water and flour for sourdough starter

Bread is flour and water.

I’m always impressed how it is simple and genious at the same time. So I invite you to share this delight with me. But first some words about ingredient quality and so on.


Sourdough starter can be both wheat and rye.
I use a whole grain flour in most cases and this gives a good result.
My choice is whole grain flour Luomu Grahamjauho by Pirkka. Such type of flour is rich in useful elements and very tasty.


I live in Finland and we have high quality tap water.
But in my opinion this water is too soft for baking bread. So I use mineral carbonated water for both sourdough starter and baking needs.


There are several approaches to the removal of sourdough starter. It seems like the difference is due to the temperature at which the starter develops.

One time there was a three-liter jar of sourdough starter in my refrigerator. I fed it every few days and sometimes didn’t know what to do with it. Additionally the starter by itself was not as good as I would have liked. The reason of this fact you will see below.

A little bit later, there was a smaller jar in my kitchen cabinet. I fed this starter once a day and its quality also left much to be desired. By this time I’ve found out that strong and delicious sourdough starter needs ~1-1.5% of old culture for every feeding. Thereunto the part of starter is just 3-4% of the whole bread weight. In practice it means ~10 g of fresh strong sourdough starter for an ordinary loaf.

But then I’ve understood that if the room temperature is about +19 C in winter time (for my home it’s normal) these approaches don’t work well.

Nevertheless now my starter lives in a small yogurt jar: it consists of ~ 50 g fresh and strong starter. I bake with it about 2-3 times a week, so it works best for me. And by the way as I experiment a lot with sourdough starter and in order not to get confused, I give them names.
