elevated, clayey sites in Turtmann.
