OK I have one batch in the pressure barrel and another in bottles (that batch is too new to taste). Made them the same, as described above.
This is very very similar to the bottled Mann's Brown Ale. So it's OK, very drinkable, but nothing special.
Colour: dark
Head retention: not wonderful but OK.
Flavour: a hint of sweetness (that could be the food grade LME I added) and also a hint of bitterness. No hoppiness to speak of. The flavour is average (it does not taste weak/watery, but not heavy/strong either).
