The actual measurement was by saccharometer (i.e. hydrometer) correcting for temperature by a calibration scale or else by a special brewer's slide rule. [7] An average strength first running of 1864 would be 30 pounds or 1.083 OG. [a] [8]
Knowing the amount of extract in 100 grams (3.5 oz) of wort before fermentation and the number of grams of extract in 100 grams (3.5 oz) of beer at its completion, the amount alcohol (in grams) formed during the fermentation can be determined. The formula follows, attributed to Balling [1]: 427
Pilsner Urquell, the world's first pale lager and ancestor of today's Pilsners. Pilsner (also pilsener or simply pils) is a type of pale lager.It takes its name from the Bohemian city of Plzeň (German: Pilsen), where the world's first pale lager (now known as Pilsner Urquell) was produced in 1842 by Pilsner Urquell Brewery.
Diacetyl. Diacetyl is a chemical compound produced in yeast during fermentation and later reabsorbed. If the external ambient temperature during fermentation is lower than 26 °C (79 °F), diacetyl is absorbed insufficiently, resulting in a threshold of less than 0.04 mg/liter in beer, which gives the beer a mouthfeel similar to cream cheese.

This is called a limited calibration. But if the final measurement requires 10% accuracy, then the 3% gauge never can be better than 3.3:1. Then perhaps adjusting the calibration tolerance for the gauge would be a better solution. If the calibration is performed at 100 units, the 1% standard would actually be anywhere between 99 and 101 units.
Four Seger cones after use. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials in a kiln. The cones, often used in sets of three, are positioned in a kiln with the wares to be fired and, because the individual cones in a set soften and fall over at different temperatures, they provide a visual indication of when the wares have reached ...
Pilsner Urquell (German: [ˈpɪlznɐ ˈʔuːɐ̯ˌkvɛl]; Czech: Plzeňský prazdroj [ˈpl̩zɛɲskiː ˈprazdroj]) is a lager beer brewed at Asahi Breweries' Pilsner Urquell Brewery in Plzeň (German name: Pilsen), Czech Republic.
"Fruity esters" may be formed if the yeast undergoes temperatures near 21 °C (70 °F), or if the fermentation temperature of the beverage fluctuates during the process. Lager yeast normally ferments at a temperature of approximately 5 °C (41 °F) or 278 k, where Saccharomyces cerevisiae becomes dormant.
