Success in sourdough baking starts with understanding why these problems occur.

A detailed guide explores the most common sourdough problems bakers face today. Bakers will discover how to spot signs of under-fermentation and over-fermentation that affect their bread. They’ll become skilled at proper shaping techniques and learn to achieve the perfect crust through steam and temperature control. Clear solutions in each section help create beautiful, well-fermented loaves with even crumb structure and excellent oven spring.

Understanding Common Sourdough Issues

Making perfect sourdough bread depends on mastering the delicate balance of fermentation, temperature, and technique. Bakers face several common problems with their final loaf if these elements fall out of balance.

Gummy or dense crumb

A gummy or dense crumb creates one of the most frustrating problems in sourdough baking. The bread demonstrates a heavy texture with a moist, dense interior. Several factors cause this problem:

• An immature or inactive starter
• Insufficient bulk fermentation time
• Dough temperature that’s too low
• Under-baking

Bakers can solve the problems of gummy crumb by using a starter that’s at least 14 days old and keeping a steady temperature of 75°F (24°C). Extending bulk fermentation time helps the yeast and bacteria develop proper dough structure.

Dough spreading when removed from banneton

The dough can lose its shape right after coming out of the banneton. This creates flat and wide loaves instead of tall, rounded ones. Several factors cause this unwanted spreading.

Incorrect shaping techniques are the main reason behind this problem, though fermentation can affect it too. A properly fermented dough feels alive and warm without becoming slimy. Proper shaping creates surface tension that helps your dough hold its shape during its vital journey to the baking vessel.

Uneven crumb structure

Your bread’s uneven crumb structure shows up as large holes surrounded by dense areas, which points to fermentation problems. You might notice these signs:

• Big random holes near the top
• Dense areas scattered in the crumb
• Compact crumb with some large bubbles

Better fermentation management will fix this problem. A properly fermented dough creates an even, open, and lacy crumb pattern. Temperature control is significant – your dough needs to stay around 75°F to ferment evenly throughout. Adequate bulk fermentation lets gasses spread uniformly and stops irregular holes from forming.

Bakers should build a strong gluten network through mixing and folding to get the best results. This network gives the dough enough strength to trap gasses and create an even crumb structure. Look for clear fermentation signs before shaping – a slight dome and tiny bubbles should appear on the dough’s surface.

Troubleshooting Fermentation Problems

Proper fermentation determines the success of sourdough baking and remains the most challenging skill to develop. The ideal range of 76-78°F (24-26°C) plays a significant part in achieving optimal fermentation activity.

Signs of under-fermentation

Experienced bakers recognize under-fermented dough by several distinct characteristics. These key indicators include:

• Dough feels dense and lifeless
• Minimal or no increase in volume
• Lack of surface bubbles
• Dense, gummy texture when baked
• Uneven crumb with random large holes
• Pale crust that refuses to brown

Weak starters or temperatures below 70°F (21°C) often lead to under-fermentation. The dough will lack the characteristic sourdough aroma and feels heavy to touch.

Signs of over-fermentation

Over-fermented dough creates distinct challenges. The dough shows several problematic characteristics at the time fermentation exceeds its limit:

• Excessive stickiness and poor shape retention
• Stringy, web-like appearance under stretching
• Strong, unpleasant sour smell
• Dough tears with ease during shaping
• Reduced oven spring
• Compressed crumb structure

Bacterial activity degrades the gluten structure in over-fermented dough through proteolysis. This degradation produces weak dough that bakers struggle to shape properly. This commonly occurs in warm environments above 80°F (27°C) or through extended bulk fermentation periods.

Adjusting bulk fermentation time

Successful bulk fermentation depends on environmental conditions and how your dough behaves. Here’s what you need to know about proper adjustment:

1. Keep track of your dough temperature as it ferments
2. Your timing should shift with room temperature:
   • Above 78°F: Cut down fermentation time
   • Below 75°F: Let it ferment longer
3. Look for visual signs that show proper fermentation
4. You might need less starter in warm weather
5. Mix with cold water if it’s hot outside

Bakers should stay away from bulk fermentation in the refrigerator. Temperatures below 40°F (4°C) slow down yeast activity by a lot. A proper bulk ferment requires temperatures above freezing. The process works best with steady warmth throughout.

At the time you work in different conditions, your dough in warmer areas may need more frequent refreshing and less starter. Cold environments often call for more starter or extra fermentation time. The key is to let the dough guide the timing rather than strictly adhering to recipe timeframes.

Mastering Shaping and Scoring Techniques

Becoming skilled at shaping and scoring turns an ordinary sourdough loaf into professional-quality bread. These significant techniques shape the bread’s final texture and determine its rise and appearance.

Proper shaping for better structure

The right structure comes from proper shaping, and everything in achieving an airy, well-risen loaf depends on it. Shaping creates surface tension that helps the dough trap gas bubbles effectively. This leads to better oven spring and creates a lighter crumb structure. Bakers need gentle yet firm hands at the time they shape the dough. They must take care not to deflate those carefully developed air pockets.

Bakers should follow these steps to get the best results:

1. Lightly dust the work surface
2. Pre-shape the dough and let it rest for 15-20 minutes
3. Create tension through gentle pulling and folding
4. Avoid excessive flour during final shaping
5. Maintain consistent pressure when rounding

Working with high-hydration doughs needs extra attention to prevent sticking. A bench knife is a great way to get control over sticky dough without compromising the dough’s structure.

Scoring tips for optimal oven spring

The right scoring technique is vital to control how your bread expands in the oven. You need swift, confident movements and proper tools to master this skill. Cold dough scores more cleanly, so refrigerated proofing helps you make precise cuts.

Here’s everything in scoring you need to know:

• Sharp bread lame works better than a regular knife
• Your blade should sit at a 30-40 degree angle
• Cut about 1/4 to 1/2 inch deep
• Quick, confident cuts give better results than hesitant ones
• The dough needs scoring right before it goes into the oven

The correct blade angle is a vital part of creating that coveted “ear” on your loaves. A 45-degree angle creates a lip that lifts during baking and produces that distinctive ear – the hallmark of a perfectly scored loaf.

Fixing splitting issues

Bread splits in unexpected places during baking, which often points to problems with either fermentation or scoring technique. Under-fermentation leads to random splitting because the dough keeps too much energy and bursts through weak points during baking.

Bakers need these elements right to avoid unwanted splitting:

1. Complete fermentation before shaping
2. Even tension distribution during shaping
3. Deep enough scoring to direct expansion
4. Steady steam levels during original baking
5. Right oven temperature throughout baking

Scoring and splitting have a crucial connection, especially when you have decorative patterns. Bakers should always include one deep “utility” score among their decorative cuts to guide the bread’s expansion during baking.

The bread’s success depends heavily on temperature control. Cold dough around 40°F (4°C) gives better control during scoring and helps maintain shape before going into the oven. Swift transfer from refrigerator to oven helps the dough keep its structure and prevents warming.

Bakers should practice scoring on cold dough with quick, decisive cuts to achieve great results. The blade needs to glide through the dough smoothly without dragging and create clean lines that open beautifully during baking. New blades will give continued precision since dull ones can tear the dough’s surface instead of cutting it cleanly.

Perfecting the Bake

Becoming skilled at the baking process represents the final stage of creating perfect sourdough bread. A well-shaped loaf changes into a masterpiece when bakers properly manage temperature control, steam management, and cooling techniques. The result is bread with a crackling crust and perfect crumb structure.

Achieving proper internal temperature

Your sourdough bread’s internal temperature will give a perfect bake every time. The ideal internal temperature should reach 205-210°F (96-98°C) when done. But temperature alone won’t tell the whole story – the bread needs time to develop its crust color and structure.

These baking steps will lead to great results:

1. Heat your oven to 500°F (260°C) with the baking vessel inside
2. Lower temperature to 475°F (246°C) as you load the bread
3. Keep the bread covered while it bakes for 20-25 minutes
4. Take off the cover and bake at 465°F (240°C) for 25-30 minutes
5. Test the loaf’s center temperature
6. Take multiple readings to check even heat distribution

The bread’s final internal temperature acts as a backup check rather than the only sign of doneness. You should also think over the crust color, listen for a hollow sound when tapped, and look at the overall appearance.

Creating steam for better crust

Steam plays a significant role during the first phase of baking and keeps the dough surface pliable while the loaf expands. The first 20 minutes of baking require consistent steam to achieve optimal oven spring and crust development.

A Dutch oven’s natural steam environment comes from the bread’s own moisture. Bakers can use several methods to create steam when baking in an open oven:

• Preheated cast iron pan with lava rocks or chain
• Rectangular pan with saturated towels
• Spray bottle for additional moisture
• Ice cubes in a preheated pan

The bread’s surface needs just a thin film of moisture rather than a saturated oven environment. Too much steam can result in pale crust and reduced oven spring. The proper crust development requires removal of steam sources after the steaming period ends.

Cooling techniques for best results

Bread completes its final change through a process called retrogradation during cooling. This significant phase lets moisture spread properly and develops the crust. Proper cooling requires patience – cutting hot bread ruins the texture and creates a gummy crumb.

The bread’s size and ingredients determine cooling time:

• Small rolls: 30 minutes
• Standard white loaf (1 lb): 2 hours
• Large whole-grain loaf (1.5 lb): 4 hours
• Rye-based loaves: 4-6 hours

Fresh bread needs to rest on a wire cooling rack to get the best results. This lets air move around the loaf completely. The cooling process finishes the starch’s transformation and makes the bread easier to slice with better texture. Room temperature should be managed to keep around 70-75°F (21-24°C) while cooling.

Never cover hot bread or put it in plastic bags – these common mistakes trap moisture and make the crust soft. Let the bread cool to body temperature before slicing. Standard loaves usually need 1-2 hours. Proper cooling will give even moisture distribution throughout the crumb and develops better texture and flavor.

The bread goes through several chemical changes as starch molecules arrange and water moves toward the crust during cooling. This process makes the bread’s structure stronger and creates its final texture. Rushing the cooling process can result in gummy crumb with uneven moisture and poor crust quality.

Conclusion

Becoming skilled at sourdough bread depends on understanding how fermentation, temperature control, and technique precision work together.

FAQs

What is the most significant error you can make with your sourdough starter?
A common mistake is not maintaining the correct temperature for your sourdough starter. If the temperature is too low, around 70°F (21°C), the fermentation activity slows down, causing the starter to rise slowly and show delayed signs of fermentation. To fix this, ensure your starter is kept warm.

What are typical mistakes when baking sourdough bread?
A frequent issue is the dough being too cold, which prevents the starter from effectively fermenting all the flour, resulting in a dense bread with fewer air pockets. Ideally, the starter should be kept at about 75 degrees to be most active.

Why does my sourdough bread turn out doughy in the center?
This problem often arises from underbaking the bread. Ensure you bake it for a sufficient amount of time. Additionally, check if your baking pan is too small, as a cramped space can restrict the bread’s growth and prevent it from baking thoroughly.

What could be causing issues with my sourdough bread?
If your sourdough loaf is dense, has uneven air holes, and a gummy texture, it’s likely due to insufficient active wild yeast in your starter. This issue can occur even if your starter appears bubbly and active.
