Thanks to the 'heads up' from this site, I grabbed a few bottles of O'Hara's leann folláin from Superquinn, Sundrive last evening.
It's certainly not a robust, earthy, roasty stout with much coffee flavours. To me, it is more of a milk stout but without the sweetness. It certainly has chocolate as a primary taste and is super smooth to drink. I quite liked it.
