My setup doesn't do that. I have an eGo twist, currently on 3.6volts and the clearomizer I'm using is about 2ohms. It's not too hot.
Another couple of things to consider:
-Maybe the liquid needs steeping
-It very well could be a bad batch, If you think it may be contact the company and just explain how it tastes strongly of pepper.
-How old is the coil in your clearomizer? Could it be time to replace?
I try not to write bad reviews of companies until I am sure it is just the companies fault. I would feel bad if I really just didnt like a flavor and wrote a terrible review cause of that. I like to think customer reviews are very important to a company.
If I got something from a bad batch I would just tell the company the flavor was bad and see if they are willing to help in any way.
However If I got leaking, poorly packed bottles, sent an email, and they pretty much told me in a decently kind way to shove it. I would leave a bad review.
