I do like Maha Ras, it is my favorite premade eliquid. It is entirely unique. And it was my love of it that led me to ask the maker some questions because as I started to DIY i tried to recreate it, and realized my nic, my sweetener use, wasn't as good. He gave me a little advice, not much, but enough to know that he puts quality at the forefront of his products because his answers were always about starting with reliable, quality ingredients. How to tell if your nic is fresh or old, etc... That funky taste and color gets stronger the older it gets btw.
I think if you asked Wlad from Ahlusion about how to tell if you're ordering quality products his answers would most likely be similar, although he makes flavorings as well so it's a bit different.
Did you know that there are several absinthe flavorings that are green to start with? He may be adding color for fun, or he may not be. We certainly eat a lot food coloring in our modern lives if we eat anything that is premade from a store, do you think a few drops of food coloring, which can in fact be natural, is that big of a deal? I've put food coloring in my own liquid before, just for fun, it takes a hundredth of a drop to color a tank full, there's more than that in a single piece of gum, glass of soda pop.
I'd like to add that what I'm talking about here is a comparison of say, a lot of these new, 12 dollars or more for 15 ml juices, and they're all just watermelon/kiwi, or lychee lemonade, or blueberry cookie. Go on ecigsupply and look under flavorings, you will see how absolutely un-unique these liquids are.
Amaretti cookie is a flavoring, custard is a flavoring, cream is a flavoring, butter, lemon cake, they're not making these up guys, they're just adding straight up flavoring into bases with or without sweetener then selling it to you and most of the time they're must mixing two flavors together.
Kind of like buying cupcakes at the grocery store is just paying then to do the work of using a box cake mix for you.
