How Do I Prepare My Starter for Baking? Step-by-Step Guide for Optimal Results
To get your starter ready for baking, you’ll want to feed it and let it get nice and bubbly. Just add fresh flour and water, then wait for it to double in size and show off some bubbles before mixing it into your dough.
That’s how you know the yeast is awake and ready to help your bread rise.
Try to feed your starter about 8 to 12 hours before you want to bake. This gives it plenty of time to get active.
If it doubles reliably and smells fresh with a slight tang, you’re in good shape. Keeping up a regular feeding schedule really helps.

Essential Steps to Prepare Your Starter

When you’re prepping your sourdough starter for baking, focus on feeding it well and watching for signs of activity. This helps your dough rise and brings out the best flavor and texture.
Feeding Schedule and Ratios
Feed your starter regularly—every 12 to 24 hours works for most people, but it depends on your kitchen’s temperature and how often you bake. Use equal parts flour and water by weight each time.
For example:
Ingredient | Amount |
---|---|
Starter | 50 g |
Water | 50 g |
Flour | 50 g |
You can scale up or down, but stick to that 1:1:1 ratio to keep things balanced. Feed more often in summer, less in winter.
Make sure to stir well and introduce some air.
Determining Maturity and Activity Level
A mature starter will double in size within 4 to 6 hours after feeding. You’ll see bubbles everywhere and catch a whiff of a pleasant, tangy smell.
Try the “float test”: drop a spoonful of starter into water. If it floats, it’s probably ready to go.
If it sinks, just give it a bit more time or another feeding.
Signs Your Starter Is Ready for Baking
A ready starter looks lively—bubbly, risen to its peak, maybe even with a few tiny cracks or a domed top. The smell should remind you of yogurt or fresh bread, not anything funky.
If it passes the float test and keeps doubling on schedule, you’re set. If it looks watery or has a layer of hooch on top, it needs another feeding before you bake.
Optimizing Starter Performance for Baking

If you want the best results, pay attention to your starter’s water content and the environment it hangs out in. These things really affect how active your starter gets and how your dough turns out.
Adjusting Hydration for Specific Recipes
Hydration is just the water-to-flour ratio in your starter. Most people use equal parts for 100% hydration.
Want a lighter, airier crumb? Try a higher hydration starter—with a bit more water than flour. It gives your bread a softer, open texture.
If you’re after a firmer dough, cut back the water. Lower hydration makes shaping easier and keeps things less sticky.
Keep in mind, changing hydration speeds up or slows down fermentation. More water means faster fermentation and a bit more acidity; less water slows things down.
Temperature and Environment Control
Keep your starter at room temperature, somewhere between 70°F and 75°F (21°C to 24°C). That’s the sweet spot for steady fermentation and lively activity.
If things get too chilly, your starter will slow down and might take ages to double. On the flip side, if it’s too warm, it tends to ferment way too fast and can turn out overly acidic.
Feed your starter every 12 hours while it’s at room temperature. Want to slow things down? Just pop it in the fridge and feed it less frequently.
Try to avoid sudden temperature swings. Starters seem to appreciate a stable environment, and honestly, it makes rising times a lot more predictable.
Using the same flour you plan to bake with? That can boost your starter’s performance and flavor, since it gradually adapts to whatever nutrients that flour brings source.
