To maximize the surface area exposed to the steam and help release the essential oil, lightly crush or bruise the leaves. Ensure all equipment is clean and, if possible, made of glass or stainless steel to avoid contaminating the delicate oil.
Ensuring Your Peppermint Oil Stays Potent and Pure Over Time
As the water heats, it transforms into steam, which travels upward into the basket. This includes a boiling chamber for the water, a distillation basket to hold the botanicals, a condenser coil to cool the vapor, and a receiving flask to collect the final product.
The plant should be at its peak potency, which is typically just before it flowers. The condenser, usually a coiled tube surrounded by cool water, rapidly cools the vapor back into a liquid.
