Winter-harvested vegetables are known for their richness in free amino acids (for long spring onion, 547 mg / 100g, high concentration of alanine, glutamate, asparagine, serine, glutamine...) and their sweet taste. Winter-harvested long green onions are called "Yuki-shita negi", which means "Japanese leek under the snow".
