Why One Pass Through the Coffee Bed Is All You Need

It Smells Better Than It Taste — a quiet coffee newsletter where I share what I'm learning about coffee, curiosity, and daily rituals, this channel is an extension of that space: https://www.itsmellsbetterthanittaste.com/?utm_source=youtube&utm_medium=video&utm_campaign=9g-zw7LR2cA I have been curious about this for a few weeks. A percolator keeps cycling water through the same bed of coffee, over and over. A pour over does it once. So what happens if you take the coffee you just brewed and pour it straight back through the grounds, again and again, taking a TDS reading every time? • 20 g of lightly roasted Ethiopian white honey, 1:20 ratio, coarse grind, 190°F water, Hario V60 with a paper filter • A TDS reading after every single pass, so the extraction curve is visible rather than guessed at • Extraction went 1.22, 1.33, 1.33, 1.38, 1.36, finishing at 1.40 — climbing hard, then flattening • Past 23% extraction after the very first attempt, before any of the percolating started • The plateau shows up on the third pour and never really leaves • The cup at the end tastes like the coffee normally tastes — soft acidity, lemony, no bitterness Was this dumb? Did you learn anything? And do you have another experiment you want me to run?
