Rose producers have trusted this metal for generations. A copper still spreads heat evenly, so the petals never scorch and the oil keeps its fine, rounded scent. The plant in this photo shows large stills working side by side with modern stainless steel condensers.
What you see in the photo
On the left and in the centre stand two big stills on blue steel frames. In front of them, tall stainless steel columns lead the vapour to the condensers. Then the cooled liquid flows into the conical Florentine separators at floor level. Also, insulated pipes overhead carry steam and cooling water to every still.
Why a copper still for rose?
- Even heat: copper moves heat fast, so there are no hot spots on the wall.
- Clean aroma: many distillers find that the metal gives a smoother, rounder rose oil.
- Tradition: rose oil and rose water have come from such stills for centuries.

Copper still and stainless steel together
We build the still body in copper, while the condenser, separator and pipework use AISI 304 or 316 stainless steel. As a result, you get the classic quality where the flowers touch the metal, and easy cleaning everywhere else.
For example, the plant above combines several stills with a cohobation unit, so it also recovers the oil that stays in the rose water.
How a copper still works
- First, the operator fills the still with fresh petals and water.
- Then steam or direct heat brings the water to the boil.
- Next, the vapour rises and carries the oil to the condenser.
- Finally, rose oil and rose water separate in the Florentine flask.
In short, a copper still gives you traditional quality with modern control. See our models on the essential oil distillation units page.
FAQ
Does it need extra care? Yes, a little. Regular cleaning keeps the inner surface bright and the oil clean.
Can I use a copper still for lavender? Yes. However, most lavender producers choose stainless steel, because the metal matters most for rose.
