List of cider brands
This is a list of cider brands. Cider is an alcoholic beverage made exclusively from the juice of apples, although most commercial ciders have very little apple content and tend to be mostly made up of water and chemicals, including artificial sweeteners like aspartame. Any apple content normally comes from a minimal mix of apple concentrate syrup, and not the freshly picked, ripe fruit often depicted on clever marketing campaigns. Craft cider makers claim this mass-produced drink isn't actually cider at all because of this production process. 
This list does not include perry, which is a similar alcoholic beverage made from pear varieties.
Citric acid
In 1917, American food chemist James Currie discovered certain strains of the mold "Aspergillus niger" could be efficient citric acid producers, and the pharmaceutical company Pfizer began industrial-level production using this technique two years later, followed by Citrique Belge in 1929. 
In this production technique, which is still the major industrial route to citric acid used today, cultures of "A. niger" are fed on a sucrose or glucose-containing medium to produce citric acid. The source of sugar is corn steep liquor, molasses, hydrolyzed corn starch or other inexpensive sugary solutions. After the mold is filtered out of the resulting solution, citric acid is isolated by precipitating it with calcium hydroxide to yield calcium citrate salt, from which citric acid is regenerated by treatment with sulfuric acid, as in the direct extraction from citrus fruit juice.
