cup of cough syrup is a pretty good sized dose.
especially with the grain base. lol
Some places don’t allow sales of 180 proof but OR does, I use for tinctures and cough syrup. One cup 180 proof isn’t that much when the total volume (of last batch) was 1 3/4 gallons total cough syrup. I roughly figured it to be 10% alcohol per dose; so for I teaspoon or tablespoon, not that much. This syrup no one could or would want to drink a cup of!
