190-hour Baguettes Tradition & Sourdough Baguettes

190-hour Baguettes Tradition & Sourdough Baguettes

RoundhayBaker's picture


I’ve been experimenting with ultra-long (seven day) bulk fermentation of both traditional and sourdough baguette batches. Why? Because the longer a dough ferments, the more tasty organic aromatics are packed into the dough by the yeast and lactobacilli. Lactobailli in a non-sourdough baguette tradition? Oh yes, that’s because the dough ferments for so long that they get a chance to colonise it. The proof is in the tasting.

This bread is not for the inexperienced. On the one hand, the dough ingredients are simple. On the other, I wouldn’t recommend attempting this until you have mastered the tricky art of making ordinary baguettes and can regularly produce well-shaped loaves with a good grigne . That’s because, after seven days, the dough is very fragile and needs to be shaped both gently and swiftly, and then scored with great care and good technique. As you can see from the photos below, some methods work better than others. However, it is the taste you're after not a competition standard loaf.

Also, during mixing, you need to be able to judge by eye and feel if your dough is hydrated correctly for baguettes. Over- or under-hydration will create problems if you aim for the full seven days of fermentation. Being able to decide when the gluten is well-developed in the dough is also important. You need to know when to stop the stretch-and-fold cycle.

You do not, of course, have to cold retard the dough for the full duration. Baking after two, three days etc. is fine. They will still be really tasty.

I've posted a baguettes tradition recipe adapted just a little from KAF's baguette recipe. I think it's one of the best for a home baker. It's from Jeffrey Hamelman so it has to be good. I've added some semolina to the poolish because of the great durum taste and texture it gives.

For those who already have a favourite sourdough baguette recipe that should work just fine. I've tried this with a couple of my favourites and they turned out well. A rye or spelt starter adds a nice bit of texture and flavour.

113 g
water (Poolish)
1⁄2 g
Instant Dry Yeast (Poolish - a pinch (1/8 tsp))
120 g
Strong Bread Flour (≧12.4%) (Poolish)
25 g
Semolina* (Poolish)
258 g
250 g
Water** (225-290g. Precise amount varies with humidity etc.)
416 g
Strong Bread Flour (≧12.4%) (I use 13.2%)
4 g
Instant Dry or Active Dry Yeast** (3g for IDY, 5g for ADY. 1 tsp of either would be fine)
12 g
salt (10-14g would be fine)
2 1⁄2 g
Barley Malt Extract (1/2 tsp. Optional, for extra flavour)


* Medium-fine semolina is best

** Water temperature is critical, you must factor this using the Desired Dough Temperature calculation where the final dough temperature is 23-26℃ (74-79F) with the lower end of the range being preferable.

***3-5g. Lower figure for Instant Dry, the higher for Active Dry, but somewhere in the middle will do. This is not going to be a quick fermentation!

  1. Make the poolish: Mix flour, semolina, water (at 25℃ / 77F), and a pinch of yeast.
  2. Let it rest for about 14 hours/overnight at room temperature. 
  3. Make the dough: Establish Desired Dough Temnperature (23-26℃ / 74-79F) and calculate required water temperature.
  4. Autolyse the flour and water in a bowl for 20-30 minutes.
  5. Add the poolish and mix. Add the yeast, salt, and optional barley malt extract. 
  6. Mix until the dough becomes cohesive.
  7. Knead, stopping when the dough is still a bit gnarly (about 5 minutes on speed 2 of a stand mixer).
  8. Bulk Fermentation with Stretch-and-Fold (S+F): Place the dough in a covered container, and let it rise for 50 minutes
  9. Deflate it the dough gently, then S+F for at least one complete turn (i.e four quarter turns). Stop when you feel the dough beginning to stiffen and resist.
  10. Let it ferment for another 50 minutes
  11. Repeat the S+F. By now the dough should firmly resist your pull. Be careful not to rip it.
  12. Short Cold Retard: Then place immediately in a refrigerator at 8-12℃ for 12-14 hours.
  13. Scale & Pre-shape: Weigh and divide the dough evenly by three.
  14. Shape each piece gently into a rough boule. Do not over-work the dough.
  15. Flour heavily then return the boules to the bowl.
  16. Long Cold Retard: Return bowl to the refrigerator (8-12℃ / 46-53F) for up to 7 days.
  17. Shape & Prove: Flour your couche, making sure to rub the flour in.
  18. Remove and gently separate the boules. The longer the dough ferments, the more fragile it becomes so be very careful.
  19. De-gas each piece of dough. Gently, of course.
  20. Fold and seal (three times is usually enough). Work quickly with very light hands.
  21. Roll out to approx. 30cm (12 inches) - avoid crushing at all costs - and lift carefully onto the couch. Cover and prove for 20-25 minutes (start checking after 15 min).
  22. The Twist (optional): As you can see from the photos below, I used Éric Kayser’s Twist technique to shape some baguettes with some success. This involves a second shaping stage where, after 15-20 min, you dust the baguette heavily with flour, then press down lengthways with a rolling to create a central indent. You then twist the dough, whilst holding one end firm (and gentle, of course) - usually for three complete turns - before returning to the couche to prove for another 15-20 minutes.
  23. Meanwhile, pre-heat oven to 240/220℃ (fan) - 460/430F.
  24. Score & Bake: When ready, roll the baguettes onto a peel and transfer to a baking tray/sheet.
  25. I used both the traditional scoring method with a lame but also scissors to create epis de blé. Twists need no scoring. The lame was the least successful because the dough is so fragile. Cuts either healed or blew apart. With the epis, you usually get a pleasing shape no matter what the dough does.
  26. Place the tray/sheet in the oven directly onto your baking sone, and add steam, (FAN ONLY:  switch off fan for 1 minute) then turn heat down to 230/210℃ / 440/410F.
  27. Bake for 24-30 minutes
  28. Release the steam after 12 minutes. Rotate the loaves if necessary. 
  29. Leave to cool for at least 30 minutes.



Only occasionally did I get a perfect looking baguette tradition: maybe one-in-three. The gentler you are with the shaping the better they will be, but with the dough being so delicate, some luck is still required at this hydration level. As you can see above, epis de blé look good even if the cuts heal. Because you can't work too long on rolling out the dough evenly, the twists and baguettes are harder to keep to a uniform width.

Internally, you do get a good random cell structure but fewer of glossy cell walls than you'd find in a shorter fermentation baguette. However, in my experience, the taste is exceptional.

Anyhow, it's been good fun pushing these doughs as far as possible. If you have a go, I'd love to hear your feedback.

This is a really interesting post.. I wouldn't have thought that dough could survive a seven day bulk ferment! But what does it taste like that is so different from your other well made baguettes? Define exceptional.. hungry fans want to know..

RoundhayBaker least I find it so; there are so many subtle back notes that combine to make tasty bread. However, I these loaves are much more flavourful than an ordinary baguette. And my customers agree. It's not just me. If a poolish-based baguette made without old dough can become mouthwateringly tangy that's exceptional. Why not try it yourself?
