Meanwhile, I remember a Mythbusters episode where they tested the myth that if you take cheap vodka and run it through a Brita water filter, it makes it better.

They took a bottle of cheap vodka, took a sample out, filtered the rest, took another sample and set it aside, and re-filtered the remaining vodka, and repeated this 10 times, so that they had a spectrum of vodka samples from filtered zero times to 10 times. They then brought on a vodka expert to taste test them and randomized the order of the samples to see if he could re-order them based on the number of times they went through the filter.

And he did it PERFECTLY.

IIRC, Adam and Jamie could tell the difference after 1 run through the filter, but not further runs.

I've seen a lot of videos that actually show the opposite. Even I as a non-expert over video can clearly see the difference from thousands of miles away.

The problem might just be that the TV shows you watch are so mediocre they can't even get a real expert.

Do they? Can you give an example? Because there's a recurring Epicurious series where an expert tries to determine of two samples which one is cheap and which is expensive. They're not always right but they're right quite often.

This is just your casual periodic reminder that if choosing between two possibilities, you could expect someone to be right about half the time by just guessing.

Yes yes. But the experts are consistently 90 percent plus accurate. Check out the videos! They elucidate their reasoning quite well. It's not hocus pocus

I don't know for the other, but for chocolate, price _has_ an influence on the resulting taste
