Isn't Bud American and fosters aussie, albeit made in the UK somewhere. In did watch something about made in Britain or visit the factory that followed beer production at one of the biggest breweries in UK based in Wales that made beer for pretty much most of the nastiest lagers sold in the UK. Chances are bud, fosters and possibly Tennant could be made there on the quiet.
I live in Cumbria, there's more than enough good breweries nearby to avoid the likes of cheap/ nasty lager. BTW is skol made still? When you leave Cumbria for Scotland you tend to have to live with dropping your standards with beer!
