Don't believe us? Well think about this. A 3.41 litre bottle of milk costs around £1.68. That latte you're drinking might have 250ml of milk in it, for arguments sake, costing 12p using these numbers. The coffee at many establishments is likely to be costing around £5.50 a kilogram. It is unlikely that more than about 14g of coffee used to make your latte, so that gives us a cost of 8p per cup. That's why we call it coffee flavoured milk! The vast majority of the coffee offered for sale is so poor that people have taken to drinking it with large quantities of milk and sugar to make it more palatable.
