The intention of this post is not to teach but to document and provide transparency to my sourdough process. This is what works for me with my starter and in my environment.

I have successfully built and maintained a few starters using different guides but my favorite is, and my current starter is made with, the Serious Eats Sourdough Starter Recipe. What I really like about this recipe is that it only requires me to keep and feed a small amount of starter– 5g. That means I can keep my starter out on my kitchen counter without worrying about creating too much waste. Some people say that the ideal starter size is 200-25g to maintain ideal microbial health, but personally, I have not run into any issues keeping a smaller amount.
Building my starter
- Day 1 (8:30am) Combine 10g of the flour mix and 10g water (1:1 ratio). Loosely cover and let ferment for 48 hours.
- Day 3 (8:30am) Combine 10g of starter with 10g flour mix and 10g water (1:1:1 ratio). Loosely cover and let ferment for 24 hours.
- Day 4 (8:30am) Combine 10g of starter with 10g flour mix and 10g water (1:1:1 ratio). Loosely cover and let ferment for 12 hours.
- Day 4 (8:30pm) Repeat step 3 feeding at a ratio of 1:1:1. Let ferment for 12 hours.
- Day 5 -7: Repeat feeding every 12 hours (Step 3 & 4) at a feeding ratio of 1:1:1
- Day 8 – Day 13: Combine 8g of starter with 16g flour mix and 16g water (1:2:2 ratio). Feed every 12 hours at this ratio.
- Day 14+: At this point, the starter should have matured and is ready to use. Use the starter at its peak– roughly 8-12 hours after feeding. Double-check that the starter is ready to use by performing a float test by dropping a small amount of starter in water. If it floats, it is ready to use.
Maintaining my starter
After my starter has matured, I keep it on the kitchen counter and feed it twice a day at 8:30 at a 1:3:3 feeding ratio. Around this point, I slowly decrease the ratio of rye flour in the feeding mix until it is just 100% unbleached organic flour. Rye works really well in building my starter, but after my starter has matured and is healthy, it is no longer necessary to have rye. I also prefer the simplicity and cost-effectiveness of using one type of flour.
Feeding ratio every 12 hours: 1:3:3
5g starter, 15g flour, 15g water
On weeks when I am not actively using my sourdough, I would transfer my starter to the fridge 4 hours after feeding. I would let it hibernate for about 4 days before taking it out, letting it come to room temperature, and repeat the feed and hibernation process. When I am ready to use it, I wait until the second feeding to build my levain, ensuring that my starter is nice and active
Example: remove the starter from the fridge and let it come to room temperature, ~3 hours. Feed at the ratio of 1:3:3. After 12 hours, I would branch my starter into 2 builds: 1. the levain by feeding at 1:6:6 (see Sourdough Bread Process for more information) and 2. re-feed my starter at a 1:3:3 ratio. The rest is discard. I like to collect my sourdough discard and use it for yummy discard recipes, like these.
Sourdough Bread Process
My sourdough bread-making process has evolved over time but I started making sourdough bread by following the Tartine Country Bread method. I still use the same baker’s percentage for the bread ingredients but have incorporated other techniques to better fit my schedule and preferences.
Levain Build (1:6:6)
My levain build is made using a 1:6:6 ratio of sourdough starter to water and flour. This is made 8-10 hours before making the main dough.
My dough ingredients use the same Baker’s Percentage as the Tartine Country Loaf. The hydration level fluctuates depending on the type of flour and inclusions being used. My favorite hydration level in a typical white loaf is 80%.
|Ingredient||Baker’s %||Ex. Grams|
|Water||75% – 88%||225g – 258g|
I live in the San Francisco Bay Area and the temperature here is pretty mild and dry year-round. As a result, my baking schedule is very consistent. I start bulk fermentation in the morning when the average temperature is around 72F ending in the early afternoon when the temperature is about 75F. I follow that with some floor time, about 45min-1hr before retarding my dough in the fridge overnight. The total bulk fermentation averages around 6-6.5hrs and the cold retard is about 16-19hrs. The following morning is bake day. I start by preheating my dutch oven in the oven at 500F for about 30-45min. The dough is then taken out of the fridge, scored and placed immediately into the heated dutch oven. It is baked covered at 450 for at least 20 minutes and then uncovered at 450 until it is done. The typical size of my loaf is about 300g so the total bake time is about 40minutes.
Here is a rundown of what a typical baking schedule looks like for me.
Day 1: Build Levain
9:30pm: Make levain and any porridge I want to add.
Day 2: Ferment Dough
- 7:30am: Autolayse – mix flour and water together, reserving 10g of water. Set aside. Mix the reserved 10g of water with salt. set aside.
- 8:30am: Start Bulk Fermentation – add levain into flour and water. Squeeze and fold to incorporate.
- 9:00am: Add salt water mixture into the dough. Squeeze and fold to incorporate.
- 9:30am: Stretch & Fold – Take the side of the dough, stretch it up and over the top of the dough. Rotate and repeat. Do about 4-6 S&F or until the dough is tight.
- 10:00am: Laminate – Wet a work surface with a thin layer of water. Transfer the dough onto the surface and spread it thin. At this point I will add my inclusions (ex. nuts, dried fruit etc). I will laminate even when not adding inclusions, though it it not necessary, just to keep the routine. After sprinkling on the inclusions, I will fold one side of the dough over 2/3 of the dough. Like a letter. I will sprinkle some more inclusions on top of the exposed side then fold the other side of the dough over, completing the letter fold. I will sprinkle more inclusions on top of the expose side and then roll fold the dough into thirds again, completing the lamination process. The laminated dough is then placed in the container seam side down.
- 10:30am: Coil Fold – The dough at this point should look very relax. I will lift the dough from the center, stretching out one of its sides until it comes free from the container. Then I will fold the lifted center part over so now it becomes the new edge. Its like doing a letter fold by taking hold of the crease. Repeat with the other side, essentially completing the letter fold. Rotate the bowl and repeat on the other side.
- 11:00am: Coil Fold – The dough should be relaxed again at this point so I will repeat the coil fold.
- 11:45am: Coil Fold – The dough should be relaxed again at this point so I will repeat the coil fold.
- 12:45pm: Coil Fold – The dough should be relaxed again at this point so I will repeat the coil fold. This is the last coil fold.
- 1:45pm: Shape – lightly dust a banneton or proofing towel with 1:1 flour and rice flour. The rice flour helps prevent sticking. Now dust your work surface and the top of the dough with flour. Turn the proofing container upside down onto the work surface. The dough should come free. Take the left side of the dough between your fingers and stretch it out and then over the center, like a letter fold. Lightly press the the edges into the center. Repeat with the right side, completing the letter fold. The dough sound look rounded, like a log. Now take the top of the dough and fold it over the center, lightly pressing the edges down. Roll the rest of the dough over, swiss roll style until the seam is at the bottom. Pinch the edges closed and tuck them under the dough. Using a bench scraper, flip the dough from the work surface into your hands, seam side up and place it in the banneton. Cover and let the dough rest for 1 hour.
- 3:00pm: End Bulk Fermentation: ~6.5 hours. Put the dough into the fridge to retard ~16-19 hours.
Day 3: Bake
- 9:00am: Preheat the oven to 500F. Place the dutch oven inside.
- 9:40am: Take a parchment paper and cut the corners out. This helps with putting the sourdough into the dutch oven. Flip your dough out from the proofing basket. Score and lightly spray with water from a spray bottle. Take the dutch oven out of the oven and remove the lid. List the dough by the ends of the parchment paper and place it inside the dutch oven. Put the lid back on and transfer the dutch oven to the oven. Reduce the oven temperature to 450F.
- 10:00am: Take the dutch oven out and remove the lid. Marvel at your work and transfer it back to the oven.
- 10:30am: Finish Bake. Remove the sourdough and let it cool for about an hour before slicing.
