aromatic hydrolates

The bottom one is the aromatic hydrolate, which has an aqueous part, a smaller part made up of aromatic molecules and another made up of non-aromatic components that are soluble in water. Then it has to be microfiltered and packaged to protect it from light and oxygen as it is so fragile that it quickly becomes contaminated with bacteria. For this reason, once opened, the hydrolates must be consumed within the following 6 months and kept at a constant temperature between 13 and 15 degrees.
