starter not rising noticably
My 3+ month old starter doesn't seem to rise much lately. It does a little when it's left out, but it doesn't seem to at all in the fridge. My breads are rising fine and taste sour or not depending on how I treat them, but I wonder if the starter is as healthy as it should be.
When it is on the counter I feed it twice a day as it gets very foamy, fluffy and rises a bit and falls. In the fridge, I feed it about every three days or so, although sometimes sooner because it develops hooch.
I feed it flour equal in volume to the starter but with a bit less water to make a fairly thick batter. Mostly I feed it KA AP, but sometimes add a bit of organic whole grain rye.
Since it seems to work well, I've assumed things are fine, but then I realized I could be wearing it down or something without knowing it and I'd be sunk.
I guess the short question to this long post is- If a starter doesn't rise after a feeding is it still healthy?
