This is Sadhbh from The White Hag. Though very much built for the session at only 4.1% ABV it comes in small cans and is quite a pleasingly dark shade of red with a wholesome dusting of haze. The aroma is not that of a bland watery red, with rich and sweet caramel, some milk chocolate and an intriguing Christmassy spice. As expected it's quite full-bodied, which gives it a warming roundness that belies the strength. The sweet side is more subtle than I was expecting, a flash of fudge, but nothing lasting. Instead, the dominant feature is in the finish: a dry green bite of old-world hops, a little metallic and a little grassy. I would guess an English variety.
The overall effect is properly interesting. While this isn't a different style pretending to be an Irish red ale, there are distinct signs of the relationship to UK bitter. As such it would definitely work better by the pint.
