I think its as simple as this: some judges picked 15 different bottled beers and they're all on sale now. The two best-sellers get permanently stocked in Sainsburys. This seems a little unfair as without buying them all you're somewhat going on the nice labels and the store's one-line description. I picked the St Peters Amarillo purely because I know and generally like St Peter's beer (and the flask bottle is a nice shape). TCMJ picked the Old Tom with Ginger because she likes ginger beer (and probably also because it has a picture of a pussy cat). So you rather think this is a marketing competition rather than a beer one. You can read more about the contest here:

But all of this is just warm-up for the most exciting discovery on the shelf. I like my darker beers so was naturally attracted to a stout. And it had a picture of a dog on it, for it was Crazy Dog Stout. I'm also always keen to support the local brewers, and this came from just neighbouring Suffolk. It would have gone in the basket at this point. But the icing on the cake: it is brewed by TONY HADLEY OUT OF THE SPANDAU BALLET.
A bit of googling reveals he's a real ale man - he's an investor in the Red Rat Craft Brewery which produces Crazy Dog, and he even opened the East Anglian Beer Festival. The EADT reports:
Hadley's picked up four awards from the Campaign for Real Ale in as many weeks, including two golds: champion bitter at Colchester Beer Festival and best beer under 5% at the East Anglian Beer Festival. In August the brewery is in Sainsbury's beer competition finals and Crazy Dog Stout will be on sale nationally in its main stores.
And the bottle comes complete with photo and signature:

Mr Hadley's beer goes under the Jackson taste test tonight.
When's the "Gold" golden ale out? And what next - Limahl's Lager?
