UPDATED: AUG 9, 2017 Irwell Works Marshmallow Unicorn, 4.4% - on tap at the GBBF at Kennington Olympia, 2017. Jet black. Weak and nondescript aroma, a bit grainy, a bit of molasses, a hint of coffee. Rather light bodied, watery. Mildly sourish-sweetish start of liquorice and citrus, with a dry bitter, chocolaty blanance. Middle is lickerish with a burnt malt side note, then it gets drier and drier in the finish and aftertaste, of dark cocoa. Very dry as you keep drinking. Good. ThreeCats (1027) - ISRAEL - AUG 8, 2017
