Clouds Of Vapor ButterScotch

Update: It contains diacetyl which is not good stuff. It is supposed to be a small amount but I am taking it off my current favorite list until I find out more. Here is the update post.
COV Butterscotch is amazing. If you have not tried it then try it. Don't be put off by the organic tittle. It is strong like nothing else. The taste is great. The smell lingers on you. An the flavor last to the last drop is vaporized. This is what I want ejuice to taste like. Sadly most ejuice out there is not like this great flavor.

I am running low on my bottle, COV does not have sampler packs and I heard not to buy juice from hardware sellers. So, I went through a lot of ejuice over 100 before I tried COV Butterscotch. I tried it because it was mentioned as being great on the vaporcast. Hear most of the juice is flavoring, instead of 20 percent in most juices. I am glad it is if that is true.

COV has amazing customer service and the juice I tried was mind blowing.

I am vaping it on a darwin. So let me tell you how it taste at different watt settings
You can use OHMs Law to figure out my impression of the flavor with different voltage and atomizers if you don't have a darwin.

At 4.2 watts the juice tastes sweet and still has amazing vapor production
At 9.0 watts the juice is not as sweet better vapor production ]
At 11.0 watts the vapor is amazing not sweet but the rest of the flavor is there
At 12.7 watts the vapor is the even better. The flavor still exist but is not sweet at all. It taste kind of peaty.
Taste a bit like a good scotch. Here is the wiki on peat if you are not familiar with the word. http://en.wikipedia.org/wiki/Peat

I know taste is very subjective but strength and if the flavor has nut taste is not as much. I am not a big flavor of butterscotch fan but this juice is a must try IMHO.

Can anyone recommend a juice this strong in flavor?
