The worst I've tried so far has to be the vile fluid that was in the Fifty-One carto's that I started with. Looking back, I see that it was pretty rank - but oddly enough, it's that very fluid that started me on the vaping path. Nasty as it was, it was still better then an analog I guess.
Most tobacco flavors won't taste like tobacco for a couple of reasons, not the least of which is that people naturally want to compare it to the taste of an analog burning. That, as a standard, fails on a couple of points - Primarily the fact that the 'flavor' is produced by combustion and the resulting chemicals. What they grind up and stuff in a paper tube and call tobacco is another.
I'm not at all surprised at the mention of a floral or soapy taste, and yes, even the dirty socks comparison makes sense.
Different tobaccos have very different flavors. Add to that, the way a tobacco is cured will have a profound effect as well.
What most people don't know, and would have no way of knowing, is that there are many tobaccos that actually do have a very floral, soapy scent, and taste that way when burned as well. A lot of people like it. Why they like it has remained a total mystery to me, but they do. It's referred to as 'Lakeland' and comes from the UK. Samuel Gawith and Gawith & Hoggarth are the most well known 'brands'.
Lakeland leaf covers the soap/floral side of thing - now how about the one that Cyberpixie mentioned... My first thought when I read that was 'Oh no - they have "Mixture 79" in liquid form'. Her description of the taste of that stuff is spot-on. It's another that has been around for a long time, over 70 years actually. Masochism is alive and well.
