11% of barrel aged barley wine by Siren. It's one of their annuals, 2018 being the year they put it into barrels, so it's this year's version. Drinking it at room temperature because I discovered that when I had a sample at the brewery this year it had already warmed up a little, which really brought out the flavour. It's a very winey barley wine and warmed up tastes almost like a fortified wine. I may put my remaining bottle in the fridge for an hour and see how it tastes when it's cooler but not cold.
