What is highest quality brand of essential oils?

I know that essential oils vary in quality levels. Can anyone attest to a brand that is the highest quality. I am looking specifically for grapefruit oil.What is highest quality brand of essential oils?
It's not the brand. There are lots of factors.





1. Are the oils produced where the herbs grow or are the herbs dried and shipped to the place the the essential oils are distilled. If this happens a lot of the oils are alreay gone before they essential oils are distilled. the essential oils are volatile meaning they evaporate as the plants are dried.





2. the temperature the oils are distilled at. At the proper temperatire; you get a very nice aroma. at the wrong temperature; the oil smells like turpentine





3. were the plants sprayed with insecticides, this will affect the quality of the oils





etc.





A lot of people think Young Living Oils are fabulous; but if the herbs are grown somewhere else and shipped; the quality would not be as good as they should be.





I will only give you a little advice.





1. ask if the essential oils are pure. Some companies make fragrance oils by putting some essential oil in a carrier oil such as grapeseed, jojoba, etc.





2. open the tester vial. if you like the aroma; get a bottle. If you do not like the aroma; try others.What is highest quality brand of essential oils?
Grapefruit - what a great scent! Always look for the words organic and pure. I would recommend either of the brands, Tisserand or Neals Yard. Good Luck!
