Definitely shoot them an email, I too asked about there PG, VG, and Nic. He was saying how all the ingredients are 99.9% pure and how even getting 99.5% makes a negative impact on eliquid. He said he gets his nic from "xtreme"...I believe that was the name. If you shoot him an email he will definitely be able to answer more efficiently then I lol. Here's what I can tell you FOR SURE, I vape 12mg and there are some companies that TEAR my throat up even at 12mg. One in particular has excusing admitted on the forums that they don't have the best nic, and that happens to be the company that tears my throat up. With KBV, I also ordered 12mg and it was SOOOOO smooth. You can feel that you were inhaling something, yet it was just......smooth. I have ordered from dozens and dozens of vendors, and I can honestly say that after my experience I'm stopping at KBV. I'm tired of wasting my money on junk liquid. As for the cappuccino, I bet they can make it. In something I was readin on there site it said if there's a certain flavor you want let us know and we'll do our best to make it. But def give them a try, I don't think you'll be disappointed
