Bought this a while ago and didn't open it. Not long ago I added half of that small bottle to my fermentation bin of Richies Stout. And boy o boy o boy. Does that stout now have something excellent to it. I tried a vanilla stout a few months ago in Wetherspoons and I can say what I did the other day with this stuff, it brought many memories back. Wasn't that expensive but a worthy pitch to a brew in my opinion.
