Still Spirits Top Shelf Bourbon Essence Flavours 2.25L

Initially I used this as directed. And was disappointed by the flavour. Which was weak to say the least. So already having potentially wasted a bottle of neutral spirits, and thinking I might not do the same again, I kept adding this until it approximated bourbon. Which happened to be half way down the next mark which indicates how much to add to a 70cl bottle. So I'd say you can make two bottles not three as stated. Not a bad taste once you get the dosage right . But still more like generic off brand than top shelf. Decent with cola not great straight
