Espresso Dial-In Assistant cover

One shot, one change, and the reason.

Dialing in is not hard; it is just easy to change three things at once and learn nothing. This holds you to one change per shot and tells you which one.

WHAT IT DOES

  • Ratio, flow rate and, with a refractometer, extraction yield (TDS × yield ÷ dose)
  • The next change, in the order that works: grind fixes time, ratio fixes taste, temperature last
  • Reads your taste and body notes with the numbers: "sour and fast" is not the same fix as "sour with good time"
  • Brewing control chart: every shot plotted by strength and extraction, with the sour, bitter and ideal zones drawn in
  • Shot log per bag with a time-versus-grind chart, and a recipe card from your last balanced shot
  • Bag tracking: roast date, rest window, days off roast, with too-fresh and stale warnings

Who it's for

Home espresso people who open a new bag every couple of weeks and are tired of wasting the first quarter of it.

Espresso Dial-In Assistant

one shot, one change, and the reason, with a log per bag

Dose, yield, time and what it tasted like in. Out comes the single adjustment for the next shot (grind, ratio or temperature, in the right order), the extraction yield if you own a refractometer, a brewing control chart of every shot, and a recipe card per bag that writes itself as you log. Bean freshness is tracked too, so it knows when the bag is too fresh to judge or too old to bother.
