What Your Still
Is Made Of
Most competitors don't publish this level of detail. We do — because transparency is part of what separates a premium handcrafted still from a mass-produced one.
1.1mm Hand-Hammered Solid Copper
Every CopperHolic still is formed from solid copper sheet at 1.1mm thickness — significantly heavier and more durable than the 0.6–0.8mm copper used by most competitors at similar or lower price points.
Thicker copper matters for two reasons. First, it holds up better over years of repeated heating, cooling, and cleaning. Second, it distributes heat more evenly during distillation, leading to better results whether you're producing essential oils, hydrosols, or distilled water.
The hand-hammered finish isn't just decorative — it's part of the traditional alembic craftsmanship process and contributes to the structural integrity of each piece.
Lead-Free Silver Solder on Every Joint
All soldered joints on CopperHolic stills use lead-free silver solder. This is a critical safety detail that many buyers overlook when comparing brands.
Lead-free solder means no lead comes into contact with any surface that touches vapor, condensate, or liquid during distillation. This matters for any application — whether you're making hydrosols for skincare, essential oils, distilled water, or anything else used on or near the body.
If a seller doesn't clearly state that their solder is lead-free, ask before you buy. This is one of the most important material decisions in any copper still.
Traditional Flour Paste Seal
The connections between the pot, onion head, swan neck, and condenser seal using the traditional alembic method — a simple flour-and-water paste applied at the joint between the pot and dome.
This paste is food-safe, easy to make at home, and has been used in alembic distillation for centuries. It hardens during heating to create a vapor-tight seal, then is cleaned off and reapplied before each use.
No synthetic adhesives, silicone, or rubber gaskets touch the vapor path in a CopperHolic still.
Quick Clean Routine
- Rinse all components with warm water while still slightly warm
- Remove and discard the flour paste seal
- Allow all parts to air dry completely before storing
- Do not use abrasive scrubbers or harsh chemical cleaners
Deep Clean Cycle
- Run a vinegar-water cleaning cycle whenever you notice residue
- For exterior tarnish, use a paste of lemon juice and salt
- Never use commercial copper polish on interior surfaces
- For detailed guidance, see the Still Manual

If they can't answer clearly, that tells you something.
Yes. All CopperHolic stills are assembled with lead-free silver solder. No lead touches any surface in the vapor or liquid path.
All CopperHolic stills use 1.1mm hand-hammered copper — significantly thicker and more durable than the 0.6–0.8mm copper used by most competitors.
Yes. Lead-free silver solder, solid copper construction, and traditional flour-paste sealing mean no harmful materials contact your output during distillation. Essential oil and hydrosol production doesn't require permits in the US.
Yes. Run one cleaning cycle with vinegar water before your first real batch. This removes manufacturing residue and prepares the copper — takes about an hour.
Rinse all components with warm water, remove the flour paste seal, and let everything air dry. Run a vinegar cleaning cycle every 5–10 uses for deeper maintenance.
Distilling alcohol in the US requires a federal fuel alcohol permit and may require state permits. CopperHolic stills are marketed for botanical and educational use. See our guide to still ownership laws.
With proper care and cleaning, a well-maintained copper alembic still can last a lifetime. The 1.1mm copper thickness and lead-free silver solder joints are built for long-term durability.
