Hydrodistillation is a traditional approach where plant material is immersed in water and heated. The vapor, containing essential oil, is condensed to separate oil from water (hydrolate). While it preserves certain plant aromas better, it’s considered less efficient than steam distillation. Choice depends on factors like plant type and desired oil properties.

Steam distillation involves passing steam through aromatic plants, carrying volatile compounds that condense into water (hydrolate) and oil. This efficient method preserves oil and hydrolate quality without causing thermal degradation. This is how we distil our rockrose
