We often waste milk by failing to judge correctly whether it’s sour or not. To stop this misuse UK based dairy Cravendale has created a new type of milk jug.

A unique PH sensor has been placed into its bottom, which can clearly detect the PH acidity of your milk. By using this jug you can test your milk before you throw it into your trash can. The outside this jug has a LCD display which reflects the result (sour or fresh). If you don’t see the message then you will get the sound of an alarm, which helps you know the result.

There is no recent news whether this unique jug is in production or not, however when it comes in mass production then it will definitely help you to know the condition of your milk before having it. Sour milk has a real horrible taste.
