How much water I should pour into the distillation pot?
In order to answer this question, we have to know the approximate output of hydrolats and how many kilos of plants we can place in our column.
Output of hydrolats
The general rule for collecting hydrolats: “It is recommended to use approx. 0,5 kg of the raw material for obtaining1 L of hydrosol.” In case of using this proportion, you will get high-quality hydrolats with useful medical properties.
Column capacity
For example, we will distill rosemary by using 5 liter distillation kit. I’ve chosen this plant because of its weight. Most of the plants are lighter and take much more space of the column.
The 2-liter distillation column holds 0,5 kg of rosemary, which means we can receive 1 liter of hydrolats and 10-14 ml yield of essential oil.
In this case, during the distillation, we use 1 liter for collecting hydrolats and 1 liter for the steam evaporation (in fact, less than 1 liter but for safety, it’s better to pour more than less).
The 9-liter distillation column holds 2,25 kg of rosemary, as result, we can collect 4,5 liters of hydrolats and pour our pot with 6 liters of water.
Does it important the quality of water for making oil?
Distilled water is a type of purified water that has had both contaminants and minerals removed. Purified water has had chemicals and contaminants removed, but it may still contain minerals.
There is no reason to use “purified” or enriched water, because after the distillation you will lose all magnesium and calcium minerals.
