The can is almost entirely red, which is doing something simple and effective: it matches the liquid. Tizer pours a vivid red and the packaging commits to it fully, with the wordmark and the slogan "The Great British Pop" picked out in white and yellow against it. The 69p is printed directly onto the can as a price marked pack (PMP), a format fixed at manufacture rather than set by the shop, used heavily in convenience stores where impulse buying decides everything.

The most datable thing on the can is the small word Barr. AG Barr bought Tizer in 1972 for £2.5 million but left its own name off the packaging for nearly forty years. That changed with the 2011 relaunch, which introduced the current logo, the Great British Pop strapline and prominent Barr branding for the first time in the brand's history. Anything with Barr on the front is therefore 2011 or later.

Before that, Tizer was a far stranger thing. It was stylised as T!zer from 1996 to 2007 and fronted by a mascot called Ed the Head, dropped in the 2007 relaunch. It sponsored ITV's CD:UK from 1999 to 2003 in a deal worth £500,000, backed The Chart Show and the MTV Europe Music Awards, and put its name on a rollercoaster at Pleasureland Southport called the TRAUMAtizer, which was billed as the tallest and fastest suspended looping coaster in Europe. When the park closed in 2006 the ride was moved to Blackpool and renamed Infusion.

Inside is a sparkling mixed flavour soft drink, citrus with red fruit and a sharp finish, made with sugar and sweeteners including acesulfame K, with no artificial colours or flavours. It is produced at Westfield in Cumbernauld, the same Scottish plant that makes IRN-BRU, and sold in 250ml bottles, 330ml and 500ml cans, 500ml and 2 litre bottles, and a 750ml returnable glass bottle.
