As far as steeping in a carto, I believe it would. I just watched a video last night and the guy has a rather complicated steeping system. He takes off the caps, stores them in the closet for 5 days. Then, he puts the cover back on for a bit and then uncovers and steeps for 2 more days... I have let most of my juices stay in their cool, dark place and they get darker and better tasting! I even got some dekang flavors that smelled very chemical like. I hated the taste, too! Soooo, I took off the cover and let them sit overnight. Still didn't like them. So, they went back into the dark box, with covers on. After a week or so, that smell went away and they started tasting better.... Not fabulous, but they went from unvapeable to vapeable!
After a certain point, if you still don't like them, they just aren't for you... I love trying new flavors, especially since I am new. I realize that there probably will be a lot of flavors that I really don't like. Another I have tried is mixing flavors. My current fave is a mix of malt, vanilla and chocolate with a hint of cinnamon to bring out the flavor. A strong flavor like a menthol or cinnamon may help mask that flavor that you don't like. Just try mixing a little so you don't waste your good stuff!
All is not lost, as you can always trade, sell or give away those juices. Lots of threads here for that, the PIF forum is excellent as are the classifieds, if you haven't checked them out yet! There is even a juice trading thread, but it doesn't get a lot of action.. Good Luck!
