Whole Wheat Sourdough Starter

This post will walk you through the steps to creating a whole wheat sourdough starter from scratch. A simple combination of flour, water, and time will set you up to begin baking all kinds of delicious, nutritious loaves, bagels, muffins, and more – all from your very own sourdough starter.

Sourdough Starter Recap

The art of sourdough baking is nothing new. A long time before commercial yeast, bread found its rise with the help of a living culture of natural yeasts and good bacteria – sourdough starter. These living organisms are found everywhere in our environment. 

When we leave a little bit of flour and water in a warm spot for a length of time, wild yeast and good bacteria get to work consuming the sugars in the flour and water mixture, giving off small bubbles of carbon dioxide. These bubbles give rise to our recipes when we let the dough rest.

This process of fermentation makes the grains more digestible, and the nutrients become more bioavailable. 

These natural benefits have been largely replaced by the convenience of instant yeast and quicker rise times. 

While we save time, we have also been losing the nutritional benefits and delicious flavors.

But sourdough starter has been making a comeback. It is finding its way back into the kitchens of average folks, its popularity rising because of the many benefits, and maybe also because of the extreme satisfaction that comes with learning to master this lost art.

I use my starter constantly, and I’ve been caring for it for years now. It’s practically a member of our family.

Sourdough starter is a living thing, incredibly resilient, and much simpler than most think.

So where do you begin? 

Sure, you can buy a starter and get going from there.

Or you can ask a sourdough friend for some of theirs, and I’ve found they’re always excited to share.

But I think the easiest way starts in your very own kitchen. Did you know you can grow your own starter from scratch with a little whole grain flour and some water? 

I have a post for How to Make a Sourdough Starter already, and while the process is pretty much the same, that post is aimed at using all-purpose flour, and whole wheat is different.

For those wanting to use whole wheat flour in a starter, keep on reading!

Some Differences of Whole Wheat Flour

The choice of flour in a sourdough starter is completely up to you. Whole wheat is one of many great options, so let’s discuss why we might choose whole wheat.

Whole grains are made up of three main components: the bran, the endosperm, and the germ. 

Each component offers some nutrition, though some more than others. 

Bran is an excellent source of fiber, while the germ contains healthy fats and vitamins like B and E, and the endosperm contributes primarily starch.

Wheat flour is a whole grain – bran, endosperm, and germ – processed using commercial equipment or your own little grain mill at home. Each component is present, contributing to the darker color of the flour.

White flour is the result of separating the endosperm, the starchiest component, from the bran and germ. Flour composed of just the endosperm of the wheat berry results in white flour being white, as the brown outer layer of bran has been removed.

Wheat flour, therefore, boasts a much higher level of nutrition.

Also, because all parts of the wheat berry are present in unprocessed whole wheat, this type of flour uses more liquid. As such, a whole wheat sourdough recipe will typically require more hydration than others.

What’s To Love About Whole Wheat

Quicker rise

Sourdough starter made with whole wheat flour ferments much more rapidly than white flour. This is because the wild yeasts respond more vigorously to having all the parts of the wheat berry present, happily consuming the flour and water much more quickly. 

Wheat flour is great for jumpstarting your sourdough starter or for using it all the time as your primary flour.

Deeper flavor

Whole wheat flour has a very deep, complex taste, with slight but noticeably sweeter notes than all-purpose or white. Many people prefer whole wheat flour for its heartiness. 

This flavor boost comes from maintaining the bran and germ and often influences the tanginess from the fermentation. This results in a more sour flavor. 

A sourdough starter made with whole wheat flour will contribute to a more richly flavored bread, especially when used in combination with whole wheat flour in a recipe.

Hearty Texture

Whole wheat flour recipes produce a denser loaf of bread than more processed flour. This is due to a lower gluten content in whole wheat. This should be expected and isn’t really a downside. 

This density works wonderfully for a sturdy crust, chewy texture, and a well-structured loaf that accompanies any meal very well.

Used in a sourdough starter, whole wheat flour will hold fewer bubbles and tends to not rise a bread as dramatically during the bulk fermentation, unless used with a more glutenous flour like bread flour or all-purpose.

Whole Wheat Sourdough Starter Maintenance

Daily Use on the Counter

A starter kept at room temperature requires a consistent feeding of flour and water every day. 

Even though whole wheat is a higher hydration flour in recipes, you’ll still stick with equal parts flour and water for the starter.

Keep in mind that the warmer the conditions, the quicker the wild yeast and bacteria will use up the sugars and reach their peak. 

You should plan on using your starter every day on this schedule, or at least several times a week while discarding on the off days. 

I like to keep a jar of discard in the refrigerator to use specifically in discard recipes. 

I don’t actually discard my discard, but use it up in recipes made specifically for this purpose. For ideas on how to do the same, check out my post 35+ Sourdough Discard Recipes!

Refrigerated Starter

For the average person, storing your starter in the refrigerator makes a lot of sense. 

The cold slows down the fermentation process significantly, which is more accommodating for those baking weekly or every other week.

A refrigerated starter should be fed about every 7 days to keep it healthy. Depending on your starter and flour/water ratios, you may get by with feeding every other week. 

Keep the container covered tightly when refrigerated.

This method requires a bit of planning when used as an active starter, as the starter won’t be ready to go right out of the fridge. 

For best results, it will need to be placed on the counter and fed on the day before you plan to use it to rise a recipe.

For recipes that don’t require rise or use added leavening agents, such as sourdough chocolate chip cookies, Dutch baby pancakes, or discard crackers, simply bring your discard to room temperature before adding to a recipe.

When Is My Starter Ready?

The most accurate way to know if your starter is ready is by identifying visible signs of activity, such as bubbles or doubling in size. 

The age of your starter matters as well, since a very young starter may perform much more weakly than an older one.

One method I would not recommend is called the float test, and it is already a somewhat inconsistent indicator of a sourdough starter’s readiness.

It works in this way: The activity of a starter will generate carbon dioxide bubbles within, causing a sample of the starter that is placed in a glass of water to float. This would indicate an active starter. 

However, whole wheat flour has a lower gluten content than bread flour or all-purpose flour, which results in less elasticity and a weaker gluten network. 

As such, this type of starter won’t hold lots of bubbles, which will cause the starter to sink. It will likely fail this specific test, though it very well could still be active and ready to bake. 

Tips

• The temperature of your home plays a big role in the fermentation process. A warmer home will lead to a far quicker rise, whereas a cooler home slows the rise significantly.
• If you need a warm place to keep your starter, some common solutions are near a heat source like a hearth, near an operating oven or stove, on top of the refrigerator, or in a sunny window.
• Recipes made with whole wheat starter and flour work well with longer autolyse and rest periods, allowing this very thirsty whole grain flour to absorb the liquids more completely.
• A common method of measuring the growth of your starter is placing a rubber band around the jar level with your starter upon feeding. You can later check if the starter has risen past the marker, measuring the growth and timing of your starter’s peak activity. This typically happens anywhere between 4 and 12 hours after feeding.
• Starter consistency should be similar to that of pancake batter.

Tools You Will Need

Glass bowl – You will be keeping the starter in this bowl for several days, so a non-porous material like glass is best.

Wooden spoon – Metal can react with the acid in sourdough fermentations, so I generally use wooden utensils. 

Measuring cups – You can use a food scale if you want to be very accurate, but I find measuring cups to be sufficient.

Tea towel – To keep foreign particles out of the bowl.

Ingredients

Whole wheat flour – I use fresh milled flour.

Water – Filtered water is helpful to avoid chlorine and other chemicals often found in tap water.

How to Make Whole Wheat Sourdough Starter

Day 1:

Combine one cup of whole wheat flour with one cup of filtered water in your glass bowl. Stir well, scraping down the sides of the bowl. Cover your bowl with a clean tea towel and let it sit at room temperature for 24 hours.

Day 2:

Pour out and discard half of the flour and water mixture, then repeat the steps of day one. One cup of flour, one cup of water, stir thoroughly, cover, and set aside.

Day 3-5:

For days 3, 4, and 5, repeat the instructions from day 2. Discard, feed, stir, cover, and wait 24 hours.

Day 6-7:

Continue the steps from days 2-5, but begin feeding every 12 hours now, rather than every 24 hours.

Day 7:

After one week, your new starter should be showing signs of activity. With the feeding schedule and elapsed time, enough wild yeast and good bacteria should be present to attempt your first rise. Look for bubble foam on top, bubbles throughout the starter, or doubling in size.

After day 7:

Start baking with your sourdough starter. Store in the fridge if not using daily. Feed once a week in the fridge or at least every 12-24 hours at room temperature equal portions starter, water, and whole wheat flour.
