I use a different number of drops depending on the dropper. It took a while, but I finally figured out how all the different ones I use work. Dan's values for the numbers of drops per ml for the different brands of bottles and droppers is very accurate.
The strengths of each brand and flavor within that brand is NOT always the same. Some are very strong and some are weaker. I do find, particularly with the Perfumers Apprentice flavors that they seem stronger after they have been allowed to sit for a while. In other words, when I make a recipe and it seems perfect when fresh... it will often seem too strong after sitting for a few days. These flavors seem to develop more than the other brands and I kind of like it.
I love this recipe but it is definitely not an all day
vape for me. I have ordered the bacon from Linda but haven't received it yet. When I do I will compare it with FlavourArt's version.
