Bought 12 x 440 ml cans of Tesco Premium Lager instore for £7.59. Says on the can produced in Netherlands and is 5%. A bit of web research shows it to actually be Grolsch. It does indeed taste exactly the same. Now I know this is a regular price, but a branded product in an own-label can. At 63p a can I reckon that's good value. 4 cans are £2.64. Maybe there should be a thread for own-label stuff, that is actually something more expensive? Money saver!
The image is old style can from Tesco website. New style are red and white cans.
