No, no no.

A common misconception by some people is that beers like Tetleys smooth and the like are real ales, this is untrue and these are what are called Nitro Keg beers.
These kegged beers are pasteurised at the brewery killing any live yeast and then sealed in pressurised kegs. These have a lot longer shelf life than real ale so can be made in large batches and stored for a long time before needed. The trend these days is to not only inject them with carbon dioxide (a natural gas created by brewing beer) but also nitrogen. This makes the beer have a smooth and creamy head giving it a Guinness like consistence. Pubs also now like to serve these beers extra cold .These processes make the beer undrinkable. Large breweries do this for a number of reasons, one of the reasons is it lasts longer meaning they don't have to worry about stock levels and it is a lot easier to handle (pubs can have kegs of it in their cellar for a long time and then just connect the gas and pump to it when required.

Hope this helps.
