What grade of fresh milk is it?

Because fresh milk is high-end milk, it is known as "Hermes" of milk.

Biru fresh milk comes from 2,000 Holstein cows in New Zealand. It is rich in milk sources and semi-free-range pasture, maintaining the natural flavor of milk. Low-temperature pasteurization retains more nutrients, especially phosphorus and selenium that are not available in vitamin B and UHT milk, which is more conducive to human health. The factory wholly owns the pasture and controls the whole process from feeding to milking to ensure the freshness and nutritional value of the milk source.

So it is one of the high-end milk in terms of grade.
