Barm, also called ale yeast, [1] is the foam or scum formed on the top of a fermenting liquid, such as beer, wine, [2] or feedstock for spirits or industrial ethanol distillation. It is used to leaven bread , or set up fermentation in a new batch of liquor.
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Bière de Garde is a hybrid beer whose name translates from French to English as “Beer for Keeping”. The ale is low to moderate in esters and contains a similar malt sweetness to most other ales. The ale's ABV ranges from 4.4% to 8% and has a range of appearances, with its primary descriptions being “Light Amber, Chestnut Brown, or Red.”
Yeast flocculation typically refers to the reversible clumping together (flocculation) of brewing yeast once the sugar in a wort has been fermented into beer. In the case of "top-fermenting" ale yeast (Saccharomyces cerevisiae), the yeast creates a krausen, or barm on the top of the liquid, unlike "bottom-fermenting" lager yeast (Saccharomyces pastorianus) where the yeast falls to the bottom ...
Old School RuneScape is a massively multiplayer online role-playing game (MMORPG), developed and published by Jagex.The game was released on 16 February 2013.

Conversely, ale yeast is best used at temperatures from 55 to 75 °F (13 to 24 °C). Fermentation by ale yeasts produces a beer that has a more distinct flavor. Steam Beer uses bottom fermenting lager yeasts at ale temperatures, which results in a very distinctive flavor profile that includes both ale and lager characteristics.
Many beer styles are classified as one of two main types, ales and lagers, though certain styles may not be easily sorted into either category.Beers classified as ales are typically made with yeasts that ferment at warmer temperatures, usually between 15.5 and 24 °C (60 and 75 °F), and form a layer of foam on the surface of the fermenting beer, thus they are called top-fermenting yeasts.
Analysis of the yeast cultivated from Maier's beard showed that it was a new strain, perhaps a hybrid incorporating genes from Rogue's house yeast called "Pacman". [ 1 ] [ 4 ] [ 10 ] Beverages produced with local American native yeast are collectively known as the American wild ale style, of which Beard Beer is an example. [ 11 ]
