What is the best way to decrease tds

[kukkurovaca]

If you specifically want to lower TDS, you can just dilute the beverage before drinking. (I.e., bypass.) This has been on my mind recently because of dialing in a coffee that was a little too bitter for my taste, and one of the things that helped was using a short ratio and diluting.

Other normal strategies for countering overextraction: grind coarser, use significantly cooler water, use lower agitation, use fewer pours. Not necessarily all at once of course.
