Distillation is the process of separating alcohol from water and other components through controlled heating and cooling. This ancient technique, refined over centuries, is what transforms fermented liquids into the clear, potent spirits we know today.
Modern distillation often requires precise measurements and conversions. Professional distillers frequently use tools like an mg to ml converter when working with flavor compounds and additives to ensure accuracy in their formulations.
The Science of Distillation
The process begins with a fermented liquid called a "wash" or "mash." When heated, alcohol evaporates at a lower temperature than water (78.4°C vs 100°C), allowing for separation. The alcohol vapor is then cooled and condensed back into liquid form.
This temperature difference is crucial to the distillation process. However, it's not just about alcohol and water - hundreds of other compounds with different boiling points are also present, creating the complex flavor profiles we associate with different spirits.
Types of Distillation
There are two main types of distillation used in spirit production:
Pot Distillation
Uses traditional copper pot stills, producing spirits with more character and flavor compounds. This method is batch-based, meaning each distillation run is separate and distinct. Pot distillation is favored for whisky, cognac, and other spirits where character and complexity are prized.
Column Distillation
Uses tall columns for continuous distillation, creating cleaner, more neutral spirits. This method allows for continuous operation and greater efficiency, making it ideal for producing vodka, gin, and other spirits where purity is the goal.
The SACHI Distillation Process
For SACHI, we employ a carefully designed distillation process that preserves the unique characteristics of our soy-based wash while achieving the purity and smoothness expected from a premium spirit. Multiple distillation runs allow us to separate and concentrate the most desirable flavor compounds.
The protein-rich nature of soybeans creates unique challenges and opportunities during distillation. We've developed specialized techniques to handle the amino acids and other compounds that give SACHI its distinctive character.
The Art of Making Cuts
The "cuts" made during distillation - separating the heads, hearts, and tails - are crucial for quality. This is where science meets artistry:
- Heads: The first vapors to come off the still, containing volatile compounds that can be harsh or unpleasant
- Hearts: The middle portion containing the purest alcohol and best flavors - this becomes the final product
- Tails: The final vapors, containing heavier compounds that can add unwanted flavors
Only the "hearts" containing the purest alcohol and best flavors make it into the final product. The skill lies in knowing exactly when to make these cuts, which varies based on the raw materials, fermentation conditions, and desired flavor profile.
The Role of Copper
Copper plays a vital role in distillation, acting as a catalyst that removes sulfur compounds and other undesirable elements. The interaction between alcohol vapors and copper surfaces helps create smoother, cleaner spirits.
Many distilleries use copper pot stills or copper elements in column stills specifically for this purifying effect. The amount of copper contact can be adjusted to influence the final spirit's character.
Master Distillers: Artists and Scientists
Master distillers spend years perfecting their craft, learning to identify the precise moments when to make cuts to achieve the desired flavor profile. They must understand not just the technical aspects of distillation, but also how different variables affect the final product.
Each distillation run is unique, influenced by factors like ambient temperature, humidity, barometric pressure, and the specific characteristics of that batch's fermentation. The master distiller's expertise lies in adapting to these variables while maintaining consistency.
Innovation in Modern Distillation
Modern distillation combines traditional techniques with advanced technology. Computer-controlled systems can monitor temperatures and flow rates with incredible precision, while still allowing for the human judgment that defines great spirits.
For innovative products like SACHI, this combination of tradition and technology is essential. We honor the ancient art of distillation while pushing the boundaries of what's possible with new ingredients and techniques.
