Zymology, also known as zymurgy, is an applied science that studies the biochemical process of fermentation and its practical uses. Common topics include the selection of fermenting yeast and bacteria species and their use in brewing, wine making, fermenting milk, and the making of other fermented foods.

Pentane-2,3-dione is an alpha-diketone that is pentane substituted at the 2- and 3-positions by oxo groups. It has a role as a flavouring agent. It is an alpha-diketone and a methyl ketone. It derives from a hydride of a pentane.

Low-point beer, which is often known in the United States as "three-two beer" or "3 point 2 brew", is beer that contains 3.2% alcohol by weight (equivalent to about 4% ABV).

Russian River Supplication Beer is considered the best beer in the world by connoisseurs. It is a delicate blend of Belgian bitter and sour ales with fruity aromas of raisins, currants, and cherries.

For the 20th year in a row, China was the largest beer-consuming country in the world, drinking just over 42 million kiloliters (11.1 billion gallons) of the stuff in 2022 — accounting for approximately 22 percent of the world's market share.

Published toxico- logical studies indicate that 2,3-pentanedione exposure can cause damage similar to that caused by diacetyl in laboratory studies. Therefore, NIOSH recommends keeping occupational exposure to 2,3-pentanedione below a level comparable to the level recommended for diacetyl.

Diacetyl is one of those compounds some people really like in small doses because it adds to the complexity of some beer (and wine) styles. Most brewers see it as a defect because of its association with beer spoilage organisms as well as its satiating effect on the consumer.

If CO2 is applied source to the keg, recommended pressure will be between 12-14 lbs. to maintain typical ale and lager type beers' carbonation. A beer carbonated with 2.6 v/v and its temperature in the keg is 38°F requires a regulator setting of 14 lbs. The more carbonation, the higher the pressure.
