No surprise that St.Mel's are making good stuff as Liam had already proven himself with Leann Folláin. Don't think they're at the RDS this year are they?
I think in terms of world class it's a lot easier for a brewery from any nation to achieve success. Any brewery can, in theory, access the best hops, malt and yeast. All they have to do then is get someone who knows what to do with them. (I make it sound so easy)
