Step 5: filtration
When your pure-ish alcohol from your braga has been distilled the first time, you have to filter it.
Take natural wood charcoal (without lighter fluid), grind it into a powder, and place it into a bottle with you samogon. Close the lid and start shaking the bottle. when afterwards take a clothe or bangage and filter the concotion ( this is just to keep your still clean) and pour it back into the kettle. Repeat the distilation process.
For really pure alcohol you ned to do the distilation and filtration process 3-4 times.
