What do you think contributes to the amount of harshness of an e-liquid?

So today I was going back and forth between two different e-liquids. Liquid A (fresh mint for your information) is ridiculously "smooth" and there is no harsh feel to it. Liquid B (mango) has a harshness to it. The mango flavor tastes good, but there is a slight rough feel that I get when vaping it.

Both are 18 mg/ml and are the same nicotine strength. So, it's not that.

Both are also from the same manufacturer.


Your thoughts and experiences?

pg/vg ratio, wicking issues, resistance of atty, power used to vaporize, a lot of flavors have differing vape properties based on power used.
The flavorings themselves can cause harshness.
