Infusion is a chemical process that uses botanicals (typically dried herbs, flowers or berries) that are volatile and release their active ingredients readily in water, oil, or alcohol. In this process, a liquid is typically boiled (or brought to another appropriate temperature) and poured over the herb. After the herb has been allowed to steep in the liquid for an appropriate period of time, it is removed (possibly by straining) leaving "an infusion". Unless the infusion is to be consumed immediately, it is bottled and refrigerated for future use.
