Guess what? You're smoking tobacco, its supposed to taste like tobacco, you're doing it right.
The nuance thing will come with time. What others taste is not what you're going to taste, taste is subjective.
Tobacco is kinda like apples. There are dozens of types of apples...Granny Smith, Macintosh, Fugi, Pink Lady.....but they all taste like apples. Can you tell a Gala apple from a Northern Spy apple? Apple aficionados can. And with time and a lot of apples, so could you.
In my opinion tobacco reviews are a huge detriment to new smokers. People think they aren't doing it right if they can't taste "damp grass" and "Georgia red dirt" in their tobacco.
Good tobacco hits everyone different.
Does Cilantro taste good to you, or does it taste like soap? It tastes like perfumed soap to me, my wife loves it. If the only thing you ever taste is tobacco, you're lucky. THAT'S the point of smoking TOBACCO! If you start tasting 40 different flavors, its probably leftover flavors from your lunch. Tobacco will taste different while, or after eating or drinking certain things. I know pipers who only like certain blends with certain drinks. Like Virginia Flake with black coffee, or a Latakia blend with a single malt scotch. The flavors people are tasting are more of impressions than actual flavors. Some straight Virginias give me a cinnamon flavor, ive never heard anyone else say that. Does that mean everyone else is tasting wrong? Or am I tasting wrong, even though I LOVE the taste?
My advice is to pay almost zero attention to tobacco reviews. Anything more than price, moisture content, cut and presentation and an overall impression is just subjective fluff.....in my opinion.
