Hi Ravabelli, I've just bought Wilkos velvet stout, putting treacle sounds nice, how much did you put in? Did you make the full 40 pints or did you brew short? Also is the included yeast adequate or would you recommend another. Sorry for all the questions but this is only my second brew my first wilkos hoppy copper being a complete disaster.I've still not made mine given the comments, but as well as what you propose try adding black treacle - it's done wonders for my wilko velvet stout I tasted last night.
Cheers
