I flavoured my second batch with anise and licorice, so that flavouring dominates. My first batch was not flavoured. I will grab a pinch right now and give you my impression:
Nose out of the jar is big, fermenty burley, chocolate, with some ammonia still there. This has been in the fridge for 19 days now.
Flavour is salty chocolate, with a slight floral geriniol overtone. Bit of leather. Lovely tingle from the nicotine.
I love it, and I like the ammonia too. So much that I also put a bit of ammonium chloride in my second batch. A Dutch/Scandinavian, salmiak kinda jam.
I am going to snus my Harrow Velvet, Little Yellow and One Sucker, if I succeed in curing them. Looking forward to sharing my impressions.
