Quintal d'Alsace Cabbage Seeds Vilmorin - Large Flat Heads for Sauerkraut

Quintal d'Alsace Cabbage Seed Packet Vilmorin (Reference: 3304441) represents the very best of traditional French vegetable seed. This ancestral variety, selected by the Vilmorin master seedsmen, embodies the robustness and generosity of heirloom vegetables, giving gardeners an exceptional crop of large, flavoursome cabbages.

Benefits and uses

Quintal d'Alsace cabbage stands out as the essential choice for anyone who loves winter vegetables and traditional preserves. Its primary calling is home-made sauerkraut, thanks to its exceptionally firm heads and crisp texture, which stands up perfectly to fermentation.

This variety is perfectly suited to family gardens seeking winter self-sufficiency, to raised beds optimised for intensive production, and to market gardeners specialising in storage vegetables. Its remarkable hardiness makes it accessible to beginner gardeners while meeting the standards of experienced growers.

The large flat heads it produces can reach impressive sizes, guaranteeing a generous yield from a small area. This exceptional productivity makes it a strategic choice for maximising autumn harvests and stretching your stores into the first hard frosts.

Technical features and varietal innovation

The genetics of Quintal d'Alsace rest on a rigorous selection favouring climatic hardiness and resistance to fungal diseases. This old variety has naturally adapted to the weather swings of a continental climate, taking temperature shifts and autumn damp remarkably well.

Vilmorin seeds come from a certified production process, guaranteeing an optimal germination rate within 5 days of sowing in temperate conditions. Varietal purity ensures perfectly uniform plants, avoiding unwanted variations in earliness or shape.

The flat, dense structure of the heads comes from a specific cell architecture, giving excellent keeping quality in store and a natural resistance to thermal shock. This shape also makes slicing easier for cooking and improves the yield when processing into sauerkraut.

Sowing and crop management

Sowing is best done from March to mid-June, in a seedbed or directly in place depending on your regional climate. For a seedbed, set the seeds 1 cm deep in a light, well-drained compost, holding a steady temperature of 15 to 18°C.

Transplanting takes place once the plants have 4 to 5 true leaves, usually 6 weeks after sowing. Allow 60 cm between plants to let the bulky heads develop fully. A deep, cool soil rich in organic matter is the foundation of a successful crop.

Regular but moderate watering avoids water stress while preventing fungal disease. An organic mulch keeps the soil cool and limits weed competition. Harvest runs from August to December, depending on sowing date and on how much you need.

Expert tips and companion planting

Pairing with aromatic herbs is a remarkably effective, chemical-free strategy against the pests specific to cabbage. Plant thyme, rosemary, sage or dill along the edge of the bed to create a scent barrier that deters cabbage white butterflies and mealy cabbage aphids.

To get the best winter storage, harvest the heads after the first light frosts, which naturally improve both firmness and flavour. Store them in a cool, airy cellar, hung roots upwards, to keep them right through to February.

A crop rotation of at least 3 years prevents soil exhaustion and limits disease pressure. Alternate with legumes, which enrich the soil in nitrogen, then with less demanding crops. This practice guarantees consistent yields and the best plant health.

For home-made sauerkraut, pick the heads good and firm and use them within 48 hours of cutting. Slicing them thinly and evenly, combined with the right amount of salt, triggers an authentic, flavoursome lactic fermentation.
