Level Up Your Dough Game: The San Francisco Starter Playbook
So, you snagged yourself a piece of the good life—a San Francisco Sourdough Starter, the OG of tangy, bubbly goodness. This isn't just flour and water, folks. This is a living, breathing legend, a relic from the Gold Rush days when miners kept their 'sourdough' safe like precious gold. You've got a starter with a direct line to the special bacteria, Lactobacillus sanfranciscensis, that makes that iconic San Fran tang.
But now what? Don't sweat it. Taking care of this pet microbe is easier than keeping up with the Kardashians. You just gotta know the routine. Let's roll up those sleeves and get this "Hooch-Master" or "Dough-Biden" (yeah, people name these things) ready to bake some epic bread!
Step 1: Wake Up Your Sleeping Giant (The 'Feed Me, Seymour!' Moment)
If your starter, let's call him "Frannie," came straight out of the fridge, she's probably feeling a little sluggish—like she just pulled an all-nighter. She needs a proper wake-up call, and that means a snack.

| How To Use San Francisco Sourdough Starter |
1.1 The Great Discard
First things first: we gotta make room for the fresh stuff. This is the part where you toss some of your starter out. Don't clutch your pearls! It feels wasteful, but it's crucial to keep your starter strong and stop it from growing into a mountain of gooey potential.
Toss or Use: Grab your jar. Scoop out and discard (or use for a 'discard recipe' like pancakes—google it, it's a game-changer) most of your starter, leaving behind about a quarter cup (around 50-100 grams). This is the small part that carries the torch of life.
Hooch Check: See a grey or dark liquid on top? That’s "hooch," which is just the boozy byproduct of a hungry starter. You can pour it off (for a milder taste) or stir it right back in (for a tangier, bolder flavor).
1.2 The All-You-Can-Eat Buffet
Now for the feeding—this is where you give Frannie the fuel to rise like a true champion. We're going for a 1:1:1 ratio by weight. Get yourself a kitchen scale, because we're being precise, not "vibing" it.
Ingredients: Equal parts (by weight!) of:
Leftover Starter (e.g., 50g)
Lukewarm Water (e.g., 50g) – Use filtered water if your tap water is heavy on the chlorine. Chlorine is a microbe buzzkill.
Flour (e.g., 50g) – Unbleached bread flour or all-purpose works best for a San Fran style.
Mix It Up: Stir it all together in a clean, clear jar until there are no dry pockets of flour left. It should look like a thick, lump-free batter—think viscous, but not cement.
Mark and Wait: Use a rubber band or dry-erase marker to mark the starting level on the jar. This is your personal rise-o-meter. Cover the jar loosely (a lid placed gently, a coffee filter, or a paper towel—it needs to breathe!) and set it aside in a nice, warm spot (ideally 70-75°F/21-24°C).
Tip: Focus on sections most relevant to you.
Step 2: Hitting the 'Sweet Spot' (Peak Performance)
Your starter is officially "active" when it has doubled (or nearly doubled!) in size and is full of bubbles. This is the golden window—the moment of maximum yeasty power—and when you want to use it for baking.
2.1 The Float Test (The Ultimate Vibe Check)
Want to know if your starter is truly ready to rock? Time for the "Float Test."
Gently scoop a teaspoon of the bubbly, peak starter.
Drop it into a glass of room-temperature water.
If it floats: DING DING DING! You’ve got a winner. The trapped gas means it's light, airy, and powerful. Get baking!
If it sinks: It's either not quite at its peak yet, or it's past its peak and crashing (hungry again!). Give it a little more time, or if it's already fallen, just feed it again. No biggie.
2.2 Time It Right, Baker
Depending on the temperature of your kitchen, the rise could take anywhere from 4 to 12 hours after feeding. Keep your eyes peeled for that domed top and lots of bubbles. Once you see it, that's your cue. Use what you need for your recipe, and then move on to Step 3 with the leftovers.
Step 3: Settling Down (The Maintenance Phase)
Once the bread is in the oven (or proofing), you need to take care of the "leftovers."
Tip: Skim only after you’ve read fully once.
3.1 The Fridge Life (The Long Nap)
If you’re a casual baker—say, once a week or less—the fridge is your best friend. Cold temps slow down the party, so Frannie won't get hungry so fast.

Clean and Store: After you’ve baked and used the amount your recipe called for, feed the remaining starter with your usual 1:1:1 ratio. Let it sit at room temperature for about 1-2 hours to get a little jump-start, then put a tight lid on it and stick it in the fridge.
Weekly Check-in: You need to feed this cold starter at least once a week to keep her happy. If you go longer, you risk running into a starvation situation (more hooch, an acetone-like smell). Just pull her out, feed her (discarding most first!), let her sit for an hour or two, and put her back.
3.2 Counter Culture (The Daily Grind)
If you're a bread fiend and baking every day, keep your starter at room temperature. This means feeding her once or twice a day to keep her at peak performance. It’s a commitment, but you'll have fresh bread on demand! Just repeat Step 1 religiously.
*Pro Tip: You are the Master of your 'Dough-main.' Adjust the feeding ratio to slow things down. A 1:2:2 ratio (1 part starter to 2 parts flour and 2 parts water) will take longer to eat through the food, meaning less frantic feeding!
FAQ Questions and Answers
How to Tell If My San Francisco Starter is Bad?
If you see pink, orange, or black mold, it’s a goner. A dark layer of hooch or a strong acetone (nail polish remover) smell means it’s starving, but it's usually fixable with a couple of consistent feedings.
Tip: Pause if your attention drifts.
What is Sourdough 'Hooch' and Should I Pour It Off?
Hooch is a layer of alcohol that forms when the yeast gets hungry. You can pour it off (less tangy bread) or stir it in (more tangy, bolder flavor). It's totally safe either way.
How Do I Make My Sourdough Bread More Sour?
To amp up the San Fran tang, try feeding with cooler water (around 68°F/20°C) or using a lower feeding ratio (e.g., 1:2:2). This encourages the lactic acid bacteria responsible for the sour kick.
Why Isn't My Starter Rising After Feeding?
Your starter might be cold, using chlorinated water, or it might just be a little weak. Try moving it to a warmer spot and ensure you're using filtered water and good quality flour. Consistency is key.
Can I Use Different Types of Flour to Feed My Starter?
Absolutely. All-purpose or bread flour is standard, but you can try rye or whole wheat for a boost of nutrients and a different flavor profile. Just stick to unbleached flour.
Tip: Take mental snapshots of important details.
How to Use Sourdough Discard in Recipes?
Sourdough discard is the unfed, un-bubbly portion. Use it in recipes like pancakes, waffles, crackers, or muffins. It adds a slight tang without being the main leavening agent.
How to Rehydrate a Dried Sourdough Starter?
Mix the dried starter with equal parts water and flour by weight. Let it sit at room temp for 12-24 hours. Once you see bubbles, start a normal 1:1:1 feeding until it's doubling consistently.
What is the Best Jar to Store My Sourdough Starter In?
A clear, straight-sided glass jar is the gold standard. The straight sides make it easy to measure the rise, and clear glass helps you check for activity and cleanliness.
How to Transport My Sourdough Starter When Traveling?
You can take it on a trip by feeding it a stiff, low-hydration ratio (more flour, less water) and placing it in a well-sealed container. It'll stay dormant longer. Or, just dry some out!
How to Know When the Starter Has Reached its Peak?
It will have visibly doubled in size, have a domed top, be full of bubbles, and smell pleasantly tangy (not strongly of acetone). You should use it right before it starts to fall back down.
