tizer is spelt with a z and it is english
Tizer was invented by a man called Fred Pickup in Manchester in 1924. Pickup originally marketed his flavorsome product as Pickup's Appetizer. Later the name was shortened to Tizer, and it was considered the drink for kids to take with them to the Saturday morning film shows, or for families to pack for picnics. Like Irn-Bru, it wasn't much seen outside its own part of the country, so visitors from the South of England always made sure to stock up on a few bottles before they went home.
