I did a test comparing tapping, doing nothing, and OCD-ing. We measured TDS and tasted everything blind.
Tapping tasted best every time.
Doing nothing tasted awful.
OCD tasted better than nothing, but there was obvious unevenness.
I want to test more, but haven’t had the time. I’m truly sceptical as to wether it can achieve better results than tapping. Maybe it could achieve parity if the coffee was well distributed before using the tool, but doesn’t that defeat the purpose??
