Combine one pouch of Ginbrew botanicals with a 750-ml liter bottle of vodka in the mason jar.
Seal, shake, and store in a dark room-temperature place for a week. Give it another shake each day.
After a week, pour your Ginbrew through the cheesecloth to strain out the botanicals. Rinse out the jar, pour the Ginbrew back into it, and add it to your liquor collection!
