How to Make Sourdough Starter at Home: A Complete Guide for Beginners

Making sourdough starter at home is an ancient and fascinating art that allows you to produce bread and other baked goods with superior texture, flavor, and nutritional quality. In this guide, we will walk you step-by-step through creating your sourdough starter using an easy recipe from master baker Massimo Lolli. We will also explore the benefits of sourdough and answer all your frequently asked questions on the topic.

What is Sourdough Starter?

Sourdough, also known as sourdough starter, is a mixture of flour and water that naturally ferments due to the presence of yeast and lactic acid bacteria. This spontaneous fermentation gives sourdough its unique characteristics, making it a fundamental ingredient in traditional baking. Unlike commercial yeast, which consists of a single type of yeast (Saccharomyces cerevisiae), sourdough contains a variety of microorganisms that contribute to developing complex flavors and a more digestible bread structure.

Origins of Sourdough Starter

The origins of sourdough are lost in history. According to legend, it dates back to around 2000 B.C. in ancient Egypt. It is said that a piece of unleavened bread dough, forgotten in the sun, began to ferment spontaneously, turning into a puffy and slightly acidic mixture. When baked, this dough produced a softer, more fragrant bread, marking the birth of leavened bread.

Benefits of Sourdough Starter

Sourdough offers numerous benefits over commercial yeasts:

Better Digestibility: Thanks to long fermentation, bread made with sourdough is easier to digest and may be better tolerated by those with gluten sensitivity.
Nutrient Absorption: Sourdough fermentation improves the absorption of essential minerals such as calcium, magnesium, iron, and zinc.
Reduction of Phytic Acid: Sourdough reduces levels of phytic acid, a compound that can inhibit nutrient absorption.
Natural Preservation: Sourdough acts as a natural preservative, improving the shelf life of baked goods.
Glycemic Index Control: Sourdough bread has a lower glycemic index than traditional bread, making it suitable for diabetics.
Feeling of Fullness: Due to its composition, sourdough contributes to a greater sense of fullness, helping control appetite.

How to Prepare Sourdough at Home

Preparing sourdough starter requires time and patience, but with this detailed guide, even beginners can achieve great results.

Characteristics of the Flours Used

The flours you use to prepare your sourdough starter play a crucial role in the fermentation process and the final quality of the starter. Our flours, made from Italian wheat, are additive-free and contain live wheat germ, an element that can positively influence the health and vitality of the sourdough starter.

Benefits of Our Flours for Sourdough Starter:

Natural Purity: The absence of additives ensures that the flour retains all its natural properties, promoting healthier and more natural fermentation.
Live Wheat Germ: The live wheat germ present in our flours is a rich source of essential nutrients, which not only improve the nutritional profile of the sourdough starter but also enhance its fermentative capacity. This contributes to a more vigorous and active starter capable of producing bread with superior structure and flavor.
High-Quality Italian Wheat: By using high-quality Italian wheat, product traceability and purity are guaranteed, essential for those seeking authenticity and health in their baked goods.

Necessary Ingredients

To start, you will need a few simple ingredients:

200 grams of soft wheat flour type “0” with a W of about 320, ideal for the initial phase of creating the sourdough starter.
100 grams of lukewarm water.
2 jars of organic low-fat yogurt (alternatively, you can use organic honey, organic grape juice, or barley malt), which will act as a starter to activate fermentation.
For subsequent refreshments: a soft wheat flour type “0” with a W of about 410, to maintain the strength and vitality of the sourdough starter.

Procedure

Step 1: Preparation of the Initial Dough

Place 250 grams of soft wheat flour type “0” with wheat germ in a bowl. Add the two jars of organic low-fat yogurt (or honey, grape juice, or barley malt) and the lukewarm water. Knead well with your hands until you obtain a soft but not sticky dough. Transfer the dough to a floured board and work it until you get a smooth ball. Place the dough in a glass bowl, make a cross on the surface, and cover with plastic wrap, making a few holes with a toothpick. Let it rest at room temperature for 48 hours.

Step 2: First Refreshment

After 48 hours, take 200 grams of the fermented dough and add 200 grams of flour and 100 grams of lukewarm water. Knead until you get a new dough. This process, called “refreshment,” nourishes the yeasts present in the dough. Cover and let rest for another 48 hours.

Step 3: Subsequent Refreshments

Continue to refresh the sourdough every 48 hours for at least one to two weeks. The sourdough starter will be ready when it can double its volume in about 4 hours. Once ready, store the starter in the refrigerator in a glass jar and refresh it weekly.

In Conclusion

Making sourdough at home is a process that requires patience and dedication, but the final result is well worth the effort. Sourdough not only improves the flavor and texture of your baked goods but also offers numerous health benefits. By following this detailed guide, you can create your sourdough starter and discover the ancient art of traditional baking. Happy baking!
