Finally took my XL23 for a walk loaded with Dunhill Nightcap (I think that tin is nearly 10 years old now).
The flavor here is more like pressed black tea than my preferred musty and savory Latakia/Oriental blends, which is in line with other reviews of Nightcap so I doubt this tin has changed too much (jarred after opening, don't trust the tins).
As usual with Dunhill tobacco it's a nice thin cut and burns wonderfully, though this tin was nearly dried out when I opened it, so now that I've re-hydrated the tobacco we'll see what that does to the flavors next time.
Definitely heavy N, I couldn't finish the bowl (also dieting today so not much food to counter).
