Humagne Blanche

Humagne Blanche has one of the longest documented histories of any Swiss grape variety. Its first written record dates to 1313 in the register of Anniviers in the Valais canton. The variety was widely planted through the 19th century before nearly disappearing in the early 20th century, likely displaced by higher-yielding and more disease-resistant varieties. A revival effort has brought it back to modest but growing cultivation. Ancestors Colombaud and Chichaud trace its lineage to southern France, and 2007 DNA profiling confirmed the variety is genetically identical to Miousat, a French variety known under the alternate names Miousap and Mioussat.

• First documented in 1313, making it one of Switzerland's oldest recorded grape varieties
• Nearly extinct by the early 20th century, now undergoing a measured revival
• Ancestors Colombaud and Chichaud originate from southern France
• DNA profiling in 2007 confirmed genetic identity with French Miousat

Humagne Blanche is an indigenous autochthonous variety confined exclusively to the Valais canton in Switzerland. Total plantings cover just 26 hectares, making it one of the rarest commercially produced wine grapes in Europe. Vines grow in alpine foothills at high altitudes on chalky scree and limestone soils, benefiting from the dramatic diurnal temperature shifts characteristic of the alpine climate. The Leytron sub-region within Valais AOC holds Grand Cru eligibility for wines produced from this variety.

• Plantings limited to 26 hectares, entirely within Valais canton
• Grown on chalky scree and limestone soils at alpine foothills
• Dramatic diurnal temperature shifts help retain acidity and develop aromatics
• Grand Cru eligible in the Leytron sub-region of Valais AOC

Humagne Blanche produces dry, full-bodied white wines with a delicate and elegant character. The aromatic profile centres on lime blossom, orange blossom, vineyard peach, and hazelnuts. With age, resinous notes develop alongside the variety's persistent mineral character. Good natural acidity gives the wines structure and supports an aging potential of five to seven years. The combination of floral lift and stony minerality is a direct reflection of the alpine limestone terroir.

• Aromas of lime blossom, orange blossom, vineyard peach, and hazelnuts
• Full-bodied yet delicate, with strong mineral character from limestone soils
• Develops resinous notes with bottle age
• Aging potential of 5 to 7 years supported by good natural acidity

Growing Humagne Blanche requires commitment. The variety is susceptible to powdery mildew and rot, demanding attentive canopy management in the often humid alpine environment. Yields are low, which concentrates flavor but limits commercial viability and has historically made growers reluctant to plant it. The variety also earned a cultural footnote around 1815 when it became known as 'wine for new mothers,' a tradition rooted in the belief, now unverified scientifically, that the wine contained elevated iron levels.

• Susceptible to powdery mildew and rot, requiring careful vineyard management
• Low yields limit commercial appeal but concentrate flavor and character
• Historically prescribed to new mothers around 1815 for presumed iron content
• Parent variety to Himbertscha and Lafnetscha, two other rare Valais grapes
