500ml bottle from Reakt. Massive thanks to Ang for this. Marble Stouter stout was my beer of the festival at Reading so I was really looking forward to this. Plus having seen Mes_and_Sim’s rating of the cask version in Manchester. This, however, is full of diacetyl. Not sure which I dislike more, diacetyl or Islay whisky cask beers. Choc ginger butterscotch is an odd aroma. Bitter choc comes through which is good. Could be good but the diacetyl ruins it. Will re-rate if I see it again. Re rate at Chris o 2011 pre gbbf shindig. Good black malts lovely stout fullness in mouth. Lovely choc. Gorgeouz beer.
