Eli5: If the milk of each cow is unique, how come all milk bottles of a brand taste the same?

Question

I remember tasting milk of many cows in my family farm. Each cow had a “signature” taste and part of the experience of drinking milk was enjoying the different tastes. The taste of milk of one single cow depends on many factors: age, diet, health, etc. Then, how do companies standardise the taste of their bottled milk? Best case scenario I can imagine is that producers blends the milk of many cows, but this is definitely no guarantee of a standardised taste. How is this achieved?

Because it’s pumped into silos containing milk from a LOT of other cows. Then they add water/ cream depending on the type of milk they intend to sell i.e. full fat, semi skimmed etc . Source- used to work in the laboratory for Unigate Dairies.
