Hearth and Banter Bakery: Your Sourdough FAQ (From One Flour-Covered Friend to Another)

Welcome to Hearth and Banter Bakery, where we believe every loaf has a story — and a few plot twists along the way. If you've ever stared at your starter wondering if it's actually alive, or pulled a super-dense loaf out of the oven and wanted to cry into your crumb, you're in the right place. Here are friendly, judgment-free answers to the sourdough questions bakers ask me all the time.

1. Why isn't my starter active or rising?

First, take a deep breath. A sluggish starter doesn't mean you've failed; it usually just means it needs more time, warmth, or food. Starters are living communities of yeast and bacteria, and they don't all wake up at the same speed.

Here are a few things to check:

• Temperature: Starters love cozy temps. Aim for around 75–78°F (24–26°C). If your kitchen is cooler, it will just take longer. Try a warm spot like on top of the fridge or near (not on) the stove.
• Feeding schedule: In the early days, feed consistently (every 12–24 hours). If you skip feeds or change the routine a lot, your starter will be confused and slow.
• Flour choice: Whole grain flour (like whole wheat or rye) can give your starter a boost because it has more nutrients and wild yeast.
• Time: New starters can take 7–14 days (sometimes more) to become reliably active. Early bubbles can be fake-outs. Keep going.

If it smells pleasantly tangy, shows some bubbles, and slowly rises and falls, it's probably fine—just moving at its own pace.

2. How do I know when my starter is ready to use?

Think of a ready starter like a friend who's had just the right amount of coffee: energized, not chaotic. You want it at or near its peak of activity when you mix your dough.

Signs your starter is ready:

• It has doubled (or nearly doubled) in volume within 4–8 hours of feeding, depending on temperature.
• The texture is airy and bubbly, not runny or paste-like.
• The smell is pleasantly yeasty, fruity, or tangy, not harshly acidic, cheesy, or like nail polish remover.
• The “float test” sometimes helps: a spoonful of starter gently dropped into water may float when it's very airy. If it sinks, don't panic—the float test isn't perfect, but it can be a helpful clue.

The biggest test is consistency: if your starter rises and falls on a predictable schedule after feedings, you're ready to bake.

3. Can I use all-purpose flour instead of bread flour?

Yes, you can! Bread flour has more protein than all-purpose which makes for a stronger dough, but whichever one you prefer works perfectly fine. There are no set rules on flour — use what you have and what you love!

4. What does bulk fermentation mean and how long should it take?

Bulk fermentation (often just called “bulk”) is the first long rest your dough takes after you mix everything together. During this time, the yeast and bacteria in your starter are eating, producing gas, and developing flavor. The dough relaxes, strengthens, and starts to puff up.

How long it takes depends on:

• Temperature: Warmer kitchens = faster fermentation. Cooler = slower.
• Starter strength: A very active starter works faster than a sleepy one.
• Dough hydration and flour type: Wetter doughs and whole grains often ferment faster.

As a rough starting point, at room temperature you're often looking at 3–6 hours. But instead of watching the clock only, start training yourself to watch the dough (we'll talk about that in the next question).

5. How do I know when bulk fermentation is done?

This is one of the trickiest skills in sourdough, and it takes practice. Your dough is “done with bulk” when it has gained enough gas and strength, but isn't collapsing or over-proofed.

Look for these signs:

• Volume: The dough has increased by about 50–75% (not always a full double, especially with lower hydration or lots of whole grain).
• Surface: It looks smoother, slightly domed, and may have some bubbles on top or along the sides of the bowl.
• Feel: When you gently scoop up a bit of dough, it feels airy and stretchy, not dense and tight.
• Jiggle test: Give the bowl a gentle shake. A well-fermented dough will have a soft, bouncy wobble instead of feeling stiff and solid.

If the dough is super puffy, very bubbly, and tears easily when you handle it, it might be a bit over-proofed. Don't worry—you can still usually shape and bake it; just expect a slightly flatter loaf. Make a note and shorten bulk next time.

6. What are stretch and folds and why do I do them?

Stretch and folds are a gentle way to build gluten strength in your dough without traditional kneading. They're especially helpful for wetter sourdoughs.

Here's the basic idea:

• During bulk fermentation, every 30–60 minutes you grab one side of the dough, stretch it up, and fold it over itself.
• Turn the bowl and repeat 3–4 times so you've stretched and folded all around the dough.
• Cover it back up and let it rest until the next round.

Why bother?

• It strengthens the gluten network, helping your loaf rise higher.
• It evens out the temperature and gases in the dough.
• It lets you handle high-hydration doughs without adding more flour.

Think of it as gently training your dough instead of putting it through a boot camp.

7. Why is my bread so dense?

Dense sourdough happens to everyone. It's not a sign you're a bad baker; it's a sign your dough needed something different. Common reasons include:

• Under-fermentation: The dough didn't get enough time to rise during bulk or final proof. It may have looked a little puffed, but not enough gas developed inside.
• Starter not strong enough: If your starter isn't consistently doubling and bubbly, it won't have the power to lift your dough.
• Too much flour added during shaping: Excess flour can create a dry, tight crumb.
• Very aggressive handling: If you deflate all the gas while shaping, the oven has to start from almost zero.
• Oven not hot enough or no steam: A strong initial blast of heat and steam helps the loaf spring up before the crust sets.

When you get a dense loaf, use it as a little detective mission. Check your starter health, fermentation times, and dough temperature. And remember: dense bread still makes great toast, croutons, or bread pudding.

8. Why is my bread too sour or not sour enough?

That “sourdough” tang is all about fermentation time, temperature, and feeding habits. You get to dial it in like a flavor knob.

If your bread is too sour:

• Use your starter younger (a bit before it reaches its absolute peak).
• Shorten fermentation times slightly, especially in the fridge.
• Feed your starter more frequently so it doesn't get overly acidic between feeds.

If your bread isn't sour enough:

• Let your dough ferment longer, especially during cold proof in the fridge.
• Try using a higher ratio of ripe starter in your dough.
• Experiment with a stiffer starter (less water) or more whole grain flour, which can encourage more acidity.

There's no “right” level of sourness—it's all about what you like. Keep notes so you can repeat the loaves you love.

9. Do I have to score my bread?

Scoring (making cuts on the dough before baking) isn't just for pretty designs—it's how you give your loaf a place to expand in the oven.

If you don't score, the bread will still try to expand, but it might burst randomly along the sides or bottom. Sometimes that looks rustic and charming, and sometimes it looks like an exploded football. Your call!

At minimum, I recommend making one confident, deep slash (about 1 cm / 1/2 inch deep) along the top of the loaf. Once you're comfortable, you can play with decorative patterns. But you definitely don't need fancy scoring to make delicious bread.

10. How long should I let my bread cool before cutting?

This is the hardest part, I know. Your bread smells done long before it's ready to slice. But the inside is still setting up as it cools; cutting too early can make the crumb gummy and squished.

As a general rule:

• Wait at least 1 hour before slicing a small loaf.
• For larger, high-hydration loaves, 2 hours is even better.

If you're aiming for the best texture, let it cool completely. If you absolutely must cut sooner, know that the crumb may be a little gummy—still tasty, just not fully set.

11. How do I store sourdough bread?

Sourdough keeps better than many yeasted breads, but it still needs a little care.

For short-term storage (1–3 days):

• Let the loaf cool completely.
• Store it cut-side down on a cutting board and cover it with a clean kitchen towel, or keep it in a paper bag.
• You can also use a bread box or linen bag to balance moisture and airflow.

Avoid plastic bags or airtight containers at room temperature for whole loaves—they tend to soften the crust and encourage mold.

For longer storage (more than 3 days), freezing is your best friend (more on that next).

12. Can I freeze sourdough?

Yes, and you should! Sourdough freezes beautifully, and it's a great way to make the most of your baking.

To freeze a whole loaf:

• Let it cool completely.
• Wrap it tightly in foil or beeswax wrap, then place it in a freezer bag.
• When you're ready to eat it, let it thaw at room temperature while still wrapped, then refresh in a 300°F (150°C) oven for 10–15 minutes.

To freeze slices:

• Slice the cooled loaf.
• Arrange slices in a single layer on a tray and freeze briefly, then transfer to a freezer bag.
• Toast slices straight from frozen for almost-instant fresh bread.

Your future self will thank you when you remember there's sourdough waiting in the freezer on a busy morning.

If you're still feeling unsure about any of these steps, you're not alone. Sourdough is one big, delicious experiment, and even experienced bakers have off days.
