°WK or degrees Windisch-Kolbach is a unit for measuring the diastatic power of malt, named after the German brewer Wilhelm Windisch and the Luxembourg brewer Paul Kolbach. It is a common unit in beer brewing (especially in Europe) that measures the ability of enzymes in malt to reduce starch to sugar . It is defined as the amount of maltose ...
A malt has a diastatic power of 100 °L if 0.1cc of a clear 5% infusion of the malt, acting on 100cc of a 2% starch solution at 20°C for one hour, produces sufficient reducing sugars to reduce completely 5cc of Fehling's solution. Note that the amylases used in brewing reach their peak efficiencies around 66 °C.
A basic formula [4] to calculate beer strength based on the difference between the original and final SG is: A B V = 131.25 ( O G − F G ) {\displaystyle ABV=131.25(OG-FG)} The formula below [ 5 ] is an alternate equation which provides more accurate estimates at higher alcohol percentages (it is typically used for beers above 6 or 7%).
United States standard drinks of beer, malt liquor, wine, and spirits compared. Each contains about 14 grams or 17.7 ml of ethanol. A standard drink or (in the UK) unit of alcohol is a measure of alcohol consumption representing a fixed amount of pure alcohol.

Traditional floor malting at Highland Park Distillery in Scotland. Malting is the process of steeping, germinating and drying grain to convert it into malt.Germination and sprouting involve a number of enzymes to produce the changes from seed to seedling and the malt producer stops this stage of the process when the required enzymes are optimal.
