100Lt 4 inch Vodka Gin Alcohol Copper Reflux Still / Flute Column Still

100L 4-Inch Copper Reflux Still / Flute Column Still for Vodka & Gin Distillation

1. Overview

A 100L 4-inch copper reflux still (also called a flute column still) is a professional-grade distillation system designed for producing high-purity spirits like vodka, gin, and neutral alcohol. Its reflux design allows for multiple distillations in a single run, achieving alcohol concentrations up to 95% ABV while maintaining precise flavor control.

2. Key Features & Specifications

• Capacity: 100 liters (ideal for small to medium-scale distilling).

• Material: Pure copper – Removes sulfur compounds, enhances smoothness, and improves flavor.

• Column Diameter: 4 inches (~10 cm) – Balances distillation speed and purity.

• Type:

  • Reflux Still: Maximizes alcohol purity (best for vodka & neutral spirits).

  • Flute Column Still: Modular plates for customizable reflux control (better for gin & flavored spirits).

• Heating Options:

  • Electric heating elements (SCR-controlled for precision).

  • Gas/propane fire (traditional method).

  • Steam jacket (for commercial setups).

• Condenser:

  • Shell & Tube or Liebig Condenser – Efficient vapor cooling.

  • Optional dephlegmator (reflux condenser) for enhanced purity.

• Additional Features:

  • Temperature & pressure ports.

  • Adjustable reflux ratio (for flavor customization).

  • Tri-clamp fittings (sanitary, easy disassembly).

3. How It Works

• Boiler: The wash is heated, producing alcohol vapor.

• Reflux Column: Vapor rises, condenses, and re-evaporates multiple times (increasing ABV).

• Plates/Obstructions:

  • Perforated plates (in flute columns) – Allow controlled reflux.

  • Packing material (copper mesh, ceramic raschig rings) – Increases surface area for better purification.

• Condenser: Converts vapor back into liquid, collected as high-proof distillate.

4. Best Uses

✔ Vodka – Achieves neutral, ultra-pure alcohol (95% ABV+).
✔ Gin – Add a botanical basket for vapor infusion.
✔ Neutral Spirits – For liqueurs, bitters, or dilution.
✔ Whiskey (Light) – Can be used with reduced reflux for more flavor retention.

6. Buying Considerations

• Copper Thickness (1.5mm+ for durability).

• Modularity (Can you add/remove plates?).

• Heating Method (Electric vs. gas vs. steam).

• Safety Features (Pressure release valve, thermometer).

• Brand Reputation (Avoid cheap, thin-walled stills).
