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

674 views

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?

Dairy farms collect the milk from all their cows and mix them together to get a consistent, homogenous product. In fact, they will intentionally add cows of different breeds to their herds to alter the properties of the milk. Some breeds of cattle produce milk with higher butterfat percentages, others produce milk with more lactose, etc.

Oh wow. The unpasteurized milk craze in Schitt’s Creek makes sense now. I wanna go to a milk bar after your description!

A bottle of milk typically mixes the milk of thousands of cows, so the flavor becomes indistinguishable. Also, the milk is pasteurized for safety which may alter the flavor.

All the milk gets tested, brought to bottling and distribution, it gets combined into large vat of 1000s of cows, separated into milk fat and milk, then re mixed and tested to create skim 1% 2% and whole, or made into other products. So at one point you have skim milk and buttermilk, and then they will mix it back together to have accurate fat percentages.

Each cow has different fat content in milk, and mixing into a large batch and separating is the only way to ensure that the product that hits the shelves is a consistent product. Otherwise you are trying to balance percentages of each individual cow. Also the milk is easier to store in large vats to transport and bottle, so it isn’t going from teat to gallon jug, it goes teat to milk tank to processing to bottling to jug.

On Facebook there is Iowa Dairy Farmer who does a lot of great explanations of the dairy process.

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.

In Germany you can buy milk from cows fed with hay and cows fed with flowers/grass — tastes a bit different for sure!

The milk in bottles isn’t the milk of just one cow. In fact, it could be a mixture of the milk of thousands of cows.

I remember as a kid drinking milk everyday at school, there was always a day in the spring when all the sudden the milk tasted weird because the cows had started grazing on the new grass after a winter of just hay and feed.

If one dude nuts in a jar and you drink it, you’re tasting some guy’s cum. If a thousand dudes nut in a jar and you take a sip, well that’s just cum in general.
