SF Dough, ferments doesn't sour

Toast

I went through the process at the suggested site "abreadeducation" ,   waited and checked daily after a week.  It did ferment   lots of small bubbles  but no sense of sourness at least in the odor.   Before I try baking with it,  should I detect some odor of "sour" or will this only show up in the bread?  I want it to be truly SF bread  nice and tangy.

10 days to 2 weeks for a new SD starter to be ready to bake a loaf of bread but it twill be slow and no where near it will; be in a month.  Once it matures the SD smell will be there.

is at least 75°F or 24°C for proper SF SD growth.   

you will have to taste it to detect sourness
