The Digital Distiller: How Ambix Spirits Uses Arduino for Making Brandy

Introduction

Ambix Spirits, led by the innovative David Klein, exemplifies a pioneering approach in the world of distillation. They are a distillery making small batch, French-style brandy from over 200 varieties of cider apples grown on-site or locally sourced in Sonoma County, CA. Klein’s deep curiosity and passion for every facet of production are what drives his innovations and it’s surely behind his current and future success.

This case study explores how Klein's ingenious use of modern technology, especially Arduino microcontrollers, has revolutionized his brandy production processes, highlighting a blend of traditional craftsmanship and cutting-edge innovation.

Innovation in Pressing:

David Klein has harnessed the power of Arduino microcontrollers to transform the functionality of his Mori press, primarily used for pressing 30 tons of apples and 5 tons of Chardonnay grapes annually. The Mori press, originally equipped with a digital controller, now benefits from Klein’s modifications that enable precise pressure control. This fine-tuned control is critical for maximizing juice extraction efficiency and quality.

Arduino as a PLC:

By programming an Arduino to act as a programmable logic controller (PLC), Klein created a sophisticated system that gradually increases pressure, ensuring a more productive press. This system logs data on pressure and time, providing invaluable insights into the juice extraction process. With just $50 in hardware and a few hours of coding, Klein can now review detailed press logs, optimize pressing programs, and adjust settings to improve yield and quality.

Enhancing Equipment Functionality
Aging Cave with Automated Climate Control:

Klein's ingenuity extends beyond the pressing process. In his aging cave, an Arduino measures internal air conditions and communicates with a weather station to monitor external humidity and temperature. When conditions are optimal, the Arduino automatically ventilates the cave, ensuring the ideal aging environment for his spirits.

Fermentation Monitoring:

For the fermentation process, Klein employs an Arduino to monitor pressure and temperature, ensuring the integrity of the check valve. The system alerts him if the valve fails, allowing for immediate intervention. Additionally, data logs from the fermenter help Klein analyze yeast productivity and optimize fermentation phases, such as adjusting the chiller to save energy without compromising fermentation quality.

Future Developments
Distillation Process Automation:

Looking ahead, Klein plans to further automate his distillation process. By using an Arduino to monitor vapor temperatures, he aims to precisely control the 12-hour distillation process. This advancement will enable him to leave the still unattended while continuously recording data and receiving updates on the distillation stage.

Educational Resources:

For those curious about how to incorporate microcontrollers into their own harvest and production processes, Klein recommends learning electronics using resources such as Adafruit and Random Nerd Tutorials, which offer comprehensive guides for beginners. He also highlights Digi-Key for electronic supplies and suggests the ESP32 platform for Arduino projects.

Conclusion
Empowering Producers Who Have a Small Team (or no team at all):

Klein's approach demonstrates that with a modest investment in technology and some technical know-how, small-scale producers can significantly enhance their equipment's functionality. By integrating Arduino microcontrollers, Klein has achieved results comparable to higher-end, more expensive models, illustrating a path for others in the industry to follow.

For those looking to replicate such innovations, Klein emphasizes the importance of community support and resources. This is a great example of how TCW, for instance, is assisting in getting the word out for optimizing your investments, ensuring that even a $20,000 press can perform like a $50,000 model.

Through these inventive applications of technology, David Klein with Ambix Spirits continues to push the boundaries of what’s possible in wine and spirits, and sharing with all to encourage innovation in the industry.
