Look, my coffee routine is _perfectly reasonable_.

Fractional gram dosing, multiple pours at different temperatures, timed switch from immersion to percolation, and benchmarking different filter papers has a _measurable impact_ on my coffee.

And I have the data and refractometry measurement data to show it.

... Admittedly the refractometer was expensive, and incorporating it into the routine is complex and not very intuitive.

I can also assure you that I don't look cool while doing it.

You can buy cold brew coffee at Costco in bulk in cans. Just throw some in the fridge.

You poke fun at it, but great irony is that a lot of knowledgeable coffee people started poking at all the techniques recently and we've learned that almost everything towards the showy complicated side of it are completely not worth thinking about or will have worse results. Osmotic pouring looks neat but will underextract anything that isn't dark. 4:6 is still questionable over most simpler 1-2 pour techniques. That showy thing of raising the kettle up and down a lot also will underextract.

Pretension is nine tenths of the law
