Refining lentil
An alembic accessory placed between the vapour chamber of the alembic and the swan neck pipe. Its main purpose is to save time as the distiller has no need to proceed with a second distillation process to obtain higher levels of alcohol in the final distillate. The refining lentil carries out an initial condensation of vapors as heavier (less volatile) substances drop back into the still pot thus only allowing lighter vapours (higher alcohol concentration) to pass through to the water cooled coils in the condenser.
