Did you taste the sample warm and then drink the wine after it had been chilled?
I made a batch of mead that tasted great in the fermenter and when at room temp, but when i opened the first bottle (that was chilled) it was awful! I let it warm back up to room temp and it was fine again. If this is the case, just give it some age for it to settle out
