Describe a brewing process where only malt grist is used and no malt extract is added.
Describes beer made with malted barley and no adjuncts.
Bottle-conditioned: Commercial beers, on the most part, are carbonated with CO2 but bottle-conditioned beers are carbonated by an additional fermentation in the bottle where an extra amount of yeast and little sugar are added. You can usually tell just by looking at the bottom of your beer bottle, if “stuff” is floating around on the bottom, it probably means it’s a bottle-conditioned beer and what you see is left over yeast which in most cases you want to discard, except for wheat beers. Don’t forget the swirl your wheat beer before pouring it though.
A gas created from the fermentation process which results in carbonation.
This is the same as bottle conditioned only it is done in casks.
Is when beer is filtered to remove sediments and contaminants making beer clearer.
The process of yeast consuming soluble sugars in wort to create by-products such as alcohol, carbon dioxide, flavor and aroma.
Finishing/Final Gravity (f.g.)
When the wort ferments, yeast converts maltose into alcohol and the gravity drops because alcohol is lighter that water. Before beer begins to ferment brewers take an original gravity reading (o.g.) once it has fermented the final gravity is taken (f.g.).
Literally, “crown” in German. Introducing unfermented wort to fermented wort to continue or revive fermentation.
Malts are germinated cereal grains that have been dried so to be used in beer brewing
Sugar derived from malt. It is also a fermenting ingredient.
Is the porage-like blend of water and grist at the beginning of the brewing process like oatmeal. Its where the sugar is released.
Original Gravity (o.g.)
See Finish/Final Gravity (f.g.)
A cardboardy or vinous flavor in beer that is the result of the beer being exposed to oxygen for too long.
Much like milk, this process invented by Louis Pasteur is the process where heating beer after fermentation will kill remaining live yeast and bacteria and as a result, will reduce the risk of contamination and/or spoilage.
Specific Gravity (s.g.)
It is a measure of wort’s density in relation to the density of water, which is given a value of 1 at 39.2 degrees F (4 degrees C).
A brewing process that combines both malted grist and malt extract.
Beer is called “wort” before yeast is added.
The science of fermentation.
