I was in the middle of making dinner when this happened. I’m grateful I poured it into a measuring cup first. Thankfully I don’t live too far from another source.
I remember milk staying good almost a week past its expiration date when I was a kid. Boy have the times changed.
In the UK we have (in UK pints, 1 pint = 568ml): 1 pint, 2 pints, 4 pints and 6 pints. We also have slightly smaller metric sizes (1L, 2L) that are typically seen in convenience stores or on branded milk.
I would say that 4 pints (2.273L) is the typical size that most would buy for regular use, with smaller sizes popular for those that don’t have cereal/porridge. I find that milk from the supermarket tends to keep well, so it’s not that difficult to get through a 4 pinter, unless all you use it for is adding some in your tea - in which case you can just get a 1 or 2 pint jug.
We use it for drinking directly from a glass. Typically about 1 dl per children’s glass, 2 dl or so per adult glass. So do that once a day, that’s 2.8 litres a week for us. That makes 2×1.5 L/week enough. One gallon for one person is a lot of milk IMO but people obviously manage. I just find it baffling to consume that much. 😄
