Hello from Washington State in Welcome & Introduce Yourself Posted March 31 I wish you the best of luck on your journey. There are only two companies in the USA that make continuous columns. One of them has been making the same model (construction) for 100 years already Only different sizes I see that the alcohol and whiskey industry is very conservative. Everyone is satisfied with the "big shining tanks" of steel and copper. Nobody thinks that you can get three times the distillation rate from the same place in the room.
