Boulevard Irish Ale is available in Boulevard variety packs. If you go to a store with a good sell through of variety packs you can find it. It's a bit of a lottery though, some packs will have Nutcracker (which, I like better, but I have sixers of it) and others will have Irish.
We had a nice Irish Christmas last year as we randomly bought a variety pack that had Irish Ale in it. I think it was Stella's favorite part of Christmas last year.Sixers of Irish won't be available for a couple of weeks. So if you're an Irish Ale lover, go find yourself a variety pack.
