Hi Adraine, it is hard to tell you what you are tasting in that beer. What yeast did you use? I have made it myself and there is a heap of crystal malt and hops and depending on the yeast, a lot different flavours and aromas will get generated and at times are a bit off - maybe, depends if you have made these types of beers before?
My approach is this. If is tastes a little funky, but not bad - then bottle / keg and see how it goes - has proven the best approach. But if it stinks like **** / vommit, and you'll know because it will make you want to do both when you smell it, then toss it.
The best approach is to take it to someone else who knows. MHB in Newcastle. I have done that and at times there are a number of really good people that will help too.
Fear.
