I'm newer to vaping, so I haven't really tried a wide selection yet, plus I researched first to find a vendor with great reviews before shopping and I've had great luck. But, I did get a few that were not really my tasting type, whether too much sweetly or not strong enough on throat hit, none are too terrible that I won't be able to eventually use them.
Pretty much I just sneak them in by only a few drops here and there in-between filling the tanks with one I do love. So, I only have to put up with the taste of them for a few vapes, not for any great length of time.
I like the ideas being offered here though, for if I do end up with a nasty flavor juice. Giving them to a new beginner and the steeping process sounds good to me.
