I have been burning some Black Velvet I got many years ago. Just bought a 250g bag from Smokingpipes and opened it yesterday.
The original was quite sweet smelling in the tin and nearly all black leaf from the process they used. It was probably around 15-20% Latakia.
This new blend is mixed light and dark leaf and smells very smokey / English in the tin and is 50% Latakia from the Dan website.
The original had a very smooth but thick mouthfeel and a rich flavor in the mouth with a very pleasant room note for others.
The new one is a lot drier in the mouth and while still an enjoyable smoke, is not nearly as flavored as the original. The room note is disappointing in comparison , but not awful or completely off putting.
I will post some comparison pictures of the tobacco and label, so you know what to look for. I was fantastically lucky and my local shop has some of the old blend left, which I am going to grab a bunch of today. This may be the case in your area if you like or want to try the original.
