If you are creating a gin or another spirit using botanicals before or during distillation, you can set up a Botanical recipe that will pull your ingredients into the distillation.
In your Internal Spirit Type setup, select the botanical option at the far left side of the grid.
Add each of the botanical you use to create the internal spirit type with quantities for your regular batch size.
See Creating spirits using botanicals - ie. Gin for information on how to consume botanicals in a distillation run.
