Cure
From Wiki Weed
The curing process is a very important step in a well-grown cannabis plant’s life cycle. After being harvested, trimmed, and sufficiently dried, the plant’s flowers are then put into airtight containers which slows the drying, allowing for a more measured and gradual process, which helps to maximize the flavor and smoke quality. Similar to what you would see with cigars or even wine, the drying and aging process develops deeper flavors and mellows the smoke. Uncured or improperly cured flowers often taste and smell like hay, burn badly, and are harsh on the throat.
