%age butterfat can be anywhere between 4 and 6, I think, maybe more, depending on feeding, stage of lactation, breed, individual cow, etc etc. Hillie sometimes gives me over 1" of cream on a standard 1L jug. At one point it was 2" !
Tesco sell cheap milk so don't have to worry about flavour.
I could use more words but that's the message
Organic cows will be on a more natural diet, and getting plenty of outside on grass time. Cheap milk comes from cows all over the place on all sorts of regimes, including 'zero grazing' 24x7 indoor cows etc etc. And unless it says otherwise, quite possibly not all from Britain either.
I can taste the sugars rising in the grass in the milk from my Jerseys, and BH is now used to getting some of his grass quality information from me, based on the quality, quantity and taste of the Jersey milk.
