I understand that you folks that know what you're doing often add high proof white liquor to lure to prevent mold and to provide evaporative lift. I'm wondering how much you add roughly percentage wise. I'm working with 190 proof everclear. Thank you for looking.

I should add that I'm making a castor based beaver lure.

Big Sam, I have only worked with green or semi dried castors. Cut into pieces then ground into a paste. Then used Methyl Paraben to prevent mold. For preserving the castors use Zinc Valerate or Sodium Benzoate.

I believe the alcohol is mainly used as a Tincturing Agent, with a few possible side benefits. Also, I believe Paul, uses alcohol to prevent mold in his dried castors.

Hopefully, this is a start to answering your question?

Thank you Mark. That gives me information I didn't have before. I appreciate it.

Big Sam every year i make a batch using a fall spice wine i dry the castors then place them in a clean mason jar and cover with the wine to this i add a bit of PGA or good shine i shake this up once a week and let go for at least 6 months(a year is better)
then strain the liquid and grind 2x then add glycerin to freeze proof this is an incredible way to get a sweet castor smell
to the left over tincture i will add 2x the amount of glycerin so if you have 8oz of tincture i add 16oz of glycerin to that this makes an excellent mixing ingredient to add to your baits/lures

Thank you, Bob. Much appreciated.
