Pane a Lievito Naturale con Segale Integrale

Yesterday, I was reading about Ezio Marinato. He is a famous italian baker and teacher, one of the most representative member of the italian team at the "Couple du Monde the Boulangerie - Paris" (along with Piergiorgio Giorilli) and gold medal at the "Mondial du Pain, Goût et Nutrition - Lyon 2007".

He is also a baking consultant and I already knew him because of his work with Molino Quaglia and Farina Petra.

So, I was reading about his bread/courses/work ... and I stopped on this bread: "Pane a Lievito Naturale con Segale Integrale", that is "Sourdough Bread with Whole Rye". As I am in a "focus on process" period, or "... learn the subtle art of fermentation ..." (Shiao-Ping reminds me Hamelman's statement in the post "body and mind"), I thought this bread could be really close to the basic Pain Au Levain I'm working on.

After a receipt translation to bakers % I saw again that schema! It's a while I see that schema, maybe with some little differences in the process, and when you see the same bread made with almost the same schema by a lot of professional/inspired bakers you focus on the subtle art of fermentation.

My first thought was: this is J.Hamelman Vermont Sourdough with Increased Whole Grain but:

• not increased prefermented flour: 15% vs 20%
• not liquid levain: stiff 50% hydration vs liquid 125% hydration
• more "intensive mix" vs "improved mix"

Now that I have a better knowledge of mixing techniques and requirements (thanks to Dan DiMuzio book) I understand the main timing difference in the process: 01:00 bulk + 03:00 proof @26°C vs 02:30 bulk + 02:30 proof @25°C.

Here the original receipt, I let you play with all the math!

Ingredients: 4000g bread flour (W280), 1000g whole rye flour, 1500g stiff levain, 25g malt, 50g toasted malt, 100g salt, 3500g water.

Dough temperature: 26/28 °C

Mixing: 5 minutes speed 1 + 10 minutes speed 2

Directions: autolyze the flour with 2750g water, mix 5/6 minutes in speed 1; wait 30 minutes, then add all the ingredients and the remaining water, mix 10 minutes speed 2. Bulk fermentation about 70/80 minutes at 27°C. Division (suggested piece 500g to 1000g) and preshaping with 15 minutes bench rest, then proof at 28°C for about 3 hours. Bake.

Here my attempt at the bread. I adjusted timing and ingredients according to my environment (for example I raised the final hydration from 66% to about 68%). Next try a would go for a short mix that is higher hydration (70%) longer bulk fermentation (3 hours) with 4/5 set of stretch and fold.

This bread was prepared in my mom's kitchen and baked 3 Km far in my "new working on house" where my oven is now placed. When I will finish to build my kitchen this oven will be dismissed so this is the last opportunities to show it to you.

Here the "technical specifications": very cheap electric static oven, 20 years old, crazy temperature controller, hot in the back cool in the front, no light bulb (exploded), no door handle (broken, I use a screwdriver to open the door).
