One of our most common questions is about quality or spectrum of terpene blends, and it's by far the most important. Cannabis plants contain more than a hundred different chemicals responsible for their aroma and flavor, and terpenes are only a section of that.
What sets one product apart from another is the number of different ingredients in a blend, with more ingredients representing a broader spectrum. The result is that a short path/distillation cannabis-derived terpene blend will be significantly more flavorful and accurate (though containing in many cases a portion of cannabinoids), but significantly more expensive to produce. That's problematic for food/topical/vape product producers.
The answer for commercial enterprises is to derive terpenes and flavonoids from other sources that have been provided a Food Grade stamp of approval, and on a more local level source the rest of the terpenes and flavonoids from the plant material.
