There are many products on the market, known as flower or floral water, hydrolats and hydrosols. Various definitions exist. We call ours Hydrolats and can assure you that all Bay House labelled Hydrolats are the genuine byproduct of the essential oil distillation process. During this process the essential oil is created by plant material coming into contact with steam or water, and as the steam condenses it separates into essential oil and a water that contains minute amounts of essential oil. Some Distillers use this same water again and again in the distillation phase (Cohobation) to maximise the extraction of the essential oil. No preservatives or alcohol have been added to the final product.
