I'm reviewing that list as part of a project I'm working on, (adding from other sources as well). My list may contain some breweries that haven't opened yet (and I haven't yet pull the data to differentiate these), but here's the numbers:
Craft Breweries (Ireland): 48 (including 15 contractor brewers)
Craft Breweries (N. Ireland): 12 (including 3 contractor brewers)
Non-craft Breweries (Ireland): 7 (including 3 contractor brewers)
Non-craft Breweries (N. Ireland): 1 (including 1 contractor brewer)
