controlling overproofing
I'm beginning to think my yeast is on steroids...
Given my hectic schedule, what with work and home and hubby and 3 kids going at least 4 different places, I have often stowed dough in the fridge to buy some time...as well as develop the flavors. However, I've noticed a pattern that I haven't seen discussed on the forums yet:
If I put the dough in the fridge before first fermentation (knead it and fridge it), I get very little rise in the fridge. But if any rise has happened at room temp and then I fridge it, either during first fermentation or proofing, I get overdevelopment...by the time the dough has come to room temp again, it's huge and I might as well degas ( the action, not the artist!) and shape from scratch, otherwise it's impossible to slash and I get almost no oven rise.
Doesn't matter if it's yeast, or yeast-starter combo. I do the combo because my starter, altho bubbly and tasty, has never really risen...and I seldom have the extended stretches of time to let a straight starter do it's thing...but this will be another posting.
So...is it my fridge? (Which has been having it's quirks now, as well!) I store the dough on the bottom shelf--it's a bottom-freezer version--which is coolest.
Am I using too much yeast/starter? If straight dough, yeast is typically 2 tsp for a 1 1/2 to 2 lb loaf; if yeast-starter, I use 1 tsp yeast and about 25-30% starter for the same size loaf (about 4-5 c flour). I am basing the starter percents on The Metropolitan Bakery Book (Metro. is a Philly-based artisan bakery) which suggested using 30-40% starter for max flavor and keeping quality. And since I had a bathtub full of the stuff...
Are there other issues I should be aware of?
Should I work on my organizational skills, developing a schedule for proofing, retarding, etc? In my earlier life, I was scheduled rigidly, but having been knocked around by life and being married to Mr. Spontaneity, I've lost that ability ;-). The thought of reverting to a schedule makes me cringe, but if I have to for the sake of good bread...!

Windischgirl,
I don't think anything is wrong with your yeast or your refrigerator. I have the exact same experience if I leave the dough out too long before stashing it in the fridge.
I think that it simply takes a long time to cool dough in a typical 40-50F refrigerator. If you pop it in immediately after you're finished kneading (and have used ice water instead of warm water), then the dough is already close to 40-50F, so the dough never has a chance to rise. However, if you start with warm water and give the yeast a head start of, say, 20-30 minutes, then by the time the dough has cooled from 75-80F, the yeast have already had plenty of time to do their thing.
So, I would recommend using ice-cold water and putting the dough in the fridge immediately after kneading.
Good luck.

Joseph, thanks for the reassurance! (My fridge actually has other issues--waiting on parts--but at least I know it's not after my bread!) I also appreciate the explanation...what you're describing makes sense to me.
I use filtered water from the fridge, so it's about 40F to start...but maybe if I time things a bit better and retard right away...or maybe after de-gassing...the dough should behave itself.
I have not been able to use tap water because ours is so hard...it actually stunted the growth of the yeast, and I have a white crust on the pan I use for steam (thank goodness for vinegar or I could mine the lime off...hmmm...wonder if there's a market?)

Hey Tad: You may be right, I amy need to fiddle with the temperature a bit more. I do have a lovely digital thermometer...but I also have an old house so ambient temp tends to fluctuate depending on the outdoor temp. When I started my sourdough it was January and my house was 65F (59F at night). Come July it will be 90F+, (and I am carefully reading those posts about grilling my bread!). I guess I need to develop some patience and make it worth my while to heat my water if I'm able to bake that day, and maybe being more conscious of the time if I'm mixing dough and it needs to ferment.
One of my goals of the retard is to develop flavors and improve bread quality; but the other is dealing with life's little disasters...the kid who needs a run to the store or the ER at the last minute, or the hubby who says..."Honey, can you wash? I've got a trip tomorrow..." So into the fridge goes the dough and I hope for the best...
I will give the thermometer a try. Maybe I should also be in the market for household staff ;-) Any takers? You will be paid in improved bread!
WindiWindi,
What a coincidence. I made walnut-sourdough bread this weekend with 20-25% whole wheat. The formula I am using asks that I keep the dough out at room temperature for about 2-4 hours after I am done shaping and before I refrigerate. I had a hunch that I'd be overproofing at the end of the process, because I could see a lot of rise in the dough already before I put it in the fridge. The next day, I found a fully grown monster in my fridge. I still proceeded with getting it to warm up for about an hour or so before I scored. Well, not to my surprise and just like a symbol of my efforts partly going down the drain, there was so much deflation. I proceeded with baking and got minimal oven spring. The flavors were still there (as commented by family and friends) but not the expected texture and crumb...
Next time, I will be sure to record my temperatures as suggested and put the dough in the fridge right after shaping. I have no idea how things will change when the room temperatures soar up to 80 - 90 degrees here in summer.
Thanks for sharing... Hazim
