Highlander Series 20 Gallon Copper and Stainless Steel Pot Still with Thumper

The Highlander Series 20 Gallon Copper and Stainless Steel Pot Still with Thumper is a traditionally inspired, high-capacity distillation system engineered for distillers who demand uncompromising quality, durability, and authentic spirit character. Designed using proven pot still and thumper principles, this system delivers smooth vapor flow, enhanced proof potential, and consistent results across large production runs.

Built from 16 and 18 gauge copper and reinforced with stainless steel components, this still offers exceptional structural strength and thermal stability. Unlike mass-produced systems that rely on soft soldered seams, the Highlander Series is constructed using TIG brazing for all joints, producing cleaner, stronger, and more heat-resistant connections. Every component - from the oversized boiler to the properly matched thumper and efficient coil condenser, is purpose-built to perform reliably while honoring traditional distillation methods.

Why TIG Brazing And Heavy-Gauge Copper Matter

TIG brazing creates joints that are significantly stronger and cleaner than soldered seams, offering superior resistance to heat cycling, leaks, and structural fatigue. Combined with 16 and 18 gauge copper, this construction ensures stable heat transfer, consistent vapor behavior, and long-term reliability. This is professional-grade fabrication built for serious distillation.

What The Thumper Does

The included 8 gallon thumper acts as a secondary distillation chamber positioned between the boiler and condenser. As vapor passes through the liquid inside the thumper, it undergoes an additional distillation step during the same run.

Benefits include:

• Higher proof output without stripping flavor

• Richer, fuller spirit character

• Ability to charge with low wines, mash, or botanicals

• Improved consistency and smoother cuts

The thumper is properly sized to balance vapor flow from the 20 gallon boiler for optimal performance.
