Maybe the URL should also go under the "supporting........" on the coloured side of the card in similar sized font.
I also found the use of Union odd. The word seems serious and nearly archaic nowadays and doesn't sound inviting if we'd like to attract new members. Suggestions: club, group, beer fans, beer lovers. "Ireland's beer fans maintain a directory....." "come and join us!"
Maybe replace the qr code real estate with the twitter and Facebook handle? Does anyone use qr codes?
