What can I say, I like big loaves.  I have made the Tartine Country bread a number of times in all sizes, from 500 gm to 2 kg, and am always happy with the results.  I refreshed my starter when I returned from a week away with the intention of trying the whole wheat loaf as well.  On my last visit to Central Milling I picked up a 5# bag of Acme Organic Whole Wheat flour, so what better bread to test it on.  I pretty much followed the method in the book, with a small deviation because I forgot to hold back the required 50 gm of water to add with the salt after the autolyse, so I had to add some extra water.  The formula was supposed to be 80% hydration, and the extra water took it up to 83%.  The formula is quite basic:

Levain          200 gm    20%

Water           830 gm    83%

WW flour    700 gm     70%

AP flour       300 gm     30%

Salt                  20 gm      2%

I made a double batch and shaped them into 1 miche at 1950 gm and three smaller boules at around 700 gm each.  The bulk ferment was about 4 hours at a controlled 74˚F with S&F at 30, 60, 90, 120 and 180 min.  After shaping, I retarded the miche and one smaller loaf overnight (about 16 hours), and continued proofing two of the smaller loaves for 3 hours.  Baking was on a stone heated to 500˚F which was reduced to 460˚ when the boules were peeled into the oven.  Steam for 15 min. then turn on the convection to 425˚ for 20 min. more, rotating as necessary.  For the miche, the convection temperature was 415˚ and the convection bake time was 35 min. 

The loaves showed lovely bloom and grigne.  I have been playing with different scoring lately, and I like the effect using two interlocking half-circles.  A bit cumbersome to do on the large loaf, but it's a nice look.  I think the bake times could have been a bit longer.  Though the loaves registered over 205˚ and were left in a cooling oven with the door cracked open for 10 min., I didn't get the nice singing and crackling crust like I do on the Country Loaf, which I suppose is due to the higher hydration dough and not being baked out completely. 

The crumb on this bread is sublime - airy and with a fairly soft chew.  The flavor is nutty and wheaty with a distinct tang on the retarded loaves (I didn't get to try the others).  Curiously, the 2% salt seemed a little on the light side.  This photo is the crumb of the smaller loaf - I'll post the miche once I cut it.  The final size of the miche was about 10 inch diameter and 4 inch tall at the dome.
