1) In my country we have following types of wheat flour - T-400/T-450 and these 2 are white, T-500/T-550 (also white), T-850 (brown) and T-1100/T-1600 (black), however when I googled this I didn't find anything and it seems that there is no such thing as "black wheat flour" so I'd like to know what is it's name in Europe and USA (black wheat flour is wheat flour with high ash content, in my country numbers after letter T represent ash content multiplied by 1000)

2) How are all these wheat flours produced?As far as I know wheat flour is made by crushing wheat grains.

3) What is the difference between whole wheat flour and black wheat flour (T-1100/T-1600)?

  • I've never heard of these, what country are you in? – GdD Jul 9 '15 at 12:25
  • These types of flour exist in Croatia, Serbia and Bosnia (and maybe in few more countries near these). – user3711671 Jul 9 '15 at 12:40

    Welcome to the site. When you have 3 questions, please ask them separately. That way people who can only answer one, can just answer one. – Lyndon White Jul 9 '15 at 13:35

    It is indeed important to have different questions asked separately, but I think that in this case, the questions are very similar, in the sense that if they were asked and answered separately, each answer would share a lot with the other two. What we need is simply a better title, I'll try to think of one. – rumtscho Jul 9 '15 at 14:39

Flour types are quite different in various countries, but yes, all flours are basically made from crushing grains (wheat in this case).

A grain mainly consists of three parts:

enter image description here Source: http://www.californiawheat.org/industry/diagram-of-wheat-kernel/

  • The bran.
    The outer layer of the grain.

  • The endosperm.
    The white inner part that we tend to associate with flour.

  • The germ.
    The sprouting section. Often removed in flours for longer shelf life.

So when milling grains, the parts of the grain are separated, for whiter flour (that's the lower numbered types, the number actually giving the mineral content and indirectly indicating the fiber content.), the bran and germ are mostly removed, "brown" and "black" flour (middle to high number range) increasing amounts of the bran are kept,resulting in a higher fiber content.

Whole grain is - as the name implies - made from the whole kernel (but quite close to "black" / 1600).

As you noted, the "numbers" (= mineral content) typically sold in stores are not consistent in European countries, but the pattern is always the same. (In France, the numbers seem different, but are basically the numbers you know divided by 10.) If your recipe calls for a specfic "number", you can "mix" "lower numbered" and "higher numbered" flours to get the desired strength.

For simplicity the lighter types are sometimes labeled according to their use: Cake flour / all purpose flour / bread flour (-> increasing "numbers").

The US has a slightly different system, here flours are characterized by their protein content and labeled according to use. if I remember correctly there was some kind of "substitute chart" here, but I can't find it at the moment.

  • There is no good substitute chart for US flours, because their protein difference comes from using different types of wheat (hard vs soft) while the European difference comes from using different parts of the kernel, so a European high protein flour automatically has other elements and behaves differently from a US high protein flour. – rumtscho Jul 9 '15 at 14:44

I concur with the information @Stephie has provided. However, there is a 'black wheat flour' that is widely used in France and other European countries. It is actually made from buckwheat, which by definition is a grain but not wheat at all.

From this Wikipedia article :

The seed coat is green or tan, which darkens buckwheat flour. The hull is dark brown or black, and some may be included in buckwheat flour as dark specks. The dark flour is known as blé noir (black wheat) in French, along with the name sarrasin (saracen).

More info and history from Behind the French Menu :

Farine de Blé Noir, Farine de Sarrasin or Blé noir – Buckwheat flour. This is a flour with a distinctive, mild, nutty taste; the flour’s French names translate directly as black flour or the flour of the Saracens. The darker color comes from the seed’s coating and when some of the coating is left in the flour making process it is that coating that gave the flour its color. Buckwheat is gluten free.

The French name for buckwheat flour, Farine de Sarrasin stretches back to the crusades. During the crusades the French first met up with the dark skinned Saracen warriors and also were introduced to their dark buckwheat flour. They took the flour home and among the flour’s various names is the name of their Saracen foes; today that would not be politically correct. The galettes de blé noir, crêpes, pancakes of buckwheat flour, are traditional in Bretagne, Brittany, but, you will find buckwheat flour in use all over France.

From Cook"s Info , buckwheat flour has a 2% mineral content.

Nutrition

Buckwheat Flour is approximately: 63% carbohydrate, 11.7% protein, 2.4% fat, 9.9% fibre, 11% water and 2% minerals.

  • You might be comparing apples and oranges here. While buckwheat is "blé noir" in French, other languages have less misleading terms: "hajdina" (Hungarian), "bovete" (Swedish), "Buchweizen" (German)... But bread is colloquially categorized by the "darkness" of the flour, many languages where higher typed flour is used have equivalents of "white bread" and "black bread". – Stephie Jul 9 '15 at 20:38
  • @Stephie I understand your point and it is valid, and I am not disputing the information you have provided. However, I think that this information is also relevant. I searched extensively and, for the term 'black wheat flour', all results came back as either buckwheat or the French 'Farine de Blé Noir'. I am just offering this as one explanation of the term. I don't know how the term is interpreted in that part of the world but, per your information, the answer to Q3 would be that there is no difference. – Cindy Jul 9 '15 at 21:05
  • "Black wheat flour" is the word-by-word translation for "Farine de Blé noir", so if you googeled this "connection" is likely, but not what OP would use (heljda or hajda). As for Q3, they are similar, but not identical. – Stephie Jul 9 '15 at 22:04
  • @Stephie Heljda is Croation for buckwheat. – Cindy Jul 10 '15 at 15:37
