In my earlier post about the test results of a few retail essential oil samples, Janey Blaine Goude asked the question, "What exactly qualifies as a “pass” for the odor testing?"

Here's a guide for how you can improve your ability to evaluate an essential oil aroma:

Our #qualitycontrol (QC) laboratory uses a Standard Test Method (STM) for odor/aroma evaluation to ensure the testing is conducted the same way each time. A trained QC analyst uses a few key tools:

▪️ Seed to Seal Standard Ampule for that essential oil (see the attached video of our Ampulmatic that fills and seals glass ampules used to store Seed to Seal standards). Note: At home, use a #YL bottle of that oil as your standard.
▪️ Aroma Strips, dip only ~1/4" (a few millimeters) into the oil and wipe away excess oil before smelling
▪️ Coffee beans, coffee grounds, or other methods to clear the palate between samples

Use of an aroma strip is key to the evaluation process. An oil may smell different if smelling the top of a bottle (the headspace) versus an aroma strip and experiencing all of the oil constituents (not just the lighter compounds).

Another key (experienced essential oil users know this) is to allow for variability (also known as seasonal variation) since each plant harvest will smell different based on changing growing conditions (temperature, precipitation, etc.). Not every sample will match the aroma standard exactly. In fact if every batch of an essential oil smells the same EVERY SINGLE TIME, it's possible that the oil is not authentic. 

Some conditions that will cause an odor evaluation "fail":
1. Missing key aroma notes versus the standard
2. A pungent or chemical smell (acid, sour, bitter, solvent, etc.)
3. Burnt, charred or smoky smell that could be caused by too high a temperature while distilling, or distilling plant material too long

Some additional tips:
▪️ Make sure you are in a location as free as possible from other stimuli. Keep light, sound, airflow, temperature, etc. as consistent as possible.
▪️ Close your eyes and try removing other sensory stimuli  
▪️ Avoid wearing other essential oils, cologne or perfume while testing
▪️ Keep aroma testing of each sample brief to not over stimulate your senses

Does this process sound like a lot of work? Imagine conducting THOUSANDS of aroma tests like our trained Young Living QC scientists do.  That's the dedication they bring to ensuring you receive Young Living Essential Oils that meet our Seed to Seal quality commitment!
