' There are 2 main reasons for 'floral/chemical tasting liquid'
the short version of both goes like this:
i) shite liquid
ii) not steeped enough yet
the slightly longer version is:
i) different flavours react together in different ways. Some flavours complement and accentuate each other, some flavours cancel each other out. Because flavourings are different to natural flavours things that you think ought to go together often don't. Also too much of a flavour can also cause a 'cancelling out' kind of effect where your tastebuds taste too much of a specific flavour and get 'tired' and then stop tasting that specific flavour again. sometimes the cancelling out effect can leave a part of the intended favour behind which by itself tastes chemically or perfumy.
ii) Sometimes flavours that clash will mellow out with time. Some flavours will taste bad when frehsly mixed, but as the liquid ages the nicotine reacts with the flavours in the liquid and smooths off the rough edges and alters the flavours enough so that they complement and mix nicely rather than cancel or clash and mix badly.
If you get liquid that's not good. Leave it to steep for a couple of weeks. If after that time it still tastes bad, it's most likely just not very good.
Taste is really subjective too, so what tastes fabulous to one person can taste awful to another.'
