Your First Run With a New Copper Still: A Step-by-Step Cleaning, Seasoning, and Water-Test Checklist

A new copper still arrives bright and full of promise, but it isn't ready for real work yet. Between the shop floor and your workspace it can pick up dust, flux residue, fingerprints, and oils from handling. Your first run isn't really about output. It's a calibration experiment: you learn how your copper, your heat, and your cooling water behave before anything that matters goes in the pot.

This page is laid out the way the rest of The Distillers List is: as lists you can scan, check off, and come back to. Start with the cleaning checklist, then use the still lists further down to compare sizes, budgets, heat sources, and uses.

One line before we start: owning a still is legal in the US, but distilling alcohol requires federal (TTB) permits. Follow all federal, state, and local law. Everything below uses only water and vinegar.

Checklist 1: Unbox and Inspect

1. Lay out every part. Pot, cap, column or thumper if you have one, worm, and connectors. Check them against your order.
2. Look inside each piece with a flashlight. You're checking for loose debris, packing material, or anything rattling around in the tubing.
3. Check the joints and seams. Note any spots that look dull or uneven so you can watch them closely during the water test.
4. Dry-fit the connections. Put the still together without heat or water so you know how everything lines up before it gets hot.

Checklist 2: The Wash

Copper doesn't need anything harsh. Gentle cleaning protects the surface you're about to put to work.

1. Rinse every part with warm water. Flush the worm and any tubing until the water runs clear.
2. Wash with a mild dish soap and a soft cloth or sponge. Skip steel wool, scouring pads, and bleach. They scratch or react with copper.
3. Rinse thoroughly. Soap left in the still will show up later. Rinse until there are no suds, then rinse once more.
4. Brighten the outside if you want to. A paste of vinegar or lemon juice with a little salt lifts tarnish. Rinse it off fully afterward.
5. Let everything air-dry before you reassemble.

Checklist 3: The Seasoning (Vinegar) Run

This is where the alchemy starts. A vinegar run sends hot, slightly acidic vapor along the same path your future runs will take. It cleans the inside surfaces you can't reach with a cloth. Many hobbyists call it "seasoning" the still.

1. Fill the pot partway with a mix of white vinegar and clean water. Many people use roughly half and half. Don't fill to the brim. Leave headroom for boiling.
2. Assemble the still and connect your cooling water to the worm or condenser before you turn on the heat.
3. Heat slowly. Low and steady lets you watch how fast the pot comes up to temperature on your heat source. Write it down. It's your first real data point.
4. Run it until a steady stream comes out of the worm, then keep it going for a while to flush the full vapor path.
5. Throw out everything that comes out. It's cleaning liquid, not product. Don't drink it and don't save it.
6. Cool down, drain, and rinse the pot and every part with clean water.

Checklist 4: The Water Test

Now run the experiment again with nothing but clean water. This is your control. It tells you whether the still is tight and your cooling keeps up.

1. Fill the pot partway with clean water only.
2. Heat gradually and watch every joint. Look for drips, hissing, or wisps of vapor at the cap, thumper connections, and the worm.
3. Mark any leak while the still is cool. Never touch hot copper or tighten fittings under heat. Many old-timers seal small gaps with a paste of rye flour and water, applied with the still cool.
4. Check your cooling. What comes out of the worm should be cool to the touch. If it's warm, you need more cooling-water flow or a lower heat setting.
5. Note your settings. Burner setting or controller setting, time to first drip, and how steady the flow is. This becomes your baseline.
6. Drain, rinse, and dry fully before storing the still.

Checklist 5: Safety Basics for Every Run

• Run propane burners outdoors or in a well-ventilated space, never in a closed room.
• Never leave a running still unattended.
• Keep a fire extinguisher within reach.
• Keep children and pets away from hot copper.
• Always start your cooling water before you apply heat.
