Beer from A to Z
The optional description of this glossary.
A
Alcohol Content
In beer, the alcohol content is determined by the amount of fermentable sugars present in the wort and how completely those sugars are converted by the yeast during fermentation. Once the alcohol is produced, it must be measured. Analyzing a beer’s alcohol content is an important part of laboratory work—both for quality control and legal compliance. The average beer typically contains between 4.8% and 5.2% alcohol by volume (ABV), though it’s common to find beers ranging anywhere from 3% up to 15%, and occasionally even higher.
Ale
Top-fermented beers. The yeasts used in the production of these beers have a faster fermentation process than those used in lagers and at higher temperatures, between 16º and 24º. This often gives ales a more fruity and complex flavour.
In the glass, it takes on a colour that varies from amber to coppery. Clear and bright.
On the nose, the aroma is rich in malt. The hop notes are less noticeable, with a more spicy and floral flavour.
In the mouth, the malty flavours are dominant. Some examples have a malt character ranging from caramel to biscuits. There is also a strong hop bitterness, which makes the finish more balanced.
Altbier
Traditional beer style from the city of Düsseldorf, Germany.
It is an Amber Ale in which the bitterness of the hops and the intense character of the malt are well balanced.
Classic examples of this beer can be found in Altstadt, the old town of Düsseldorf.
American Amber Ale
American craft beer with the aromas and flavours of New World hops, with notes of malt and caramel. Originating in Northern California, its name began to be used by American microbreweries around 1980: first as a simple commercial designation, but later as a style.
American IPA
A style that emerged around the 1970s due to American breweries' interest in craft styles. It was created to revive the original India Pale Ale from England, which had fallen into decline.
It is a beer in which the flavours of American hops stand out.
American Lager
A light Pale Lager, slightly bitter and with a mild flavour. The modern version was influenced by Prohibition and World War II, when brands sought to create a beer that would appeal to a large part of the population.
Its origin is inspired by European Pilsner, brewed by German immigrants since the 19th century. However, it is less hoppy and less bitter than traditional Pilsners.
American Pale Ale
A product of the growth of craft breweries, it was inspired by English Pale Ale, but without sacrificing local ingredients: hops, malt, yeast and water.
Techniques such as late hopping and dry hopping, combined with the use of local hops such as Cascade or Centennial, give the beer citrus, floral or fruity aromas and flavours.
Antioxidants
They play two essential roles in beer: they prevent oxidation of the wort, yeast and the drink itself, increasing its shelf life, and at the same time have a positive effect on the health of those who drink it.
Antioxidants come from malt and hops, and the amount varies according to the style produced.
