FAQs

How do you know if sourdough is fermented enough? ›

Under fermented bread will not spring up in the oven. It's dense, gummy and often pale (depending on the degree of under fermentation). Dough that has not been bulk fermented long enough will also be difficult to shape, sticky and will often spread once tipped out the banneton. Good sourdough takes time!

PROBLEM - You may have baked a loaf of sourdough which appears to have large tunnels of air or just one big hole surrounded by a tighter or dense crumb. CAUSE - This is typically caused by under fermenting your dough, but can also happen through using too much flour when you shape your bread.

If your sourdough starter won't rise anymore, reset it by putting 25 grams of starter in a jar and feed it 50 grams of flour and 50 grams of water. With this ratio, your starter should double in size in about 12-24 hours. If your starter has never risen before, follow a proven guide to create an active starter.

Uneven Crumb

If your sourdough has a tight crumb that has some random larger holes or perhaps it has lots of big holes but they just don't seem right, chances are you have an under fermented loaf of sourdough that needed more time in bulk fermentation.

Dough that is over-fermented will start to spread once scored and look bubbly/weak. You'll notice it falling in a bit or a lot. Notice how the whole loaf is collapsing. If you notice your dough is over-fermented be sure to score very shallow and use a minimum of scoring slashes.

You bake your sourdough too soon

Whether you've just adopted a sourdough starter of your own, or have made a sourdough starter from scratch, you'll need to wait a few days to a week until your starter is ready to bake. Yes, your starter might look bubbly, but that doesn't make it strong enough to use.

Underproofed dough is dense and has not increased in volume. This will result in a dense bread with a very tight crumb (holes are very close together) that doesn't have the pillowy texture when you take a bite. The flavor will also be underdeveloped.

Little did I know that baguettes are considered the most difficult bread to bake, and “the art of artisan breads.” For the first six months, I baked three baguettes every day, generally wondering why anyone would go to all of the trouble.

Does it matter if my starter is thick or thin, you ask? Nope! Thick and thin starters are both full of wild yeasts and bacteria which is what your bread is begging for. The viscosity of your starter is really just a personal preference because thick and thin starters will both make bread.

Should sourdough starter have big or small bubbles? ›

As long as your starter is doubling (or even tripling) in a timely manner after being fed, the size of the bubbles don't really matter too much. What you're looking for is activity and fermentation. Bubbles of any kind are an indication that this is happening inside your jar.

Do I have to discard my sourdough starter? It would be best if you discarded some portion of your starter each time you feed it unless you want to continue to let it grow. Eventually, you need to discard the used “food” (flour and water) that's been used to sustain your starter during the last fermentation period.

If your starter gets completely covered on top with bubbles but does not rise, it is healthy but may just be a wet mix. Try reducing the water in your next feeding and see if you have different results. Also, the type of flour you are using can impede the rise of your starter.

If you're like me and have neglected your starter for a little too long — perhaps you've been out of town or simply forgot it in the back of the fridge — you can use a little whole grain flour (such as pumpernickel or whole wheat flour) to feed your starter and give it a boost.

Flour with more protein and nutrients make sourdough starter more active, so consider feeding your starter with bread flour, whole wheat flour, rye flour (or a combination of these) to increase fermentation activity and rise. Thicken the starter (lower hydration ratio).

Typically, bulk fermentation will take between 6 to 8 hours, but could be longer or shorter by manipulating starter amount and temperature. Ideally, you don't want to allow sourdough bread to cold ferment for longer than 72 hours.

If you over-ferment the dough you run the risk of the gluten structure degrading and the loaf turning into a puddle of goo before your eyes, never to be retrieved and destined for the bin.

However, the longer the dough ferments (and especially at warm temperatures), the lactic acid bacteria stimulates something called the “protease enzyme.” The protease enzyme eats gluten and starts to deteriorate your loaf.

Overproofed sourdough is preventable but also salvageable. Reshape the dough, bake it as a pizza or flatbread dough, or bake it and turn it into breadcrumbs for granola.
