I have some problem with my result today, so far I had multiple runs (~10) and it went okay until the previous one and current one.
I tried couple of new method and now I'm getting blue distilled alcohol.
These are what I used
6 kg of sugar
Still spirit turbo yeast
Carbon
Carbon clear
no DAP no Baking soda
I have used my own still,
5 Gallon ss pot with copper condenser.
I'm using my cooktop as heat source - not delicate control, but able to get 94% with triple distillations
Previously I have not used anything else but sugar and turbo yeast, but from previous run, I decide to try new method
First, add carbon and carbon clear on the process
second, add copper chips inside the boiler since I heard the copper reduce the oder of Sulfer - have 25 of copper pipe fitting part inside of the boiler.
I saw from parent site,
so I checked my mesh ph level, and it is little under 6.0 - so do I need to make it more acidic?In fact, I've learned that it is just the opposite! Acid washes do not corrode the condenser (unless, perhaps, they've been allowed to sit far to long and have gone acetic), but neutral to alkaline ones DO. Heating an ALKALINE wash, particularly one with lots of nitrogen-containing compounds that have been put in as nutrients, liberates ammonia, which corrodes the heck out of reflux coils and dyes the distillate a distinct greenish blue.
The Upshot: if the WASH is turning blue, it's probably due to acid wash corroding a copper sheathed element or a copper boiler, but if the collected DISTILLATE is blue, (and probably ammoniacal, but not always), the wash should be acidified!
Turbos 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.
I don't think my problem is the nutrient issue, since I never had the same problem before....
If you guys have any experience or thought about this, please share with me.
