  2. Beer chemistry - Wikipedia

    en.wikipedia.org/wiki/Beer_chemistry

    This means that the beer has smaller bubbles and a more creamy and stable head. [6] These less soluble inert gases give the beer a different and flatter texture. In beer terms, the mouthfeel is smooth, not bubbly like beers with normal carbonation. Nitro beer (for nitrogen beer) could taste less acidic than normal beer. [7]

  3. Gravity (alcoholic beverage) - Wikipedia

    en.wikipedia.org/wiki/Gravity_(alcoholic_beverage)

    For example, OG 1.050 is roughly equivalent to 12 °P. By considering the original gravity, the brewer or vintner obtains an indication as to the probable ultimate alcoholic content of their product. The OE (Original Extract) is often referred to as the "size" of the beer and is, in Europe, often printed on the label as Stammwürze or sometimes ...

  4. Saccharomyces cerevisiae - Wikipedia

    en.wikipedia.org/wiki/Saccharomyces_cerevisiae

    Saccharomyces" derives from Latinized Greek and means "sugar-mould" or "sugar-fungus", saccharon (σάκχαρον) being the combining form "sugar" and myces (μύκης) being "fungus". [3] [4] cerevisiae comes from Latin and means "of beer". [5] Other names for the organism are: Brewer's yeast, though other species are also used in brewing [6]

  5. Attenuation (brewing) - Wikipedia

    en.wikipedia.org/wiki/Attenuation_(brewing)

    In brewing, attenuation refers to the conversion of sugars into alcohol and carbon dioxide by the fermentation process; the greater the attenuation, the more sugar has been converted into alcohol. A more attenuated beer is drier and more alcoholic than a less attenuated beer made from the same wort.

  6. Beer head - Wikipedia

    en.wikipedia.org/wiki/Beer_head

    The carbon dioxide may be produced naturally through the activity of brewers yeast, or artificially by dissolving carbon dioxide under pressure into the liquid. The beer head is created by the carbon dioxide produced as a byproduct of the metabolism of brewer's yeast acting upon starches and sugars found in the wort.

  7. Beer fault - Wikipedia

    en.wikipedia.org/wiki/Beer_fault

    Oxidised beer has the moldy taste of old newspapers. Beer with 100% oxygen exposure has the fastest oxidation rate. Temperature is another cause of oxidation, as it produces a lot of oxygen in a high-temperature environment. [12] To avoid excessive beer exposure to oxygen, the headspace reserved for the beer in the bottle should be less than ...

  8. Ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Ethanol_fermentation

    Fermented: Beer; Liquors: Whiskey, and sometimes vodka. Gin and related beverages are produced by the addition of flavoring agents to a vodka-like feedstock during distillation. Rice grain starches converted to sugar by the mold Aspergillus oryzae. Fermented: Rice wines (including sake) Liquors: Baijiu, soju, and shōchū; Sugarcane product ...

  9. Beer - Wikipedia

    en.wikipedia.org/wiki/Beer

    Old English: Beore 'beer'. In early forms of English and in the Scandinavian languages, the usual word for beer was the word whose Modern English form is ale. [1] The modern word beer comes into present-day English from Old English bēor, itself from Common Germanic, it is found throughout the West Germanic and North Germanic dialects (modern Dutch and German bier, Old Norse bjórr).
