Tools and Terms of Measurement: The ABCs of Beer #4
Friday, September 4th, 2015
We’re sure by now you have realised that the commercial beer-making process is a lot more complicated than people often assume. Every bottle needs to taste and look the same, every time. This not only requires specialised tools and equipment, but precision and finesse. All sorts of elements need to be accurately measured, from the temperature to the colour of the final product.
A kettle is used to boil wort.
A lauter tun is a large vessel fitted with a slotted false bottom and numerous drain pipes used to separate sweet wort from spent grains after the mashing process has been completed.
An oast house is a farm-based facility where hops are dried and baled after picking.
Alcohol by Volume (ABV) is the percentage of alcohol contained in your beer, measured by volume.
Bitterness Units is the measure of bitterness in a beer. Bitterness is derived from the amount of hops added. For example, a Castle Lager has 22 bitterness units compared to Carling Black Label’s 16.
Degrees Plato is a scale used for measuring the amount of dissolved sugar in a solution.
Lovibond is a scale used to measure colour in grains and sometimes in beer.
Original gravity is the specific gravity of wort before fermentation.
Join us next week for the 5th instalment of the ABCs of Beer – we’ll be giving you some handy terms to throw around the dinner table.
