Alcohol for tincture

From a fellow grower: Should I use food grade Propylene Glycol or Everclear grain alcohol to make tincture? I had read somewhere that the propylene glycol’s effectiveness is only for a few months whereas the grain alcohol maintains its potency for several years. I don’t know if this is true or not.

For a tincture I’d use alcohol.

1 gram of flower per ounce of spirit. Freeze both in separate jars. Add alcohol to plant material (only loosely broken up to avoid releasing chlorophyll) and shake vigorously for 30 seconds. Put back in freezer and repeat shaking every 15 minutes until 1 hour has passed. Remove from freezer and strain alcohol from plant material. This will extract 99% of the available oils. Reduce until you are at desired concentration. Store in refrigerator.

Use 190 proof food grade ethanol, if possible. You can use 150 proof, too, but it has a higher water content.

Do not use PG.

What method do you recommend for reducing?

No heat. I run a fan over the tincture while it’s sitting on the workbench in the garage.

Thank you, I’ll be doing that shortly!:+1:
