The "W" of a flour is a classification indicating the strength of the gluten present in the flour. Gluten is a protein found in wheat and other cereals, and it is responsible for the flour's ability to form elastic networks during the kneading process.
The "W" value measures the strength of gluten and the flour's ability to retain gas produced during fermentation, thus determining the final consistency of the bakery product. The higher the "W" value, the stronger the flour and the greater the amount of gluten it can develop.
Flours with a high "W" value are often used for bakery products such as bread, where a stronger structure is needed to support rising. Flours with a lower "W" value are suitable for lighter bakery products, such as pastries and doughs.
In summary, the "W" value is an indicator of the flour's strength and its suitability for different types of bakery products.
Applications based on the flour's "W":
-
Flours with low "W" value (W 130-180) :
- W 130-160: Suitable for desserts, cookies, cakes, and other bakery products requiring a more delicate structure.
- W 160-180: Can be used to prepare shortcrust pastry and other sweet doughs.
-
Flours with medium "W" value (W 180-250) :
- W 180-210: Excellent for bakery products such as pancakes, muffins, and some types of lighter breads.
- W 210-250: Suitable for traditional bread, pizza, and other bakery products requiring a more robust structure.
-
Flours with high "W" value (W 250 and above) :
- W 250-300: Ideal for bread doughs with a long rising phase, like traditional bread, ciabatta, or baguette.
- W above 300: Often used for special bakery products or when a strong gluten structure is needed, such as in certain types of pasta.
The choice of flour with the right "W" depends on the specific application and the desired result. For example, to get a well-risen bread, a flour with a high "W" value may be preferred, while for a light dessert, one might opt for a flour with a lower "W" value.
