The Science of the Still: Types and Materials Used in Spirits Distillation
When we raise a glass to savor a fine spirit, we often overlook the silent hero in the background: the still. Stills, the alchemical vessels of distillation, play a pivotal role in the transformation of raw ingredients into the rich, complex flavors we love.
In this post, we explore the world of stills, discussing the different types that shape spirits—pot stills, column stills, and hybrid stills. We’ll also delve into the impact of materials like copper and stainless steel on the character of the final spirit.
Types of Stills
Each type of still has a distinct personality and purpose in the world of distillation. The historical context of these still designs reveals the evolution of distillation techniques and their role in crafting today’s spirits.
-
Pot stills, with their traditional design and direct-fired approach, offer an authentic glimpse into the heart of distillation. These stills leave an indelible mark on the character of a spirit, enhancing its depth, richness, and aroma.
-
Column stills, with their towering structure and continuous operation, are masters of purity, yielding clean, pristine spirits that shine with clarity.
-
Hybrid stills are where innovation meets tradition. These stills combine the best of both pot and column designs. The versatility of hybrid stills allows distillers to craft spirits with a spectrum of flavor profiles, offering the best of both worlds.
What are Distillation Stills Made of?
Copper and stainless steel are two common materials used in still construction, each imparting distinct characteristics to the spirits they produce.
Copper, with its historic significance in distillation, plays a pivotal role in shaping the flavor and aroma of spirits. When copper comes into contact with the vapor during distillation, it interacts with sulfur compounds, helping to eliminate unwanted impurities.
This reactivity with sulfur compounds results in a smoother and cleaner spirit. Copper is also known for its heat conductivity, ensuring even heat distribution during distillation, which can lead to a well-balanced and refined final product. Distilleries often turn to copper stills when aiming to create spirits with a more complex, nuanced character.
On the other hand, stainless steel, with its modern and durable attributes, maintains a high level of purity throughout the distillation process. It doesn’t react with the vapor in the same way as copper, making it ideal for producing spirits that reflect the true essence of the raw ingredients. Stainless steel stills provide a level of precision and clarity in distillation, resulting in spirits that are often pristine and unadulterated by the material. Distillers seeking to highlight the natural flavors and characteristics of their ingredients often opt for stainless steel stills in their production process.
The choice between copper and stainless steel ultimately depends on the desired flavor profile and character of the spirit a distillery aims to create. Both materials have their advantages and can significantly influence the end product, making them crucial considerations in the art of spirit production.
As we conclude our journey, let’s raise our glasses to the stills that silently shape our spirits. Their role is as vital as it is understated. With a newfound appreciation for the significance of still types and materials in spirits distillation, we encourage you to explore the world of spirits with a discerning palate, savoring each drop as a testament to the craftsmanship of still and distiller.
Cheers!
