I have pondered the very same thing.
The only issue is should you only add spirit to the point that just covers the carbon making sure all those molecules get some contact, or add more spirit but stir and shake vigorously to achieve the same effect?
The former way could prove costly, unless you were to do it in small batches and reuse the carbon say for a couple of litres of spirit.
The one advantage of the funnel method would be that you can be sure that all your alcohol is getting at least some face time with the carbon.
You have got me thinking though.Statistics: Posted by mozr — Mon Mar 05, 2012 5:51 pm
