Aussie the problem you have is what is referred to as "Huffing"
My understanding of it is that it is caused by the alcohol vapors collapsing to fast when they hit the cold condenser.
You will probably find that at the beginning of a run its not so bad or none existent, but as the run progresses it gets worse.
As the others have suggested a small amount of copper mesh or stainless scrubber stuffed up the inner tube of the condenser should help.Urrazeb wrote:The condenser needs to be hot to touch at the business end and warm at the boiler end
Gotta disagree here .....your condenser should be warm to hottish at the top and cool to cold at the bottom. Your trying to get a temperature gradient, so that the vapors don't collapse so suddenly. You can do this pretty easily by playing around with the water flow to the condenser.

:text-+1: I think that's right about the collapsing vapour where there is too steep of a temperature gradient, want a smooth change down the condenser. But I did have it back in the day on my big Liebig, and the copper mesh sorted it out.
I agree with SBB here, but I know some people run them hot. I've always run my product condensers so they are cool at the output end. Obviously reflux condensers are another story and have to be run very hot!
