Welcome along PJames .
I'm a Cork based homebrewer too , Doing all grain . If you're interested , you can get base malt local alright but as yet there are no Bricks and mortar places . Limerick and Waterford each have small shops . Depending on what you're looking to do I know places to get some things around ( if you're gonna do any DIY Stuff like a keggle or wort chiller )
Happy brewing !!!
