About dough hydration part2

First of all, thank you for every message, feedback and like I get every day. It makes me wanting to continue write and share my ideas and why not? secret toughts :D
As I have been enquired to write a follow up of the dough hydration piece; Going more in-depth with hydration effects on the different bread types (Italian breads in particular), here we go!
I decided to write this right now, with a cup of fresh ground coffe in the hand while watching my dogs sleeping on the floor :)
As I wrote in the previous post, here in Italy we have different main dough hydration levels which tend to produce different final products:



Bread type:                                                               Average hydration:

Ciabatta                                                                    <75% - 90%

Pane comune (di grano tenero)                                <60% - 75%

Pane di pasta dura (Ferrarese, Biove)                      <45% - 50%




We saw that most of these products can be done by apply the right tech, with different hydration levels and still obtain a similar level of lightness in the crumb.
Let' s see now the point by another perspective. How water percentage affects a dough for every tech and recipe listed above?

A close up of a Ciabatta crumb 80% hydration

Ciabatta:

Typically starting with an hydration of 75% (back in the years when in Italy were not available strong flours). The minimal manipulation of the dough, and the fermentation level reached in bulk phase, give you that light open crumb which is best appreciated while slicing this bread on the hotizontal plan (so the fillings of the sandwich will fall into the air pockets .. yumm).
When hydration is raised up in this bread, you get more fluffiness and a more polished texture as well as bigger air pockets. However by raising too much the water percentage (let s say above 120% using strong flour) the air pocket size tend to decrease but augment in number, giving you the micro-pockets structure.
On the other hand, when you lower down hydration levels, you will have a more regular air pockets distribution as well as a raw texture.

Pane comune with 68% hydration

Pane comune:

Typically in between 60% and 75% hydration range. It is made with mid-strenght to weak flours (protein level range in between 11% to 9%).
It has a more compact crumb structure compared to ciabatta due to the shaping phase that compress a bit the pockets. The more you high the water percentage, (using a same strenght flour) the more you get big holes but irregular due to a stronger fermentation as well as a difficoult shaping. Texture will be softer as well, and polished like in Ciabatta.
The lower you go with water percentage, the more you get a regular crumb with little air pockets. The texture, in this case, will get raw and less chewy.

Pasta dura, not laminated

Pasta dura:

Typically in the 45% - 50% range (in few cases it reaches 55%) of hydration. It is made with mid-low strenght flours (10%) but can be done also with strong flours (<11%). Is it characterized by a close structure with occasional pockets (many bakers consider air pockets a defect so they push out all the gases from fermentation by laminating the dough several times). There is not much room to change hydration percentage here due to the unique crumb structure that need to have this bread.

About dough hydration

Hello people! today I want to speak about hydration in bread dough.
I think it's time to demystify a bit the importance of water's percentage influence in a dough.
Let' s say that the second most important ingredient in bread making process have a great influence on the final product as well as on the entire production chain.
Right; But, and there is a big but here, it's not the most important element nor the only one which concours in having a light open crumb that most people are looking for in sourdough baking.
I will not discuss here if it' s right or wrong, just let' s assume that an open crumb it is what one aim for.
Water, H2o. Is the life itself. Is the thing that we all need to survive, to stay healthy, to stay clean.
As the ferments are living beings, they also need water to survive. And they need good water to stay healthy and clean.
So, admitting we have a good balanced pure water, let's get back to the amount of it we put in a dough and what it will influence.
I take as example breads that are normally made in Italy.
I can say we have different main doughs with different hydration levels:

Doughs:                                                                           Hydration %


Pizza&Focaccia (tray)                                                    <80% - 100%
Ciabatta                                                                           <75 - 90%
Pane comune (Filone, pagnotte)                                     <60 - 75%
Pasta dura (Ferrarese, Biove ...)                                      <45 - 50%

The goal of each dough is to have the right consistency for the process they need to pass throught.
From minimal manipulation of Pizza and Ciabatta (they are very similar doughs even if in pizza dough is more common to use olive oil than in ciabatta) to the more intensive of pasta dura breads.
However, we can do Ciabatta with 58% hydration, in example, and the structure of bread will be similar to a 78% one because of the same process.
This is proof that hydration is not so important in having open crumb.
Be aware that meanwhile the air pockets can be obtained at lower hydration levels, the texture of the crumb will be different without any doubt.
As while I' m writing this article I am eating a piece of high hydration bread, I can say that texture is softer and smoother than low hydration ones. Flavour also is different because in high hydration breads fermentation is producing more byproducts and faster. Meanwhile in low ones you can feel much more the grain itself.
To me the goal is to have a good texture, with good flavour and lightness. I do appreciate every hydration bread levels as long as they are made with the right fermentation and tech which bring to an open structured crumb.
