Copper vs. Stainless Steel Distillation Equipment: Which is Better for Essential Oils?

The essential oil industry has seen significant growth in recent years. With the increasing demand for pure and high-quality oils, the choice of distillation equipment has become more crucial than ever. Two metals, in particular, dominate the market: copper and stainless steel. But which one stands out when it comes to producing the best essential oils? Before delving into the details, if you’re eager to explore some top-notch distillation equipment, do visit the Copper pro site.

Historical Perspective: The Age-old Use of Copper

Copper distillation isn’t new. This metal has been in use for distillation purposes since ancient times. Distillers from various epochs valued copper for its unique properties, especially its high thermal conductivity. This ensures even heat distribution, a crucial factor in the distillation of not just essential oils but spirits as well.

The Modern Marvel: Stainless Steel’s Entry

With the onset of modern manufacturing techniques in the 20th century, stainless steel became a go-to material for various industrial applications, including distillation. Its durability, resistance to corrosion, and sleek appearance made it an instant favorite among many producers.

Comparative Analysis: Copper vs. Stainless Steel

1. Heat Conductivity:

  • Copper: Boasts a high thermal conductivity, ensuring that the heat spreads evenly across the distillation pot. This uniform heat is essential for producing consistent batches of essential oils.
  • Stainless Steel: While it conducts heat, it’s not as efficient as copper. There might be certain hotspots that could affect the distillation process.

2. Durability & Maintenance:

  • Copper: Requires regular maintenance to prevent corrosion. However, with proper care, copper distillation units can last for generations.
  • Stainless Steel: Highly durable and relatively low maintenance. It’s resistant to rust and can withstand the test of time with minimal care.

3. Reactivity & Sulphur Removal:

  • Copper: Interacts with sulphur compounds, a beneficial trait as it removes unwanted sulphur-based compounds during distillation. This is especially vital in spirit distillation.
  • Stainless Steel: Doesn’t offer the same reactivity. If the raw material has high sulphur content, it might not be the best choice.

4. Aesthetics & Tradition:

  • Copper: Carries a certain old-world charm. Many traditionalists prefer copper not just for its functional benefits but also for its aesthetic appeal.
  • Stainless Steel: Offers a modern, industrial look. It’s preferred by those looking for a sleek and contemporary appearance.

5. Cost Implication:

  • Copper: Tends to be pricier due to its unique benefits and aesthetic appeal.
  • Stainless Steel: More cost-effective initially, but one needs to consider the long-term benefits of copper, especially in terms of product quality.

Which is Better for Essential Oils?

The answer isn’t straightforward. Both metals have their pros and cons. If you’re looking for high thermal conductivity, reactivity, and traditional aesthetics, copper is your best bet. However, if durability, low maintenance, and cost-effectiveness are your top priorities, stainless steel is worth considering.

However, one must not forget the role of craftsmanship. A well-crafted copper distillation unit from a reputed manufacturer can significantly outperform a sub-par stainless steel unit and vice versa. It’s essential to consider the overall quality of the equipment, not just the material.


While both copper and stainless steel have their place in the distillation world, your choice will boil down to your specific needs, budget, and preferences. Always prioritize quality and craftsmanship over mere material choice. And if you’re in the market for top-tier distillation equipment, don’t forget to visit the Copper Pro site.
