You can extract lavender oil by steam distillation.
This process uses steam to pull the essential oil out of the lavender flowers.
It’s one of the oldest and most trusted ways to get pure lavender essential oil.
If you’ve ever wondered how to extract lavender oil by steam distillation, the good news is that it’s very doable at home with the right setup.
In this post, we’ll walk through how to extract lavender oil by steam distillation step by step and share tips for getting the best results.
Let’s get started.
How to Extract Lavender Oil by Steam Distillation
To extract lavender oil by steam distillation, you need three basic things: lavender, water, and a still.
Here’s how the process works from start to finish.
1. Harvest and Prepare Your Lavender
The first step in extracting lavender oil by steam distillation is harvesting at the right time.
Pick lavender flowers in the morning after the dew has dried but before the sun gets too hot.
This is when the oil content is at its highest.
Cut the stems just above the woody part of the plant.
You can use fresh or dried lavender to extract lavender oil by steam distillation.
If you use dried lavender, make sure it’s fully dry to avoid mold in the still.
For fresh lavender, remove the flowers from the stems before you load them into the still.
2. Set Up Your Steam Distillation Equipment
To extract lavender oil by steam distillation, you need a setup that lets steam pass through the plant material.
A copper or stainless steel still works best.
You’ll also need a heat source, a condenser, and a collection vessel.
Fill the bottom of the still with water, leaving enough room for steam to build.
Place the lavender flowers in the steam basket above the water.
Make sure the flowers are loosely packed so steam can move through them evenly.
If you pack them too tight, the steam won’t carry the oil out properly.
3. Heat the Still and Let the Steam Work
Turn on your heat source and bring the water to a gentle boil.
As steam rises, it passes through the lavender flowers.
The heat opens the oil glands in the plant and the steam picks up the lavender oil.
This is the heart of how to extract lavender oil by steam distillation.
Keep the heat steady but not too high.
A rolling boil is fine, but a violent boil can scorch the plant material and ruin the scent.
The steam and oil vapor travel together into the condenser.
4. Condense the Vapor Back into Liquid
The condenser cools the steam and oil vapor back into liquid form.
Cold water runs through the condenser jacket to speed up this process.
The liquid that drips out is a mix of water and lavender oil, called hydrosol or floral water.
You’ll collect this liquid in a separate container.
When you extract lavender oil by steam distillation, the oil floats on top of the water because oil and water don’t mix.
This makes it easier to separate them later.
5. Separate the Oil from the Water
Once the distillation is done, let the collected liquid sit for a while.
The lavender oil will rise to the top and the hydrosol will stay below.
Use a separating funnel or a pipette to carefully pull off the oil layer.
If you extract lavender oil by steam distillation on a small scale, you might only get a few drops.
That’s normal because lavender flowers don’t contain a huge amount of oil.
Store your oil in a dark glass bottle away from heat and light.
The hydrosol can also be saved and used as a natural toner or linen spray.
Tips for Better Results When You Extract Lavender Oil by Steam Distillation
Getting a good yield when you extract lavender oil by steam distillation takes a little practice.
Here are some tips to help you along the way.
1. Use the Right Lavender Variety
Lavandula angustifolia, also called true lavender, gives the best oil for home distillation.
It has a sweet, floral scent and a high oil content compared to other types.
Lavandin has more oil but the scent is more camphor-like and less desirable.
2. Don’t Overfill the Still
Leave plenty of space for steam to circulate around the flowers.
If the still is too full, the steam can’t reach all the plant material and you’ll leave oil behind.
A good rule is to fill the steam basket no more than two-thirds full.
3. Keep the Heat Consistent
A steady, moderate heat works best when you extract lavender oil by steam distillation.
Too much heat can burn the flowers and give the oil a smoky or bitter smell.
Too little heat and the steam won’t be strong enough to carry the oil out.
4. Distill in Small Batches
Small batches are easier to manage and give better quality oil.
You don’t need a huge amount of lavender to extract lavender oil by steam distillation.
A few cups of fresh flowers can yield a small bottle of oil.
So, How Do You Extract Lavender Oil by Steam Distillation?
You extract lavender oil by steam distillation by passing steam through lavender flowers and then condensing the vapor back into liquid.
From there, you separate the oil from the hydrosol and store it properly.
It takes patience and the right equipment, but the result is pure, fragrant lavender oil you made yourself.
Whether you grow your own lavender or buy it fresh, learning how to extract lavender oil by steam distillation is a rewarding skill.
Once you try it, you’ll never look at a bottle of lavender oil the same way again.
