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.
Cider
The acids in cider play a vital role in both the cider making process and in the final flavour of a finished cider. They are present in both apples and cider, and add a sour taste and a pungent odor to these respective substances. Acids also serve as a preservative in the cider since microbes grow less in lower pH environments and contribute to the fermentation process. Most ciders have a pH of between 3.3 and 4.1. The primary acid found in apples is malic acid which accounts for around 90% of the acid content in apples. Malic acid contributes to the tart and sour flavours found in cider, and typically between 4.5 and 7.5 grams of malic acid per liter of cider is preferred. Malic acid is also used to determine apple ripeness for harvesting, as its concentration decreases as the fruit ripens. Lactic acid is also commonly found in cider, and it is mainly formed from malo-lactic fermentation, a process that converts malic acid into lactic acid. This process rounds out the flavour of the cider while reducing a lot of the acidity and producing carbon dioxide as well. Other acids such as citric acid can be used to add taste after fermentation, but these acids are not typically found in high concentration in apples naturally.
