SSourdough StartStart Check
Starter + fermentation toolset

Build a healthy starter, judge fermentation better, and stop random loaf fixes.

Sourdough Start is built for the moment when a home baker asks: what should I do next — feed the jar, wait longer, change the fermentation plan, or stop making random changes?

Best first moveStart with the strongest bottleneck, not the most dramatic symptom.
Best second moveUse timing tools only after the culture is believable.
Best recovery moveUse troubleshooting to make the next bake smaller, not wilder.

Start here if…

My starter looks weak

Best when the jar is late, flat, sour, or inconsistent.

I need a feed rhythm

Best when the culture is alive but hard to read.

I need a bulk estimate

Best when the dough is already mixed and the clock feels unreliable.

My loaf failed

Best when the last bake produced too many theories and not enough clarity.

How to use the product well

Most sourdough problems get worse when the baker solves the wrong layer first.

  • Do not blame hydration when the starter is still questionable.
  • Do not blame the recipe when the room and bulk timing are clearly unstable.
  • Do not blame every failed loaf on shaping when fermentation never had a clean chance.
  • Starter firstCulture health determines whether later dough decisions will even be readable.
  • Timing secondClock and temperature should be interpreted together, not separately.
  • Failure thirdTroubleshooting is strongest when it narrows the next bake into one real test.
