The only time when taste gets in the way

Your taste should never get in the way of your tasting notes but yesterday, I couldn't get over it.

The sherry tasting turned sour and I declared aged sherry my worst Nightmare.
Aged Paolo Cortado and Oloroso smelled and tasted rotten orange and fungus.
I hope to avoid old sherry at the exam or I won't keep it academically correct.
"Those are my raw tasting notes and I stick to it Sir."
