Many people go by the smell to see if a lemon oil smells authentic. I aslo want to know if the lemon oil tastes like real lemon, not just smell like it. I add a drop of lemon to a cup of water. When I test a lemon oil I have ablended rind water from my Vitamix with just the rinds and water blended up. This is the only way I can how much or how far off the taste is in comparison.
I tested the rindy smelling lemon oils, the lemon drop candy smelling and also the very faint smelling oils. It was surprising to me the results I got as they were nothing what I was expecting. The constituents might change based on how teh oil was extracted but this really just affects the smell.
I urge people to not only see if they like the smell of a lemon oil but also know if they like the taste. Some oils smell more potent but they don't taste as strong. When you like the taste of an oil and you like the smell, that is a good way to know if that oil is for you or not.
