them old overfermentation blues

a round loaf of rye bread

I’ve been feeling uneasy these days, and, perhaps in solidarity, my starter has, too. For a few months now, it’s been highly acidic which has cut down on its ability to promote yeast growth. For my usual deli rye – 45% whole rye/10% whole spelt/45% bread flour -- I mixed the levain and, after 12 hours on the counter, it was clear that it had not progressed in the right direction. It felt and looked dead -- just a non-responsive grey lump.

I mixed the dough anyway, but after its usual 3 hours on the counter, it, too, felt inert – little rise, almost no stretch. So I left it out another night – at which point it had become more of a batter than a bread dough. Unfortunately, I didn’t have time to try to bake it right then. So I put it in the refrigerator for an additional 12 hours. Last night – after 36 hours of fermentation for a bread that I have previously baked, from start to finish, in 12 hours – I took it out of the fridge. The chilled batter was seriously gooey but I was able to shape it and bake it.

And, now that I’ve eaten a few slices, I have to say: The sourness is pronounced but pleasing, and while I miss the loft of an appropriately fermented bread, the crumb is a bit softer and more pillowy than usual and the crust is crispy and delicious (though not as amazingly sweet and crispy as it would be with more controlled fermentation).

What can I tell you? Reports of my dough's death were greatly exaggerated. And them old overfermentation blues sometimes ain’t all that bad.

Don’t give up is the theme here I think. You definitely have a beautiful loaf inside. That’s quite an epic story . I’m glad it turned out so well. I hope your starter gets back on an even keel. 

I’ve had 2 incidences of starters getting unhappy and making a new one solved the problem. Maybe it’s time. 🙏

My starter lives in the refrigerator and I recently realized that the fault is not in the starter but in my partner life accomplice (🤣🤣🤣🤣🤣!!!!!), who is very sensitive to small noises and turns the fridge off for long periods of time when she is home, causing wild temperature fluctuations that angry up the starter. All fridges make a little noise, and, as Davey1 put it, adjusting is relatively simple. So that's what I've done -- adapted to the idea that my timings will be wonky and my breads will be wacky. -- Rob

Our Fischer Paykel fridge is completely silent. Even when standing right up next to it you can’t hear it. Ice drop would be the only sound and it’s muffled and very infrequent. 

Yikes is all I can say about turning off a fridge. 🙏

That looks like good bread to me, Rob. I'm sure it must taste fabulous. At least now you've figured out why your starter's behaving this way! Perhaps adjusting the levain ratios and duration will help if you're using the starter when it's probably rather acidic. Alternatively, I find that the biga lends itself extremely well to temperamental starters.
