Learn why your milk tastes like yogurt due to bacterial fermentation and how to properly store it to avoid sour flavors.

385 views

Your milk tastes like yogurt primarily due to bacterial activity. Milk contains lactose, a type of sugar, which certain bacteria can ferment, producing lactic acid. This gives the milk a sour, yogurt-like flavor. Improper storage at warm temperatures can accelerate this bacterial growth. To prevent this, ensure your milk is stored below 40°F (4°C), and always check the expiration date before use. If your milk consistently tastes off, consider examining your fridge's temperature settings or the source of your milk.
