EDIT: based on some feedback, I have corrected my original post. 

I set out to locate a list of protein levels in common flours, and I found a handy list, reposting for your perusal:

Flour Names & Protein Percentages

  • King Arthur Queen Guinevere Cake Flour (8.0%) 
  • King Arthur Round Table Pastry Flour (9.2%) 
  • Caputo 00 Extra Blu Flour (9.5%) 
  • Generic All-Purpose Flour (10.3%) 
  • King Arthur All-Purpose Flour (11.7%) 
  • Caputo 00 Pizzeria Flour (12.0%) 
  • General Mills Harvest King Flour (12.0%) 
  • Robin Hood All-Purpose Flour (12.0%) 
  • King Arthur Bread Flour (12.7%) 
  • Bob's Red Mill Semolina Flour (12.9%) 
  • Five Roses All-Purpose Flour (13.0%) 
  • Eagle Mills All-Purpose Flour (13.3%) 
  • King Arthur Whole Wheat Flour (14.0%) 
  • King Arthur Whole Wheat Organic Flour (14.0%) 
  • King Arthur Sir Lancelot Flour (14.2%) 
  • Arrowhead Mills Vital Wheat Gluten Flour (65.0%) 
  • Hodgson Mill Vital Wheat Gluten Flour (66.6%) 
  • Bob's Red Mill Vital Wheat Gluten Flour (75.0%) 
  • Gillco Vital Wheat Gluten Flour (75.0%) 
  • King Arthur Vital Wheat Gluten Flour (77.8%) 
FYI, this came from a very handy page & calculator I came across at
The reason I was interested in this is because I wanted to find out how much my protein would be boosted by adding vital wheat gluten to my flour. 
I usually use KA All Purpose, which has 11.7% protein. To supplement, I planned to use Bob's Red Mill Vital Wheat Gluten Flour. 
  • 1 cup KA AP flour weighs  about 125g. If 11.7% is protein, then there is about 14.63g of protein per cup of this flour
  • 1 tbsp of Bobs Red Mill Vital Wheat Gluten weighs about 8.5g. If 75% is protein, then 6.375g of protein per tbsp of this flour.
  • 1 cup KA AP + 1 tbsp Bob's Red Mill Vital Wheat Gluten = 21g TOTAL protein
  • 21g of protein / 133.5g total ingredient weight = .161, or 15.73% of protein in the flour mixture

You can use this same method to calculate the adjusted protein in your flour. 


What's interesting to me is that at the recommended dosage, adding 1 tbsp. of Bob's Red Mill gluten to every 1 cup of KA flour would make an extremely high protein flour, higher than what is typically commercially available. I wonder if it would make it totally unusable & gummy?

Then again, if you had a relatively weak, generic AP flour (9% protein), then 1 tbsp per cup would probably bump you to a very respectable 13.2% protein level, close to that of KA Bread Flour. For those that have actually tried this technique, I wonder if it actually performs in a similar way (e.g., similar to KA Bread flour) or do other flour factors (such as ash content, type of wheat, etc) play more into the overall performance of the flour and resulting bread?

Artisan baking contests

February 10, 2011 - 12:42pm -- ssor

I recall reading somewhere that the major baking contests require that everyone bake with the same brand and grade of flour.

The rationale being that anyone can make good bread with very good flour but it takes more skill and experience to make good bread using mediocre flour. The result of this little bit of information has caused me to buy only house brand unbleached flour and to concentrate my efforts on improving my technique.

Costco ConAgra Harvest Flour

February 2, 2011 - 11:53am -- Kitchen Barbarian

OK so I've been having an AWFUL time trying to make my bread come out right and I finally found out what's wrong.

ConAgra Harvest All Purpose Flour is about the same protein content as biscuit mix.  It's barely above a cake flour. At least what's available in MY area is.

I had to call ConAgra to get this information and if you are in some other part of the country it's going to be different.  Unlike King Arthur, Con Agra does not mill their wheat to meet any particular definition of what we would typically think of as "bread flour" or "all purpose flour".

Bread authors have slowly nudged me toward buying some organic and stone ground flours to experiment with. Exploring the web and other sources led me to hone in on War Eagle Mill (WEM) in Rogers Arkansas for my source for they have a good reputation and are closer than most. When they ran a 20% off sale with free shipping for orders over $100 I had to give it a try so I ordered 25 pounds each of organic AP and BF (roller milled), and 10 pounds each of stone ground organic WW and White WW. The flour came Wednesday so I cranked up the oven to make Tartine yesterday. Photo below.

I only used the BF and WW and the dough is mostly BF. The BF has more aroma of wheat then the KA AP and BF I normally use. The BF is about 11.5% protein according to War Eagle. The WW had a wonderful texture and aroma also. The dough seemed a bit touch dryer than KA for the same hydration - but softer. During the bulk ferment the "wheaty" aroma of the flours really grew evident. Tasting the dough revealed it to be sweeter and "grassier" than KA. The dough responded very well to S&Fs but, despite its drier feel, remained a tad stickier than the KA AP and stuck to the bannetons - and also flowed rather dramatically on removal from the bannetons, giving a rather flat disk in my cloche. Oven spring was very good and the expansion almost hid the folds from the banneton sticking. Flavor was wheatier than KA.

Preliminary conclusions: The WEM BF is similar in behaviour to KA AP but with more nose and more color. The aroma gives the bread a "lighter" taste profile. The crumb has a bit less bite than the same bread make with KA AP and WW. The WEM WW appears lovely and worked very well in the role of supporting flour. I think I will next try it or the white WW in a miche - or maybe one of each.  Given the WEM AP is supposed to be about  a percent lower in protein I am guessing I won't use it much but I will try it in Banh Mi for I have been struggling to get the crumb as delicate as I want. Overall I was pleased with this initial foray into organic and stone ground flours.

The loaves were made following the Tartine recipe with one exception. My starter is less sour so I use 50 grams of starter to make the 400 grams of levain in the first step. Then I used 200 grams of the levain and followed the recipe. Key difference was that my kitchen was around 67F so the bulk fermentation ran about 7 hours. The Hamelman videos at KA on loaf forming reinforced the need for the dough to be airy and I gutted it out. After shaping I moved to a warming drawer to accelerate the proof. The loaf I cut had a small peak at the top and I guessed it indicated larger holes and that was verified. The other loaf will be more uniform. I tried moving the preheat down to 475 with the bake at 440 and the loaves came out a bit light for my taste (internal temp 210). The surface has a duller finish than I like because I used rice flour in the flour mix to coat the banneton since the dough was pretty sticky. More photos follow.

Eden bulk flour

January 22, 2011 - 10:29am -- bobchristenson

I am looking to buy bulk flour (all purpose and wheat) and Eden mills it in my home state of Michigan. I found this and am wondering if anyone has purchased it:

The description says it's all purpose, whole wheat, and bread flour. Obviously it's not all of them. I'm wondering if anyone knows which it would be considered?

Thanks for any feedback

Just made a trip out to Central Milling, which is actaully called "Keith Giusto Bakery Supply". They have moved into a new location. 755 Southpoint Blvd, Petaluma, CA. 866-979-2253

They have a very large selection of organic bulk flours. Now, you can call ahead, and they will pack 5lb bags. They ask that you please call ahead though, otherwise, you will wait for some time. If you are buying in 25 or 50lb bags, no problem.

Under construction, is a Bakery School, on site, that will be open soon.

Please email me your contact, if you are intersted in bulk flour. We were told that if enough of us order, they will deliver to SF, as they deliver to the Ferry Bldg twice a week.

Baking powder taste in bread flour

January 11, 2011 - 5:52am -- glakritz

First, some of you may remember, just before the holidays I posted about not being able to get bread flour here in the small villiage I live in in Central America.

I was able to make a connection the other day and score 100 pounds of what is referred to as Strong Flour.  The problem is that all the baked goods I have tried with it have a strong baking powder taste.  Does anyone have a solution to masking the taste?

King arthur flour

December 27, 2010 - 12:46am -- LT72884

I found a store about half a mile from my house that caries King arthur AP and 100% red wheat flour for 3.16$ per 5lb bag. Is KA a good brand? should i replace my Goldmedal AP flour with KA flour? I follow the Artisan bread in 5 a day and healthy bread in 5 a day, but i have been using goldmedal for this process. Will the red wheat KA flour work as a replacement for goldmedal whole wheat?


thanx guys
