Product Overview
The Boben 500L & 300L Whisky Pot Still is a purpose-built double-distillation system designed solely for whisky production: a 500L Wash Still (for converting fermented grain/malt wash into low-wine) and a 300L Spirit Still (for refining that low-wine into the smooth, aromatic new-make spirit at the core of single malts, blended whiskies, and more).
Crafted with food-grade T2 copper (the gold standard for whisky distillation) and 304/316L stainless steel, this system delivers the classic copper-driven flavor profile-clean, fruity, and free of harsh sulfur notes-while ensuring scalability for small-batch or commercial distilleries.
Key Features (Whisky-Focused)
1. Whisky-Specific Double Distillation
500L Wash Still: Processes 500L of fermented malt/grain wash (barley, corn, rye) to produce low-wine (20–30% ABV)-the first step in concentrating sugars and flavors.
300L Spirit Still: Refines low-wine into new-make spirit (60–70% ABV) by precisely separating foreshots (harsh, unwanted alcohols), hearts (the smooth, flavorful core), and tails (rich, oily residues)-critical for whisky's distinct character.
2. Copper: The Whisky Maker's Secret
Sulfur Removal: Copper's catalytic reaction eliminates sulfur compounds (from grain fermentation) that would make whisky bitter or "metallic."
Flavor Enhancement: Copper encourages ester formation, adding fruity, floral notes (e.g., pear, vanilla) that define premium single malts.
Traditional Swan Neck: The iconic tapered copper neck (3.5° angle) controls vapor flow, preserving delicate grain/malt flavors.
3. Whisky-Optimized Design
Grain-Friendly Construction: Wide manways and smooth internal surfaces prevent grain mash clogs during distillation.
Controlled Heating: Electric heating bands (24–36kW for Wash Still; 18–24kW for Spirit Still) or steam coils deliver gradual, uniform heat-avoiding scorched grain flavors.
Reflux Control (Optional): Adjustable condenser valves let you fine-tune spirit strength and flavor (e.g., more reflux = lighter, smoother whisky; less = richer, maltier notes).
4. Durable & Compliant
304/316L Stainless Steel Base: Diamond-textured bodies resist corrosion from acidic grain wash, ensuring long-term use.
Food Safety Certified: Meets CE, UL, and FDA standards-safe for commercial whisky production worldwide.
