Study Notes

Autolyse Technique

Developed by Professor Raymond Calvel, a leading expert on French bread production
Autolyse means "self-smoothing rest" period
Beneficial for French bread production and naturally leavened sourdough breads (except rye-based)

Process of Autolyse

Mix final dough flour and water at slow speed
Do not include salt, yeast, or pre-ferments (except liquid levain or poolish)
Cover and rest for 20 minutes to an hour
Flour hydrates and gluten bonds develop during rest period
Add remaining dough ingredients and mix on second speed
Mixing time reduced by 40% or more

Benefits of Autolyse

Reduces overall mixing time
Minimizes oxidation of carotenoids
Results in more aromatic loaves with a creamier, more open crumb and more pronounced cuts
Can improve loaf volume, especially with high-protein flours or sourdough breads
Allows easier dough expansion in the oven
Favors better water absorption in whole-wheat flour doughs

Importance of Autolyse Rest Period

Gluten bonds develop during rest period
Flour enzyme protease breaks down protein bonds, improving loaf volume
Bran absorbs more dough water, reducing cutting action on gluten strands

Exceptions and Considerations

Salt, yeast, and pre-ferments are not added to autolyse to prevent tightening of gluten network or incipient acidity
Liquid levain or poolish can be used as an exception
High percentage of overall dough water in pre-ferment ensures sufficient hydration of flour
