I love exploring essential oil chemistry!
We can break down essential oil chemistry to see the precise components in each oil with GC/MS testing (Gas Chromatography/Mass Spectrometry). Seeing the GC/MS report for each new batch of essential oil is always exciting! Even the same plant growing in the same area can produce a different essential oil year to year depending on factors such as the weather, when the plant was harvested, and how the oil was extracted.
This means the chemical component percentages might change, and the aroma of the oil could be different. Personally, I find that fascinating! I’m not creating products that need to be exactly the same every time I make them, so the variation intrigues me.
Have you noticed variations in aroma when you buy essential oils year to year?
