Buttermilk  refers to a number of dairy drinks. Originally, buttermilk was the liquid left behind after churning butter out of cream. It also refers to a range of fermented milk drinks, common in warm climates where fresh milk would otherwise sour quickly.

Whether traditional or cultured , the tartness of buttermilk is due to the presence of acid in the milk. The increased acidity is primarily due tolactic acid, a byproduct naturally produced by lactic acid bacteria while fermenting lactose, the primary sugar found in milk.

As lactic acid is produced by the bacteria , the pH of the milk decreases and casein, the primary protein in milk, precipitates causing the curdling orclabbering of milk. This process makes buttermilk thicker than plain milk. While both traditional and cultured buttermilk contain lactic acid, traditional buttermilk tends to be thinner whereas cultured buttermilk is much thicker.
