We use steam distilling to extract the essential oils from our plants. This process uses boiling water to produce steam, which is then directed though a container of lavender. As the steam passes through the plants, oil is released. The oil, in the form of a vapor, passes through a condenser. The condenser cools the vapors and returns the steam to a liquid form. Once cooled, the liquid drains into a separator and the oil settles on top of the water. The water is drained and the oil is bottled. The leftover water is called hydrosol. It has a more earthy smell with a slight lavender fragrance.
