France Apprenticeship

Hi, I’m planning to have a summer (August) experience in South France - Provence, Savoie - that is centered around bread and bread making. I already possess the basics of sourdough bread, so ideally a one month long apprenticeship would be better than a short class where I suppose that given the short duration only the basics would be covered (plus some extras like pastry which I’m not interested to).

Do you have any tip to share? Thank you for your time.
