Buttermilk is a term used to describe two types of fermented milk products: traditional buttermilk and cultured buttermilk. Both types of buttermilk are made from cow's milk. The final product has no alcoholic content.

Traditionally, buttermilk has been the liquid left over after producing butter from cream during the churning process.[1] It has a slightly sour taste since the liquid has been fermented by naturally occurring lactic acid bacteria found in raw milk.

In more modern times, commercially available buttermilk sold in supermarkets is instead cultured buttermilk, that is, milk to which lactic acid bacteria have been added to simulate the traditional product. During the 1910s, this product was called artificial buttermilk, to differentiate the product from natural/ordinary/traditional buttermilk.[2] The sour taste, or tartness of cultured buttermilk is a result of a fermentation process in which the bacteria turn lactose into lactic acid. As the pH drops in this reaction the milk becomes tart. At this point, casein, a milk protein, precipitates as it is no longer soluble under acidic conditions, causing what is called clabbering or curdling. The acidity of buttermilk inhibits bacterial growth, and this gives it a long refrigeration life. Sour cream is made using a similar process but uses cream instead of milk.

Traditional buttermilk is quite different from cultured buttermilk: it is thin and slightly acidic, while cultured buttermilk is thick and tart.[1]

Buttermilk Summary
Names Description
buttermilk
traditional buttermilk,
old fashioned buttermilk,
natural buttermilk,
ordinary buttermilk
Thin liquid left over from producing butter from cream.
buttermilk,
cultured buttermilk,
fermented buttermilk,
artificial buttermilk
Thicker liquid produced from bacterial fermentation of milk.


In baking, regular milk can be substituted for buttermilk by adding 1 tablespoon of lemon juice or vinegar or 1 3/4 teaspoons cream of tartar per cup of regular milk. Allow the soured milk to stand for ten minutes before adding to recipes.[4] This method can be used with soy milk or rice milk for vegan/vegetarian consumption.

This is usually made by inoculating skim milk with a culture of lactic bacteria, either our native Bact. lactis acidi, or one of the imported species, such as Bact. bulgaricum. ... In making artificial buttermilk, the skim milk is frequently pasteurized in order to get rid of the miscellaneous flora which it contains. The finished product, therefore, differs from ordinary buttermilk in the fact that it contains nearly pure cultures of the lactic organisms while the natural buttermilk will contain a more or less miscellaneous flora in which the acid organisms predominate. It is possible to obtain a more uniform product iri the artificial buttermilk than in the natural product, and this is perhaps responsible for the rapid development of this industry.
