Re: Milk consumption?
"I'd really like to know how exactly the UK consumers have changed their habits."
Packaging. Factories/bottling plants are built to produce goods for their customers. Some of that is retail for the likes of you and me, some of it is for "trade" and comes in much larger packaged quantities. Most milk for the trade is in a plastic bag with a spout inside a large box, rather like those boxed wines you see in some supermarkets. Likewise, flour and the current "shortage". People are buying more retail items of both but the retail packaging plants can't keep up with demand. So, at the point of production we have oversupply because trade sale of dropped through the floor but in the retail market we have increased demand above the level of supply. Retail milk no longer seems to be a problem and the flour "shortage" seems to be easing a bit now. Packaging plants are adapting.
Morrisons supermarket are manually re-packaging bread flour from their bakery 16KG sacks into 1.5KG portions using bags from the pie and pasty counter to help meet demand. If you ask nicely they may sell you a 16KG sack or there may even be some on the shelves. The bakery counter will also sell you fresh yeast for 20p. Fortunately, the milk is no longer an issue. I don't feel like going back 60 years and going out with a jug to get some milk!
