Blending tobacco can be tough to get right. I've created some unsmokable abominations in my attempts. I now stick to amending existing blends to tweak them to my preference.I've tried that with latakia but seemed to come unstuck more often than not. Maybe because when I started out I bought a load of loose pure latakia and tried it straight and didn't like it. It wasn't the smokiness more a medicinal astringency I found off-putting, But occasionally when I got it right it added a nice spicey kick to the bland blends I started out with.
Bought a tin of Peterson's 965 today and didn't expect to like when I opened the tin. I'd read description which put the latakia in the background but it definitely isn't. Or at least not to me. I find it quite robust, however there's a nice natural sweetness in the background from the virginia and it's working rather well as an evening smoke. I'm trying it in a Vauen Mokka which I don't otherwise smoke much and I must say it's growing on me.
To my taste, latakia (especially in higher quantities) imparts a fragrant, incense-like smoke to a blend. I've never found it medicinal, but taste is highly subjective. Then again, I've sipped plenty of Islay peated whisky in my time, and never found it to be medicinal tasting, either.
I still haven't tried MM 965, though I have a tin in my stash. It's definitely one I'm looking forward to cracking open.
