Good old Korn is hip at last

Visit to August Ernst, the market leader in Germany
Grain or ‘Korn’ is something that is essentially German. It has been distilled for more than 500 years in Germany – and almost nowhere else. Grain is integral to what is referred to in Germany as the ‘Herrengedeck’ – a grain brandy served in corner pubs alongside a beer of some description. Marksmen‘s and barn festivals would also be far different affairs without the clear liqueur. Grain is seen as down-to-earth, as something for the people, but certainly not as hip.

Until now perhaps?
Following the craze for craft beers and various types of gin, Craft Korn, of which some promising examples already exist, is fast becoming all the rage on the bar scene. Presented in chic bottles, and steeped in a history rich in aromatic grains and craftmanship honed to perfection over many years. The company August Ernst from Bad Oldesloe, market leader in all aspects of grain brandy in Germany, is experimenting with new types – but will not say much more than this.

‘Oldesloer Weizenkorn’ – Germany‘s best selling grain brandy – is a classic beverage produced by the company. Five million bottles roll off the production line every year. A wide range of liquors, fruit brandies and mixed beverages are also produced, not just for the German market, but also for Spain, 
Israel and Japan. The company has 
already received many accolades and medals; the most recent was in 2017 when the grain brandy distillery was awarded the prize for sustained product quality by DLG (German agricultural 
society), among other awards.

The distillation process is also 
supported by HEROSE fittings and safety valves. “They have been used since the distillery was built in 1990 – and we have always been impressed with the results”, says 
Christoph Schacht, head of the distillery. As the fine distillery is fully enclosed for customs and excise reasons and cannot be accessed, HEROSE needed to design special control elements for the gate 
valves: “These are opened and closed from the outside via a handwheel to drain off the fusel oil when the need arises”, explains Christoph Schacht. There are so many different distillation stages that there are 22 of these handwheels. The handwheels and valves are up to 4 
metres apart – and this distance is bridged by spindle extensions.

How is grain brandy actually made? Stephan Röding, Head of Production explains: “Wheat, our starting product, is ground in roller mills and 
mixed with hot water: the result is referred to as ‘sour mash’. Enzyme-rich malt is added to the mash to sweeten the cereal starch. The sweet mash obtained is cooled and fermented with yeast thus forming ethanol (ethyl alcohol). The actual distillation process comes next. The alcohol vaporises and undergoes multiple distillation in order to remove undesirable odorous and flavouring substances. Water is added to the fine grain distillate with high percentage volume of roughly 96 % until a drinking strength is obtained. 
Our end product, grain brandy, has 32 % alcohol by volume and “Oldesloer 
Doppelkorn” has 38 %.”

What makes the Oldesloer grain brandy taste so good?

Head of Production Röding: “As we still carry out the 
distillation ourselves, our grain brandy 
is especially aromatic. We also use a high-quality spring water, which also makes a difference.” The company sources the wheat from 
a local farmer. Distillation only takes 
place between October and April – when grain is enough to last one year. Röding: “One side product of distillation is malt residuum. We sell that as high-quality 
feedstuff for cows to farmers. Malt residuum is however only used in the stall period. Distillation is suspended from April to October because animals are put out to pasture in this period which means the malt residuum is not required.” The company in Oldesloe is highly committed to transparency for the consumer. Röding: “As president of the Federal 
Association of the German Spirits Industry and Importers BSI, our boss Thomas Ernst is very serious about promoting alcohol consumption based on enjoyment and moderation, an approach which has also been supported since 2009 by the BSI campaign ‘Enjoy moderately’.
