After some discussion in recent threads, I decided that it's high time I tried out shorter bulk ferments. My guiding principle has been that the longer the flour is hydrated, and the longer it's fermented, the better the flavor. So I usually let bulk ferment go on to more than double, sometimes triple, the original size. This usually gives me a fine, fairly uniform crumb, which may have large pores or smaller ones depending on hydration, grains, all these sorts of things.
This practice has served me well, and I like that kind of crumb, but I've been interested to see how a shorter bulk ferment could change things. Some people only let the dough rise by 1/2 or 1/3, for example. This bake is my first experiment. As a bonus, I measured the pH with my new Hanna meter.
Here's the crumb shot, then the details:
You can see that there is a wide range of pore and cavity sizes, and in the larger ones you can see some nice gelatization. The crust is gorgeous, and the height and oven spring were excellent. The crumb is well open for a 72% hydration loaf. I'm very happy overall.
This loaf uses mostly all-purpose flour along with some malted barley and Irish-style whole wheat flours. This made for a soft crumb. It might be a little too soft for the crust, which is thin, flakey, and a little crunchy.
Formula (flour and water are totals including starter's flour and water) *
=======
10% - malted stone ground barley flour
10% - KA Irish-style whole wheat flour
80% - Gold Medal All Purpose Unbleached
72% - water
20% - starter (100% hydration, made with bread flour)
2.2% - salt
* Total flour was 400g.
Process
=======
8:30 AM - Rough mix of all ingredients
9:00 - knead and stretch
9:55 - 1st S&F, between wet hands
10:45 - 2nd S&F, between wet hands
12:05 - 3rd S&F, on bench with a little flour
1:30 PM - 4th S&F, on bench
3:30 - shape loaf, proof freestanding covered with plastic wrap**
4:55 - bake
** Dough had risen by roughly 50%, compared with my usual 2.5X - 3X.
After the 3rd S&F the dough felt wonderfully silky, and was very extensible. I decided to do a final S&F to reduce this extensibility.
Bake Profile
=============
- Preheat oven with baking steel to 450 °F
- Uncover loaf last 15 minutes
- Slash, insert into oven
- Throw 12 oz tap water on steam tray, block vent for 1 minute***
- Turn temp to 300 °F for 15 minutes
- Turn temp to 425 °F
- Total bake time: 40 minutes.
*** The oven leaks steam so fast that hardly any is visibly coming out of the vent after a minute.
Here is a graph of the pH vs time. Don't pay any attention to the first point looking lower than the second. I just didn't write down the second digit of the reading, which I did for all the others. I'm sure the first point was the same as the second one.
Oh, yes, the taste is rich, mellow, a bit buttery. All in all, a successful experiment, I'd say.
