WSD

Sourdough, and Yeast Water Combinations  From Sour to Sweet and Way Back Again
Previously, I posted details on the loaf I use as a 'standard', for purposes of testing. Link:A Standard KISS Loaf, or Keep It Simple Smiley The Fresh Loaf
In that post, I gave a table for three basic types of loaf - White Sourdough [WSD], Yeast Water Levain [YW], Sourdough & Yeast Water Hybrid [SD&YW].These three basic types were shown with there formulae given in two batch sizes, 680g and my 'standard' 478g
In this post, I provide photos of these 3 types, as baked in my standard nominal 478 gram size. At the end is a fourth type loaf, which I will simply call "Aged-SD". The four loaves generated a range of flavors, "nice tang", "fruit and sweet", "sweet with a mild tang", and finally "Strong tang with sweet overtones".

The first images are of the "Straight Sourdough" loaf.  It gave a very nice, mild SD tang to the loaf.

This second set of images is from a totally Apricot YW loaf.There was no sign of any SD tang, nor any apricot flavor, however, there was a very nice flavor with a fruit-like sweetness, and the slightest hint of the type of "tang-like" taste one might detect in an apricot itself.  

This third loaf was a combination of the same sourdough culture used in the first loaf, and the apricot yeast water culture use in the second loaf.

I found the flavor was all I hoped for, a lovely blend of the sourdough tang and sweet, fragrance of the fruit with a slightly different tang from the Apricot YW.

This forth, and final loaf offers a flavor, not unlike the third loaf, but with a "jacked up" sourness. The "Aged-SD", is explained in the PDF copy of my baking log's detail comments, which you can access from Google Docs at the following link:Y-110610-07_Aged-SD+SD&AprYW_478 [Photos]_110611-1115.pdf - https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0B_MScoZfDZkwZmU4ZGIyM2EtMmE3OS00OWY5LWI0YjAtYjRkN2VmZTQwYzli&hl=en_US

Extremely good oven spring. Of course, the final rise went 6 hours + 45 minutes, and it was 40% bread flour in the dough. Nonetheless, the 11% levain, which was this first testing of Aged-SD surly didn't cut into the levain's ability to leaven this loaf. The top of crust was strong and very chewy. If you like a good good tang with note of apricot tang, but without identifiable fruitiness and a soft touch of sweetness, then, you would like the loaf's flavor. Crumb was more open than my recent enriched sandwich breads, but still more than tight enough to be an excellent sandwich and toast loaf.   The levain method of adding Aged-SD most definitely accomplished my desired objective of combining SD and YW merits into a Hybrid Sour Sweet and Sour loaf.
