Appearance: Yep. Looks like stout. Very very dark brown with thick, persistent tan coloured head kicked up using the syringe trick.
Smell: Very mild, slightly sweet, with no detectable hops. This yeast seems quite subdued, in terms of the aroma. (Guest taster describes slight milky/vanilla/marshmallow)
Taste: Again subdued. Slightly roasty, but I would have liked more oomph. Imagine a very mild vanilla-choco-frappucino. Some classic british ale type sweetness in there, though no dark crystal flavours.
Overall: No flaws, but there’s just not enough there to be great. This probably goes back to the milling issue on brew day. I wouldn’t change the proportions in the grain bill at all, but I would scale it up by a factor of 1.2 or 1.3, and mill the dark grains separately using an extremely tight gap.
