I think that all beer festivals should sell only obscure, rare and one-off ales. When there are hundreds of tasty real ales on sale why do they pander to people who drink tasteless lager ? As for the inclusion of foreign beers (excepting Scotland and Ireland of course!). These are not “proper” beer so why are they included?
Don’t get me started about those other drinks not made from the grain of the barley. Who would think of crushing apples and pears and leaving them to rot for several months then drinking the effluent that they produce!
