Yes MB perfumes aren't very intense or long lasting.
Try Poivre ny Caron. It skews towards the clove end of the spectrum but falls within the pepper genre.
Then of course theres Bang and Opus 1870 and Poivre Samarcande.
My wife got me a bottle of the shower gel as a gift, the scent is great!. So.... I thought I would investigate the EDT as well. I tried it at the local Molton Brown boutique but unfortunately the longevity was more along the lines of an After Shave...the scent is captivating though.....
I agree with Hendonist, Hermes Hermessence Poivre Samarcande is really an excellent example of what you are looking for. There's also LeLabo Poivre 23.
I really like MB Black Pepper - when I wear it I also wear the matching deo. At least, I feel like I'm getting some longevity from it that way.
I use the body wash, but that's where I stop. Bracing Silverbirch is nice too.
