Oatmeal Graham Flour Sourdough Pullman Bread

I received a sack of graham flour for Christmas.  It is from Burkett's mill.  If you read up on graham flour you usually read that it whole wheat ground more coarsely than the usual WW.  If you find the right site, it will tell you that the endosperm is ground finely and the bran and germ are ground coarsely, I think the flour I have must be the latter.  It's color is lighter than the water wheel-stone ground flour I have, with larger flecks and dark bits.

For this loaf I cooked some rolled (porridge) oats in the microwave, and added them to the dough. The flour content is 70% bread flour, 30% graham flour, and the uncooked oats weighed 20% of the total flour.

Ingredients
=========
70% bread flour (KA)
30% graham flour (Birkett's Mill)
20% oatmeal (rolled oats uncooked weight)
50% water (for cooking oatmeal)
60% other water
36% starter (100% hydration)
2.2% salt

---------------------
370g flour (exclusive of starter)
990g Total dough weight

It is always hard to know how much of the water in cooked grains, scalds, etc. will contribute to the effective hydration.  In this case, I had trouble wetting all the flour so I added some water.  Apparently I added too much because I ended up with a thick, pasty batter.  A few sets of coil folds over the next 2 1/2 hours added some strength, but I still had to scrape the dough into the Pullman pan.

The loaf rose well in the end and has a surprisingly open crumb.  The crumb is a little delicate; the flavor is richer than the usual WW, and a little sweet, which I think is partly down to the graham flour and partly to the oatmeal.

I baked the loaf for 50 minutes at 350 deg F/177C without the lid.  The internal temperature had reached 208 F/97.7C but the loaf was pale and I knew it had a lot of moisture still to give off.  So I baked it at 400 F/204C for another 10 minutes.

Overall, a very nice loaf.
