Sourdough Starter Basics
You aren't making dough yet; you are cultivating a colony. The goal is to establish a rhythm where the yeast is active enough to lift bread before the acidity becomes too sharp.
Consistency is your only constraint.
The ambient temperature of your kitchen dictates the speed of fermentation. If your room is cold, expect the process to take longer.

What goes in.
- 50gwhole wheat or rye flour
- 50glukewarm water
- 50gall-purpose flour (for maintenance)
Managing the Colony
You must remove a portion of the starter before feeding to keep the volume manageable and ensure the new flour is fully colonized by the existing yeast population.
The method.
Day 1: The Initial Mix
Combine 50g whole wheat flour and 50g water in your jar. Stir until no dry streaks remain. Cover loosely and set aside at room temperature.
Day 2: The Wait
Check for small bubbles or a change in smell. If nothing happens, don't worry. Do nothing.
Day 3: The First Feeding
Discard all but 50g of the mixture. Add 50g all-purpose flour and 50g water. Stir thoroughly.
Days 4-7: The Routine
Repeat the discard and feeding process every 24 hours. The mixture will begin to rise and fall significantly once the yeast is established.
The Test
The starter is ready when it reliably doubles in volume within 4 to 6 hours of a feeding and smells pleasant and slightly tangy.
Other turns to take.
Rye Starter
Using only rye flour provides more nutrients for the yeast, leading to a faster and more robust start.
Cold Storage
Once established, keep your starter in the refrigerator and feed it once a week instead of daily.
When it doesn't go to plan.
Use a rubber band around the outside of the jar to mark the level after feeding so you can easily track the rise.
If a clear liquid forms on top, the starter is hungry; pour it off or stir it back in before feeding.
Never use chlorinated tap water if you can avoid it; filtered or bottled water is safer for the yeast.
The ones that keep coming up.
Why use whole wheat flour at the start?
Whole wheat flour contains the natural yeasts and minerals that kickstart the fermentation process much faster than refined white flour.
What does a bad starter smell like?
A healthy starter smells like yogurt or fruit. If it smells like vomit or nail polish remover, the balance is off; discard and restart.
