I'm a fan of peanutbutter juices, Vapor Junkie has a good one here.
The peanut butter here is indeed smooth, like the description says. It's not a pronounced peanut butter flavor, though. It's more like a peanut butter whip, quite light and there's a nice sweetness to it. The exhale has a fruitiness to it, I would say it's a light jam. I think I get grape, but it's not a super candied or koolaid grape, which is a good thing.
I like this juice, I would have preferred a stronger peanut butter flavor, but what they do have is good. It's not dry or gritty like some that I've had. I could see this being an all day vape, as it's not as rich as a lot of other juices of the same profile. It's delicate and not overly sweet.
