The night's experiment

Tonight I experimented with Russian bread "Stolichny". It was baked with liquid levain. It is the GOST-bread. (GOST (Russian: ГОСТ) refers to a set of technical standards maintained by the a regional standards organization in USSR).
Levain for this bread needs 3-phase refreshing. On the first two refreshings I added a little bit of barley flour (it will be about 10% of all flour).
