Does that not conflict with the Purity Law? This pertains to their domestic marketed beers only. What is exported can have anything in it, even Red Dye #1.
Hofbrau, Becks, Spaten, Paulaner, plus the other main-line German Breweries most likely do not add coloring.
Can you post evidence that would prove otherwise?
Found the following, but to me it is still not acceptable.
As is common in wine and liquor, the color of beer may be adjusted upward (toward higher color) by the use of a number of compounds. The most important is caramel color. See caramel color. A related product is Farbebier (German for “coloring beer”), a product developed in Germany as a coloring agent allowed by the Reinheitsgebot (German purity law). See reinheitsgebot. Although totally undrinkable, Farbebier is technically an extremely dark beer brewed with black malt exclusively, and therefore it may used without label declaration in most countries.
There are two normal reasons a brewer may use coloring agents in beer. The first is as a color corrective, used in small dosages as a final correction of the color of a wide range of beers. But it may also be used as part of the actual construction of a beer. As coloring agents are—at normally used concentrations—virtually without aroma or flavor, they can be used for producing dark beers with much less roasted aroma, flavor, and taste than would result from using dark malts to achieve the same color. An industrial brewer may thereby use a form of food coloring to give a beer the appearance of rich flavors where none may actually exist.
So revered is the Reinheitsgebot that the German Brewers’ Association applied in December of last year for the United Nations Educational, Scientific and Cultural Organization (Unesco) to give it protected “world heritage” status.
"We made a survey [in Germany], and asked people if they wanted to have beer brewed under the purity law, and more than 90% said they wanted to stick to the purity law.
“There are some things that Germany stands for and one of them is German beer… we want to show the world that we have a very old tradition.”
