What you have tasted is a combination of 'green' i.e unconditioned beer, and yeast since your brew has yet to clear.
Patience is a friend of the homebrewer. After the two weeks or so in the FV you have to wait, again :-(, for another one or two weeks for your beer to carbonate after priming, and then, yet again :-( :-(, another two weeks in the cool to condition. You can then 'sample'. Depending on what you have brewed you may be able to start drinking it then, but most beers do improve with keeping. Hopefully your patience will rewarded and you will be more than happy with the result of your first brew. :thumb:
