Cask: Regular.
Production moved to Burtonwood, Summer 2007. Subsequently moved to Camerons. Heineken announced that production of cask Magnet would be discontinued in January 2010.

It appears that a keg version of Magnet, also brewed at Camerons, may still be in production. The keg version has a separate listing.

If you’re lucky enough to find one of the selected outlets that sell it then why not try a John Smith’s Magnet.
It has a subtle balance of bitter-sweet flavours; caramel and a hint of liquorice... look why don’t you just try it for yourselves. Easy-drinking, full-flavoured and full-bodied (4% ABV).
