Glass bottles were phased out in the 1980/90's in Dublin. Deliveries used to be done by the milkman who would leave fresh bottles of milk and remove the empties. As supermarkets began to open earlier and close later - as well as stay open on Sundays the role of the milkman became defunct. Milk also began to be sold in cartons (tetra pak to start with) which I presume was more cost effective.
Adare Farm have just started selling milk in glass bottles again in certain shops. When I saw it on the shelf in Superquinn Ranelagh I had to buy it! The milk looks so good - so tasty and fresh looking. It's also way colder than milk from the carton.
Although more expensive, I think it is worth it.
What way is your milk sold? Glass, carton or plastic bottle?
