I bought two similar e juices from the same company that have two different nic levels. The flavor was extremely different. I loved the first one Hazelnut Coffee 50ml at 12mg. it was great. but then I decided to try espresso by the same company. The amount of vapor was the same, but the flavor was just awful, not disgusting but almost entirely non existent. I was wondering if this is because I dropped down to 6mg of nic.
