Léon Millot
Also known as: Kuhlmann 194-2
Léon Millot
Summary
Léon Millot is a French-American hybrid developed by Eugène Kuhlmann in Alsace in the early 20th century, prized for its extreme cold hardiness, early ripening, and ability to produce quality red wines in marginal climates. Sister variety to Maréchal Foch, Léon Millot is often considered the softer, more elegant of the two. With plantings across the northeastern United States, Canada, United Kingdom, and Scandinavia, Léon Millot has proven invaluable for viticulture in regions where most vinifera varieties cannot survive, producing wines that range from light Pinot-like styles to deeper, more structured reds.
Identity
VIVC: Entry #6907
Berry Color: NOIR
Type: French-American hybrid
Breeding Number: Kuhlmann 194-2
Creator: Eugène Kuhlmann, Alsace, France
Year: Early 20th century
Name Origin: Named after Léon Millot, likely a colleague or patron of the breeder.
Genetic Origin
Parentage: Millardet et de Grasset 101-14 × Goldreisling
Breaking down the parentage:
- Millardet et de Grasset 101-14: American vine hybrid (Vitis riparia × V. rupestris); provides cold hardiness and disease resistance
- Goldreisling: German vinifera variety (Riesling × Courtiller musqué); provides wine quality
Related Variety: Maréchal Foch is a sibling (same cross)
Character Difference: Léon Millot generally produces softer, more elegant wines than the firmer, more tannic Maréchal Foch
