Go to
www.tobaccoreviews.com to get some idea of a blend [Personally I've learnt to trust
@jiminks reviews in particular]
Buy an ounce each of as many different genres as your budget allows.
Jar them. They will keep for decades - some blends, Virginia in particular, get better with age.
There's no such thing as 'too much' tobacco. It will always hold it's value and if crap ever hits the fan, it would be an excellent trade item.
Stock up while you can.
I've also found that many blends taste so much better a week after opening the tin or pouch.
Never ever throw out tobacco. Your tastes will change. Like many smokers I started with aromatics then turned off them for a while, preferring non-aromatics and English or American blends.
Once one understands ones preferences, one learns how to adjust a blend by adding a straight leaf like Virginia, Burley, Oriental, Perique or Latakia or by mixing one blend with another to suit ones particular taste.
After 10 years of smoking a pipe I now like to smoke a little of everything depending on my mood [Except for heavily flavoured gloopy aromatics that is]
There's a few things that improve ones enjoyment that you'll learn over time; learning to pack different cuts just right and moisture level for example.
With time and patience it becomes 2nd nature.
My experience learning how to pack was like most others; now I pack a bowl without giving it much thought.
It also takes time for your palette to adjust. Given time you will start to taste the different flavours.
Enjoy and welcome to the Brotherhood of the Briar.
