Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Beer

The term beer includes alcoholic drinks produced by the fermentation of sugars derived from grains of barley, wheat, sorghum, maize or rice.

Brew kettles

Apparatus in which the wort is boiled.

Caramel/black malt

Malt which has been sufficiently heated to caused sugars to caramelize.

Fermentation

Process whereby yeast converts sugar to ethyl alcohol.

Germ

The germ is the shoot which has started to grow from a grain.

Immobilized yeast

The yeast is absorbed on a material instead of being dispersed in the liquid.

Low alcohol

This is beer which has a lower alcohol content than would be expected from complete fermentation of the wort.

Malt

Malt is the term used for partially germinated and subsequently dried grains in which part of the starch has been converted to sugar.

Mash

Mash is a mixture of malt and water. Mashing refers to the process of extracting the sugars from the grains, often at elevated temperature.

Pitching

This is the process of adding yeast to the wort.

Steeping

Soaking the grains in water primarily to stimulate germination.

Wort

Wort is the liquid part of the mash which is left after removal of the insolubles
