Not sure if you were looking for feedback but here goes...
Well done and a good song, The Fields of Athenry. I've never actually seen it written in it's Irish form. I'm not entirely sure how they fit on a bottle but perhaps "Ath Na Riogh" would fit nicely if it were larger and "Irish Red Ale" could flow smaller under it. The archaic font may be a bit hard to read as is and I can see the words having the potential to just run together as is. You could even set "Irish Red Ale" in a more basic serif font to contrast.
Perhaps on the side panel you may want to put a pronunciation in parenthesis as well.
Just some thoughts.
