I'm giving a 9/10, however I'd rate it a 9.5/10 if I could. It's such a smooth, satisfying juice that very much so lives up to it's name. My ADV is Demon Energy by Mt. Baker Vapor. I prefer citrusy/fruity juice, so this why I didn't rate a 10. I wouldn't say there's no better juice, but it's certainly great. I wanted a dessert, chocolatey juice that I could vape every once in awhile. My all time favorite candy is a Reese's peanut butter cup and after reading rave reviews about Keystone's PBC, I decided to take the plunge and order a 30ML bottle.
This absolutely is what I was looking for. It tastes a little more peanut butter than chocolate, but I actually prefer it this way. It's absolutely worthy of carrying the Peanut Butter Cup name. I'm vaping at about 16 watts on a mech, and this is very flavorful. I'm more about flavor than producing clouds, but it does produce a nice thick, very pleasant smelling cloud. I'm thoroughly enjoying every bit of it and would recommend anyone who loves Peanut Butter Cups to give it a try. I won't vape it all the time, but it will definitely be a nice treat. I'm very glad I decided to order a 30ML. It's a little expensive compared to MBV, but I would say it's more of a gourmet flavor and will satisfy my vaping sweet tooth. This is exactly what I ordered it for.
I should note that I did not steep it, as I was too excited to try it, however I can imagine it'll only taste better as time goes on.
I ordered on a Thursday and received on a Monday from PA to IA. Received a hand written note from Zach at Keystone requesting a review. I think this is fantastic and shows they really care by making the whole purchase a little more personal.
