Wow! 8 litres is a lot of surplus milk!
I'm talking about Meiji Fresh Milk - comes in 2L bottles, Full Fat and Low Fat (dark blue and light blue tops). Not baby formula - so-called "FRESH" milk. They do have flavoured varieties (choc, coffee, strawberry, in smaller bottles). Hubby seems to think it's ok and he delivered milk in UK when he was a lad - grew up on "green top".
