It's hard to say unfortunately, despite being a Lat bomb. This will probably not be helpful but I find that Latakia has very interesting behaviour, percentages are not to be taken as exact science:
- low % (5-10%), it adds some little smokiness and generally elevates the main player
- mid % (30-40%), it adds leather and smokiness but not overwhelming, that's when a blend becomes a "Lat blend but not Lat bomb" for me
- high % ( 50% plus) it dominates the blend and makes it very creosoty and oily, which I've come to not like
- 100% - yes I've smoked straight Latakia to see what it's like: it seems (to me) to lose the creosote/tar taste and bring out more of the Oriental/Turkish leaf characteristics which it's made of:
Probably it'd be good to hear from other experienced members what their take on how Lat's impact of blends change with %.
Sutliff pure Latakia tastes/smells like musty old wood barrels and a horse and cow barnstall's overripe hay to me, not incense or curry. I don't like it, so I can't call it savory either. It feels that if I were living on a farm it would blend in with the farm's smells fine enough that it would smell normal to me. A couple strong Latakia Englishes like Star of the East smell like that to me.
A friend with Sutliff pure Latakia and another company's pure Latakia said that Sutliff pure Latakia had that barnstall smell but the other company's Latakia was milder and different, and sounded like it smelled better.
There is a line of Englishes like Gaslight and Squadron Leader where the smell is like a horse's old leather saddle. I don't really like the smell either, and can't call it incenselike or curry or savory. But it's better than the barnstall flavor in Sutliff pure Latakia.
Then there are blends like Walnut MATCH where the Latakia is so slight that maybe it adds character to the blend without making it smell like a barnstall.
So I come away agreeing with your characterization, but with some critiques/qualifications. One is that there is a difference in smell between Latakia brands. Another is that I don't get incense from the Latakia that I tried, except for some Latakia blends like Fr. Dempsey that have a borderline incense smell for me.
So to get back to your main point, you said that you get an incense feeling from Byzantium, and that it's a Lat bomb, and that you think the incense part is from the strong Latakia, although you don't get an incense taste from the Latakia. So I'm trying to zero in more on how you have an incense feeling but not a taste. By comparison, Fr. Dempsey has a borderline incense smell for me and reminds me of incense, whereas Sutliff's pure Latakia had no incense smell and didn't remind me of Latakia. Maybe Sutliff's Latakia could remind me of incense in the sense that they can be both heavy bodied.
