For the amateur brewer in a hurry, we present seven important ready-reckoner tables, covering attenuation, alcohol content, hydrometer correction and yeast pitching rates.
All files are in PDF format.
The tables were produced using the online calculators at Pint.com.au and MrMalty.com.
Apparent Attenuation
An approximate measure of the extent to which wort sugar is converted into alcohol
3 pages. Read OG (1.030-1.092) against FG (0.998-1.025).
