my buddys setup has had a few batches through it no problem other than efficiency getting 125 at best proof but now last night we were running a batch and everything started comming out a transparent cloudy green only thing we did different was adding tails from last batch into it that was run 20 min before (run 2 batches of wash that are 2.5gal each) the first one went fine all nice and clear the 2nd i wouldnt even want to use as parts cleaner

i thought that but he said he had just cleaned it maybe he diddnt do it well enough though i also thought of the only other variable it was his first time using propane with it Thanks BR you the man

Most of the time Blue to Blue green or green tinted distillate is caused by excessive nutrients in the wash or a failure to clean the still properly before using it. Too many nutrients break down into ammonia which will corrode copper. Generally you see this in the beginning of the run. If you only see it in your rinse, it may be that you had some tailsy residues which sat and corroded your copper.

Do a heavy vinegar cleaning and make sure that your rinse your still out after each use. Best time to do it is when you shut down from a run. Everything is nice and hot and nothing has had a chance to oxidize. You need the copper, but you also need to keep it clean, especially if you are doing nuetrals. A little ""off taste"" can go a long way towards making a nuetral into BBQ lighter fluid.

If the collected distillate is blue, (and probably ammoniacal, but not always), the wash should be acidified!

Turbo Yeast contain a lot of nitrogen-containing compounds, and at neutral to high pH, these can liberate free ammonia. At low pH, they are bound up with the acid as salts, and do not liberate ammonia. So, by adding nutrients to an already nutrient rich turbo, you can inadvertently push the mix over the line and get ammonia with your distillate."
