Yes, it takes time for sourdough to mature. You can help it along by adding potato starch and organic apple cider with the mother and using it more often.So what was it you were doing that made it Not have the sour taste?
Mine is young, only a month or so old and gluten free too, but I'm not getting much of that sour taste either. Not sure if it's that lack of age or being GF.
There is no commercial yeast in it at all. It bubbles well and does have a mild sour smell. Whenever I take some out and feed the remainder they are both very active, however it does not give great rise to baked good. But, GF SD does not rise as well as regular anyway according to research.
@ronott1 any ideas? Does it just need more time to mature?
