Diolinoir red wine: a Swiss newcomer with character
The Diolinoir grape variety is a fascinating newcomer from Switzerland and impresses with its strong structure, intense colour and unique range of aromas. It was created in 1970 by crossing Rouge de Diolly (Robin Noir) and Pinot Noir. This grape variety was developed by André Jaquinet at the Agroscope research institute in Pully to create a rot-resistant and fertile red wine variety that thrives particularly well in Alpine climates. The Diolinoir grape variety places high demands on the vineyards and requires the winemaker to be committed to quality production.
Origin and crossing of the Diolinoir grape
The name Diolinoir is derived from the Rouge de Diolly mother vine, while the addition of ‘Noir’ emphasises the intense dark colour of the wine. The fertilisation of the Rouge de Diolly by the pollen of the Pinot Noir grape resulted in a robust grape variety characterised by excellent resistance to rot and fertility. Diolinoir is often used in blends with Pinot Noir and Gamay to further refine the characteristics of the grape. These characteristics make Diolinoir an important addition to the range of AOC Valais red wines.
Characteristics of the Diolinoir grape
The Diolinoir grapevine displays impressive resistance to disease and high yield stability. Despite its robustness, the vine requires a careful ripening process to fully develop its aromas and flavours. The grapes are medium-sized and have a thick skin, which contributes to the intense colour of the wine. The grape variety is also known for its deep, dark berry aromas and strong structure.
Taste and bouquet: a red wine with depth
The Diolinoir red wine is characterised by a subtle bouquet and remarkable complexity. The nose reveals aromas of dark berries, such as blackberry and blackcurrant, accompanied by delicate notes of spices and herbs. On the palate, the wine is powerful and harmonious, with well-integrated tannins and a pleasant freshness.
The combination of Pinot Noir and Rouge de Diolly gives this red wine a distinctive personality that makes it perfect on its own or with food.
The role of Diolinoir in the AOC Valais
The Valais region offers ideal conditions for growing Diolinoir grapes. Here, the vines benefit from intense sunshine, cool nights and mineral-rich soils. These factors contribute to the development of the complex aromas and strong structure of the wine. Within the AOC Valais, Diolinoir is considered one of the most exciting grape varieties with great potential.
Diolinoir and culinary delights
Thanks to its versatility, Diolinoir red wine goes well with a wide variety of dishes. Its strong structure and fruity aromas harmonise particularly well with:
- Grilled or braised meat, especially game or lamb.
- Hearty Swiss classics such as raclette and fondue.
- Aged cheese and rustic dishes with intense flavours.
The Diolinoir is also a convincing soloist thanks to its balance and depth, offering a unique taste experience.
Production and ageing of Diolinoir wine
Careful processing of the Diolinoir grapes is crucial for the quality of the wine. After the harvest, vinification begins, which aims to preserve the natural aromas and strong colour of the grapes. Some winemakers choose to age the wine in barriques to give it additional complexity and elegant woody notes.
The importance of Diolinoir for the Swiss wine world
Although the grape variety is relatively young, it has already become an established part of the Valais red wine range. Its resilience and ability to produce excellent wines under difficult conditions make it a valuable addition to Swiss viticulture.
Tasting tips for Diolinoir red wine
To fully enjoy the complex aromas and strong structure of Diolinoir, the wine should be lightly aerated and served at a temperature of 16 to 18 degrees. A short period of bottle ageing can further accentuate the notes of berries and spices.
Summary: a red wine with character
The Diolinoir red wine is an impressive representative of the Swiss wine world. With its intense colour, complex aromas and harmonious structure, it offers both wine lovers and novices an extraordinary taste experience. As a new variety with roots in the Valais region, it embodies the innovation and quality that characterise Swiss viticulture.
