You taste lactic acid when the milk becomes sour. Acids, in general, sour.
Curd generally has a tangy and slightly sour taste due to the fermentation process that transforms milk into curd. Additionally, the taste can vary depending on the type of milk used and the fermentation time.
Milk tastes sweet primarily due to the presence of lactose, a natural sugar. When milk is fermented to make curd, bacteria convert lactose into lactic acid, which gives curd its sour taste. This fermentation process not only changes the flavor but also alters the texture and nutritional profile of the milk. Thus, the sweetness of milk and the sourness of curd result from different microbial activities and chemical compositions.
When excess curd is added to milk, the lactic acid bacteria present in the curd ferment the lactose in the milk, leading to the production of more lactic acid. This process thickens the milk, causing it to curdle and form a thicker yogurt-like consistency. If left for too long, the excess acidity can result in a sour taste and further separation of whey from the curds. Ultimately, the milk transforms into a more tangy and thicker dairy product.
Rotten fruit or spoiled milk can have a sweet smell but taste sour when consumed.
Sour milk typically has a pH around 4.4 to 4.8. The presence of lactic acid produced during the fermentation process contributes to the decrease in pH, giving sour milk its characteristic tangy taste.

they put some kind of bacteria probably YEAST
A bacteria called lactobacilus converts lactose into Lactic acid thus making it sour. Lactic acid buildup due to bacterial activity causes the pH of the milk to drop. Once the pH drops below pH 4.6, the casein proteins coagulate and forms a curd. The curdling is due to the milk becoming sour.

Acetic Acid
Curd is the coagulated part of a liquid, the part of milk which coagulates when it becomes sour.
Buttermilk is a cultured dairy product made by adding lactic acid bacteria to milk, giving it a tangy flavor. Sour milk is milk that has naturally soured due to the presence of bacteria, resulting in a more acidic taste. The main difference is that buttermilk is intentionally cultured, while sour milk occurs naturally through spoilage.
The curd is the fat in the milk that sticks together. ------------------------------------------------------------------- I think it is the proteins rather than the fat that are responsible for the formation of curd - after all you can get fat free curd cheese.
Lemonade or vinegar are examples of foods that have a sour taste.
the sunlight will make the milk be gushy and then it will taste like sour milk

Curd contains live bacteria that continue to ferment the milk sugars even after it has set. If the curd is not transferred to a cool place, the bacteria will continue to multiply and produce more lactic acid, causing the curd to become increasingly sour.
