Alex,
First of all I'd like to say the sticker is way over the line and don't agree with it at all. I'm sure you guys can rise above it. Given you've chosen to address it on a discussion board however, I said I'd throw my piece in.
You all seem like great guys who are working really hard, so I'm not going to write anything here I wouldn't want say to your face.
To be frank, the brand is really awful. The standard response seems to have being well, these things are subjective, it's not for everyone, etc. But I don't believe this invalidates the premise, at all. As an Irishman, and beer drinker, I find the brand very insulting, patronising, and playing to lazy stereotypes. Petty stickers aside, I don't seem to have been alone in this view.
Secondly, it's been highlighted by many independent reviewers that the quality of McGargles is simply not very good (not speaking for other rye river brews which have fared better). Again, you're free to say you don't care, but going by the post, it's clear you guys care quite a bit. So why not take some of the advice on board, maybe crank the price by even a euro or two, and make some adjustments? You can still make great tasting session beers for the new craft drinker, without offending the aesthetics of a community who are so passionate to see the craft beer market in Ireland moving to the next level.
I hope this didn't come across as too harsh, and I wish yourself and the rest of Rye River every success.
