I'm new to Vermillion and I have only tried the K-Max so far but some thoughts...
I've had it for about 5 or 6 days and let it steep til yesterday. At first it reminded me a lot of BWB's Malty Toffee mixed with a good standard tobacco type of flavor with a lot of maybe vanilla and some caramel.
But it seems to be more complex then that and has some spiciness to it.
It's relatively sweet. A lot sweeter then I thought it would be.
It gives a little reminder of a RY4 or 555 even.
But it also has this flavor on the back end that I just can't put my finger on. It's really good though, but I for the life of me can't come to a conclusion what it is, it's like it's changing as your exhaling.
Overall I don't think I could ADV this, because I'm not super into sweet flavors, but that's not to say it's a bad juice. In fact it's the opposite, it's a rather fantastic juice. Really well down. It's pretty complex and yet not overly. It's something I can see trying to keep in my collection and using on the semi-regular, but just not as one of my main ADV's.
I still have the Minnesota Menthol and Kentucky Cherrywood to try, but I'm out of fresh carts damn it haha.
Definitely satisfied and impressed with K-Max even if it isn't exactly what I was expecting, I'd definitely recommend it.
