James Hoffman just released a 2nd Aeropress
video on optimal brewing technique that provides great information for Aeropress users, but is just as instructive on
the benefits and execution objective blind testing. He uses a triplet technique I had not seen before. At the 22 minute mark his results in 1 test were different than expected, and he discusses confirmation bias. (See post #430 for the first video).

Wonderful. I think this will be an iconic video in Aeropress folklore in years to come. You've addressed nearly all of the myths surrounding the Aeropress in a systematic way.

You're turning my world on its head, James. Rinsing the paper doesn't matter. Blooming or not doesn't matter. Inverted or not doesn't matter. Going down to the hiss or not doesn't matter. Popular internet coffee wisdom has led me astray up until this point and I'm shook.**
So, it appears blind testing kills popular misconceptions in coffee brewing just as in audio. Perhaps because only the technique is changing here (rather than investing in expensive new stuff and then discovering that does not work) the comments seem a lot more rational than one gets in audio.
Does blind testing have greater acceptance in coffee than in audio overall?

2 minute steeping time, swirling before extracting, and starting with boiling hot water, do matter.
