Sourdough bread having trouble rising
Hi! I have a sourdough starter that is now almost a year old and have noticed that over the past few weeks my loaves don't seem to be rising very well at all. I was disappointed at how slow they have been. They only use to take a few hours to rise up nicely, but now they take closer to 5 hours or more and still nothing all that great. I was buying the same flour the whole time, but I did discover that the rye I was always buying before was not full rye the last time. They told me that they had an over run and I actually got half and half rye and wheat. I am not sure if that is the problem or not, but I didn't notice the problem till the last few weeks and that was when I purchased new flour. I would prefer to grind my own, but with an organic mill in our town I figure why bother. Any suggestions on why the sourdough might not be rising well anymore.
