This has been a recurring theme for me for the last couple of visits to Against the Grain. The irish beers on tap have an unpleasant aftertaste, it is difficult to describe it fully but it occurs towards the end of the taste, it seems chemical in nature, sulphury springs to mind.. I have steadily worked my way through most of the taps that they have in there and I get this taste on the Irish Draft beers not on the Cask, Bottle or Foreign Draft. E.g. I love Howling Gale Ale in Bottle and on Cask but find it undrinkable on Draft. Has anyone else experienced the same?
The Beers I have tried where I get this taste
Howling Gale Ale
Galway Hooker Pale Ale
Oharas Irish Pale Ale
Tom Creans Lager (particularly bad)
Trouble Brewing Or
So I guess that begs the question is it something to do with the way the pub itself is serving the beer? CO2, pipes etc?
or could it be the process of kegging has allowed something to creep in intentional or no.
