List of brewing companies in Germany: This is a list of brewing companies in Germany.  Beer is a major part of German culture.  For many years German beer was brewed in adherence to the "Reinheitsgebot" order or law which only permitted water, hops, yeast and malt as beer ingredients.

Canadian Wheat Board: The Canadian Wheat Board (French: "Commission canadienne du blé" ) was a marketing board for wheat and barley in Western Canada.  Established by the Parliament of Canada on 5 July 1935, its operation was governed by the Canadian Wheat Board Act as a mandatory producer marketing system for wheat and barley in Alberta, Saskatchewan, Manitoba, and a small part of British Columbia.  It was illegal for any farmer in areas under the CWB's jurisdiction to sell their wheat and barley through any other channel than the CWB.  Although often called a monopoly, it was actually a monopsony since it was the only "buyer" of wheat and barley.  It was a marketing agency acting on behalf of Western Canadian farmers, passing all profits from its operation back to farmers.  Its market power over wheat and barley marketing was referred to as the "Single Desk".

Beer: Beer is the oldest and most widely consumed alcoholic drink in the world, and the third most popular drink overall after water and tea.  Beer is brewed from cereal grains — most commonly from malted barley, though wheat, maize (corn), and rice are also used.  During the brewing process, fermentation of the starch sugars in the wort produces ethanol and carbonation in the resulting beer.  Most modern beer is brewed with hops, which add bitterness and other flavours and act as a natural preservative and stabilizing agent.  Other flavouring agents such as gruit, herbs, or fruits may be included or used instead of hops.  In commercial brewing, the natural carbonation effect is often removed during processing and replaced with forced carbonation.
