When it comes to choosing the best gauge of copper for a moonshine still, there are a few factors to consider. The gauge of copper refers to its thickness, with lower gauge numbers indicating a thicker copper sheet. In the case of moonshine stills, the most commonly used gauges are 20 oz./22-gauge, 32 oz./18-gauge, and 48 oz./16-gauge.
The 20 oz./22-gauge copper is the standard choice for hobby stills, and for good reason. This gauge strikes a balance between durability and cost-effectiveness. The thickness of 20 oz./22-gauge copper provides sufficient strength and structural integrity for a hobby still, ensuring that it can withstand the heat and pressure generated during the distillation process. Additionally, this gauge is easier to work with and shape, making it an ideal choice for DIY moonshiners.
However, if you are looking for a more heavy-duty and professional-grade moonshine still, you might consider opting for thicker gauges such as 32 oz./18-gauge or 48 oz./16-gauge. These gauges offer even greater durability and longevity, making them suitable for commercial or high-volume distillation operations. The thicker copper sheet provides enhanced heat conductivity and better heat retention, which can contribute to more efficient and consistent distillation.
That being said, it's important to note that the choice of gauge also depends on the specific design and construction of the moonshine still. A well-designed still with reinforced joints and proper insulation can compensate for a slightly thinner gauge of copper. On the other hand, a poorly constructed still with weak joints may require a thicker gauge to prevent leaks and ensure safety.
In my personal experience as a brewer and distiller, I have found that a 20 oz./22-gauge copper still is more than sufficient for most hobbyist needs. I have successfully used this gauge for small-scale distillation of spirits such as whiskey and brandy, achieving excellent results in terms of flavor and quality. The key is to invest time and effort into building a well-crafted still with attention to detail and proper craftsmanship.
To summarize, the best gauge of copper for a moonshine still depends on your specific requirements and budget. For most hobbyists, a 20 oz./22-gauge copper still is a reliable and cost-effective choice. However, if you are operating a larger-scale or commercial distillation setup, thicker gauges like 32 oz./18-gauge or 48 oz./16-gauge may be more suitable. Ultimately, the quality of the still's construction and design is just as important as the gauge of copper used.
