Perfume blotters are also known as smelling strips.Inhale deeply and study the aroma from the blotter immediately, then again after a few minutes, 30 minutes, several hours, next morning, and throughout the day, until there is no noticeable fragrance. Take notes at all stages of the evaporation process. How would you describe the aroma in terms of scent, shape, personality? How does the aroma change over time? How does the aroma move? How do you experience the aroma mentally, emotionally, physically? How does the essential oil look on the blotter strip? Does it change over time? How does the essential oil move on the blotter strip? Note when essential oils have a high terpene content the lighter notes tend to run up the blotter while the denser aroma molecules remain at the end where the blotter was dipped in the oil or the oils were dropped on the blotter. You want to use all your senses to assess an essential oil in your organoleptic evaluation. You can apply a small amount of the essential oil (1 drop or less) on the tip of your finger, and rub your fingers together. How does the essential oil feel?
Also, if you desire to, you can touch the blotter strip or your fingertip to the tip of your tongue to taste the essential oil. How would you describe the taste?
Be sure to keep notes on all aspects and stages of your organoleptic evaluation, and write a description of your findings.
