Liatris

In the fields of the North American prairie, harvesters collect mature Liatris stalks in late summer when the roots store peak aromatic compounds. The roots are washed, sliced, and placed into a stainless steel extractor. Solvent extraction draws out the fragrant oils, producing a thick, amber-colored absolute. After maceration, the solvent evaporates under reduced pressure, leaving a resinous concentrate rich in lactones and sesquiterpenes. Some houses employ supercritical CO2 to preserve delicate green notes while reducing solvent residues. The final product is filtered, tested for purity, and sealed in amber glass to protect it from light and oxidation. Throughout the process, temperature never exceeds 45 °C, preserving the fresh, grassy character that defines Liatris.
