Activated Carbon


Recommended Posts

Quick question, I realize that proper distillation, etc. means activated carbon is not required. However, I have tried using carbon and wetted my carbon and have noticed something that has me scratching my head. If I put in 100 proof in at one end using a system with 2 4ft, 4" diameter stainless tubes I get 60 proof out of the other end. Any ideas or insight would be greatly appreciated. Thanks.

You are likely diluting the spirit with the water wetting the carbon being displaced, especially if you are running in batches. The procedure I have heard is to run "storage" alcohol through the filter tube after wetting, and measureing the output until it reaches your input proof, meaning all the water has been displaced by alcohol. Once you proof is back up, separate that first collection for storing the filter after you complete the run, then proceed with your standard product filtration. I am still new to carbon myself, but this seems to be the likely culprit; hopefully others more knowledgable will hopefully chime it...
