How to proof down alcohol

[@MrShytown77]

I would say you can go higher than 40% on a run as long as you don’t have an open flame 🔥.. second runs should probably be done in those electric side heating stills.. what are your thoughts?

[@fredwilliams420]

40% ABV is the absolute lowest percentage a liquid can be, and still be flammable... below that, fire behaves as if it's water

[@jims1995]

The combustion point for alcohol is 40% in ABV, it will burn

[@PoppaLongroach]

I use the tails to proof mine down and the rest of the tails go into the thumper. I don't waste anything.

My barrel is 117 but I wanna get to 45/90

Proofing/Dilution Formula:
Alcohol meter reading ABV divided by desired ABV multiplied by amount of distillate minus the amount of distillate = amount of water/tails needed for dilution.
ABV in mash/wash calculation formula for hydrometers and refractometers:
Original Gravity minus Final Gravity multiplied by 131.25 = ABV% in mash/wash
Specific Gravity forumla for refracometers using Brix:
Brix units mulitplied by 4 = specific gravity reading.

Nice info. Thanks for sharing brother.

[@AdThat]

@stillintheclear do you add the water to proof down gradually? Or all at once? I’ve seen so much mixed information about shocking the spirit

[@StillnTheClear]

I do it all at once and have never had a problem.

[@howlingmedia4354]

45 V/90%

[@wait4dl]

could you make it harder?

[@Goibniu001]

Yes, the "40% max rule" is because of the fire-hazard issue, as you said.
Reason: Alcohol is flammable at 50% (100 proof.)

[@PsychoticEGG]

I've lit 40% abv vodka on fire. It's still flammable at 40%. Though less stable.

[@be-you-tifulwithcheridan8231]

Great information!

[@StillnTheClear]

Thank you.

[@Platypus2012]

It's because the flame of pure alcohol is invisible.

[@joshbooker9473]

Thought me what I needed to no

[@sandman0917]

I'm 420!

[@cezarbutwyper]

40% doesn’t burn

5 minutes of gum bumping before getting to the point of the vid that is only 8 minutes long. SMH
