Tizer is a red-coloured soft drink bottled in Cumbernauld and sold in the United Kingdom. The name originally comes from the phrase 'Tizer the Appetizer'. It was launched in 1924 by Fred and Tom Pickup of Manchester when it was known as 'Pickup's Appetizer'. After the death of Pickup it was owned by the Armour Trust before being sold to the Scottish drinks company A.G. Barr plc for £2.5 million in 1972. As is the case with Barr's other famous drink Irn-Bru, Tizer's exact recipe has not been made public, although a list of ingredients and nutritional data is given on the product's packaging. In 2003, Tizer decided to sell other-flavoured versions of Tizer, such as "Purple" and "Green" versions. There was also a brief "fruitz" variation of Tizer in 2004. From 1996 to 2007, Tizer was stylised as T!zer. Tizer was traditionally drunk by adding about 4 parts water to every 1 part of tizer., but is now exclusively sold at normal concentration as a fizzy, carbonated drink in cans and bottles.
In 2007 they stopped using "Ed the Head" mascot. Tizer was re-branded with the slogan 'Original Great Taste' and a classic Tizer recipe with fewer additives and no E numbers. It was also given classic 1976 style packaging. However, despite the relaunch making great play of the addition of real fruit juice and the absence of artificial flavourings, colourings and sweeteners, the recipe was reverted in 2009 to remove the real fruit juice and reintroduce natural flavourings, natural colours and sweeteners ( Acesulfame-K). Tizer was rebranded in 2011 with a new logo and the slogan "The Great British Pop".
Tizer sponsored a roller coaster in Southport called the 'Traumatizer'. The ride was closed with the park in 2006 and relocated to Blackpool Pleasure Beach, where it became known as Infusion.
