Live-resin extractions are concentrates made from entire plants that are cryogenically frozen soon after harvesting. Curing is the process of slowly drying out a bud to preserve as many of the oils, cannabinoids and terpenes (the things that give bud flavor) as possible. But a lot gets lost during curing. The freezing process preserves more of the oils and terpenes that are present in the plant when it is alive and allows for them to be extracted into the finished product. When done right, this results in the most full-flavored, complex concentrates around.
