I got a devious idea, might be worth testing, basically drink some of the expensive wine beforehand, perhaps while preparing the food for your troubles. Thereafter pour some cheaper stuff into the expensive bottle and see if anyone not party to the trick is unimpressed by the cheap wine in the expensive bottle.

I am looking to get to the validity of article quote

As a result, if we think a wine is cheap, it will taste cheap. And if we think we are tasting a grand cru, then we will taste a grand cru. Our senses are vague in their instructions, and we parse their inputs based upon whatever other knowledge we can summon to the surface.
