On the company’s webpage it says:
“Through careful herd management and more hygienic milking practices, we begin with healthier cows, then our high quality milk goes directly from cow to bottle. After sealing the bottles, they’re placed under extreme cold water pressure, via a patented, world first, cold pressing technique that is equivalent to taking the milk six times deeper than the deepest part of the ocean. This eliminates any harmful bacteria, whilst being gentler on milk’s nutrients – thus retaining more of milk’s natural goodness. The result is a milk that’s deliciously creamy and as close to drinking milk direct from the cow as you can get.”
