Making tinctures isn’t difficult, but it can take a couple of weeks.
Mix cannabis and high-proof ethyl alcohol in a jar, then seal it and put it in a freezer. It can soak anywhere from a week to six months, but the jar will need to be shaken for one minute each day to keep the cannabinoids evenly distributed.
To finish the process, filter out the cannabis plant matter from the remaining tincture liquid using the coffee filter.
The tincture will be usable for years if kept in a cool, dry place out of direct light.
