You are tasting yeast in an active stage - it won't taste very pleasant.Since I had to dump it, there is alot of trub. Good news is that this fermenter has a trub dump at bottom. I will wait a couple more days to start dumping. I just took another try and it is amazing how much the taste has changed for the better. However, no way will this beer be at its best when done. Just too hot for too long.
You should wait 8-10 days before taking your first sample. Even after 8 days, if there is still a lot of yeast in suspension it will most likely not taste as expected (yeast strain dependent to some degree). If your fermenter is clear then simply wait until the beer starts to clear and the yeast drops out of suspension before taking your next sample.
"However, no way will this beer be at its best when done. Just too hot for too long." - as others have stated: as long as you didn't pitch the yeast while it was still hot or leave it open to potential wild yeasts then you are fine. I've waited hours before pitching - no big deal. Many will wait overnight to allow a gradual cool down - again, fine.
Give it time - Often easier said than done. -
