The choice between varieties of flax—specifically, fiber flax grown for textiles versus oil flax cultivated for seed—dictates the agricultural approach. Cold pressing is a specific variation of this method, conducted at lower temperatures to preserve the oil's natural chemical integrity, resulting in a product prized for its purity and authentic properties.
