Well think of it this way. Wine can be $10 a bottle, $10 a glass or $10,000 a bottle and it is pretty much just a name to those who don't know the intricacies of wine and who only drink it for flavor and for its obvious intoxicatingly effects. Most people won't care if someone says 'oh that's a 1973 chateau bordeou yada yada blah blah blah if all they are trying to do is have a nice meal or something. For weed conouseurs they say it is this special strain because it is literally a years long process of perfecting one single strain to yield a high amount of THC or the other cannabinoids and crossing perfected Indica and Sativa types will yield a special strain and give it a different look like "Blueberry" or "White Widow" and a different taste and also different effects for those who are that much into weed. For me I have always been a very rare user of weed except when I wasn't but my two main guys always had really good stuff, usually Sour Diesel or Kush variety. To me I knew good from bad and that was pretty much it. I knew good price from bad price so being in New York on Long Island and paying $30 for an 1/8 oz for some "Kush" or "Sour D" is a great price. If I were someone else, like some friends, they would be saying "use a vaporizer and buy the oil or wax and it has this much THC for $80". For me I do not drink expensive wine (I like $15 Korbel Rosé or $45 Vivo Cliqué Yellow Label Champagne) so it does not matter, so long as it gets the right effect, for the right price, and that's pretty much it. But different strains are the end product of long term bioengineering that growers and farmers have used for millenia, in the past crossing their heartiest wheat with their most bug resistant wheat, and for weed it is the ones with the highest THC and usually the biggest buds (yield), but the look and smell never hurt either. So long as the price stays sane. But being that the process is just long and not expensive to make these hybrid strains the price is usually close and now with dispensaries they will go off THC content, other Cannabinoid content, weight and whatever is trending to set the price and what they have in stock.
