I have been doing some serious reading with a view to designing and constructing a 25l pot still and have come across the following in regard to the effect of the lyne arm angle and its effect on the spirit produced in a pot still. I have quoted the info below.
"Moreover, the design and angle of the lyne arm more or less determines the quality and intenseness of each distillate. In the lyne arm, the alcoholic vapours are led
to the cooler. The angle influences the result:
Steep ascent (+) of the vapours - The alcoholic vapours have to fight their way uphill. Therefore, they cool down slowly resulting in a very smooth and high-proof distillate.
Parallel outflow of the vapours - The alcoholic vapours almost glide to the cooler. Therefore, they cool down moderately resulting in a rather smooth distillate.
Steep descent (-) of the vapours - The alcoholic vapours rapidly fall down to the cooler. Therefore, they cool down quickly resulting in a harsh but more low-proof distillate. However, there is the risk that the “wash” unintentionally gets into the distillate. To avoid that, soap is often used to release the surface tension."
Soap!!! Any one ever tried this?????
Feed back on the info and experiences would be appreciated.
