Glossary
Gushing
The spontaneous and sometimes vigorous overfoaming of bottled beer when a non-shaken bottle is opened.
Strike water
The water which is used to mix with the grist at mash in.
Grant
A smaller open-topped vessel placed between the lauter tun and boiling kettle, through which the wort is run during the sparge. It allows the brewer easy access to the wort which is being run off, such that it can be monitored both visually and with various brewing tools such as a thermometer, hydrometer, and pH meter. Most homebrewers do not employ a grant. The grant also allows for a buffer zone between a pump and the lauter tun. If the pump were pulling directly on the lauter-tun, it could compact the grain bed and lead to a stuck sparge. But if the beer is allowed to gravity-flow into the grant, and then the pump sucks on the grant, this problem is avoided.
Grain bill
This is the term used to refer to the total amount and types of grains used in a particular beer recipe. One of my favorite beers has a "grain bill" consisting of 7 lbs 2-Row, 1 lb Malted Wheat, and 1 lb rice.
Gravity of beer
A characteristic of wort. It is measured in percents or degrees of Balling. The latter is a percentage of a mass of extracted substances (in grams) dissolved in a hundred grams of water. Named after 19th century Czech chemist Karl Napoleon Balling.
