Proud market leader in Spinach

The rising consumer demand for fresh spinach is undeniable. And we get why. Spinach is a nutrient-packed superfood, supporting multiple health benefits and is perfect for multiple culinary moments—from fresh salads to cooked meals and stir-fries. Plus, spinach’s ability to be grown organically and sustainably makes it a favorite among health-conscious consumers. But when realizing that developing a new spinach variety takes about five years, we always need to think far ahead as a breeding company. So, that’s exactly what we do.

Spinach specialists for maximum resistance

If you know about spinach, you know about downy mildew. Since the start of our spinach breeding program, 35 years ago, we successfully started breeding for resistance against this disease. Today, we’re proud market leader in both baby spinach and bunching varieties. We make sure to stay ahead of the latest types and isolates of downy mildew and white rust. And because our varieties are resilient to local physios, they’re perfect for organic cultivation. This allows us to offer growers a wide range of varieties that have the maximum resistance available in the market today.

Scientific innovation and an in-depth trial strategy

At KWS, we believe in the power of seeing results firsthand. That’s why we conduct intensive trials under different conditions and regularly visit our customers to understand their needs. This hands-on approach, combined with cutting-edge science and in-depth know-how has solidified our leadership in fresh spinach. With access to advanced technologies and extensive know-how, we continuously push the boundaries of what’s possible in spinach resistance. In addition, our extensive trial program teaches us how we can optimally slot our varieties into production schedules, ensuring maximum yields while keeping the cost per pound low.

“The genetics of KWS are tremendous. Organic farmers face constant challenges with mildew, but KWS always proves to stay on top of it. With new genetics every season, KWS allows growers to always produce a healthy, robust crop.”

Consistency in volume and quality

Consumers and the supply chain demand consistency in volume and quality, 365 days a year. We have developed the Spinach 365 program to respond to this need. Spinach 365 helps give consumers access to uniform, high-quality, fork-sized spinach that has a good crunch – all year round, and in the right volumes. This way, we encourage consumers to make repeat purchases in supermarkets. As the varieties of Spinach 365 slot together perfectly, they ensure delivery can be guaranteed. In addition, the uniform leaves and petioles make for easier processing and packing, saving you money on packers.

“We always make sure our spinach varieties don’t just excel in resistances, but have the best phenotypes, too. That means our varieties have high uniformity and have thick, round, and dark green leaves with a good crunch and long shelf life.”
