A Boka reflux still, also known as a Bokakob still, is a type of distillation apparatus that is widely used by hobbyists and enthusiasts to produce high-quality spirits and liquors. It was originally designed by a man named Alex Bokakob in 2001 and has undergone several modifications and improvements since then.
The Boka reflux still consists of two main components: a stove-top boiler and a reflux column. The boiler is used to heat a mixture of water and fermented liquid, such as a mash or wash, which contains the desired alcohol to be distilled. The heat from the stove vaporizes the alcohol, which then rises up into the reflux column.
The reflux column is the heart of the Boka still. It is a tall, vertical tube that is packed with a material called reflux packing. The purpose of the packing is to create a large surface area for the vapor to come into contact with, promoting condensation and reflux. The design of the packing allows for the separation of impurities and unwanted compounds from the alcohol vapor, resulting in a cleaner and purer distillate.
At the top of the reflux column, there is a condenser, which is responsible for cooling the vapor and turning it back into a liquid. The condenser typically consists of a coiled tube or a series of plates that are cooled by either water or air. As the vapor flows through the condenser, it loses heat and condenses into liquid form, known as the distillate.
One of the unique features of the Boka reflux still is its dual slant-plate design. The slant-plates are positioned inside the reflux column at an angle, which helps to create a more efficient and effective separation of the vapor. The plates act as barriers, causing the vapor to condense and trickle down the column, while the lighter compounds continue to rise upwards. This process, known as reflux, allows for multiple distillations to occur within the column, resulting in a higher level of purity in the final product.
The Boka reflux still is favored by many distillers due to its simplicity, efficiency, and versatility. It can be easily constructed using readily available materials and can be scaled up or down depending on the desired batch size. Additionally, the still can be customized and modified to suit individual preferences and requirements.
Personal Experience:
I have had the opportunity to use a Boka reflux still in my own distilling experiments, and I must say, it has been quite a remarkable experience. The design of the still allows for a great deal of control over the distillation process, resulting in a high-quality and flavorful spirit.
The use of the reflux column with its slant-plates provides excellent separation of impurities, resulting in a remarkably clean and pure distillate. I was amazed at how smooth and refined the final product turned out to be. The ability to customize the still to my liking, such as adding additional plates or modifying the reflux packing, allowed me to experiment and achieve the desired flavor profiles in my spirits.
The Boka reflux still is not only a reliable and efficient distillation apparatus but also a source of satisfaction and pride for those who enjoy the art of distilling. It offers a great opportunity for individuals to explore and refine their distilling skills, and the end result is a product that can rival commercial spirits.
The Boka reflux still is a versatile and effective distillation apparatus that allows hobbyists and enthusiasts to produce high-quality spirits and liquors. Its design, with a dual slant-plate reflux column, promotes efficient separation of impurities and provides control over the distillation process. Whether used for personal enjoyment or as a creative outlet, the Boka reflux still offers a rewarding experience for those passionate about the craft of distilling.
