Traditional dry and curing allows for some complex sugars and chlorophyll to break down (giving a less dense flower), not sure if this is enzymatic or just a chemical process. Either way the results are flower that burns more smoothly and less chlorophylly “cut grass” taste.
It would seem a flash freeze and then dehydration would not allow this to happen. How does the flower from this cryo process smoke?
Also I have kept traditionally cured flower for years and it was fine… Maybe lost some color but still decent nose and potent.
