"sugary or gritty"? What would make it like that? I've heard a tale of scum mixing ground glass with weed and telling the Chavs they sell to that it's crystals of heroin or Coke, but then the press always blow these thing out of proportion to try and make cannabis look the same as hardcore drugs.
I'm no expert of the numerous strains of weed, but would some like Bubblegum or Strawberry cough not have a sweetish taste?
I do know that the grower (assuming it local grow) can make a big difference to the final taste by doing things like flushing with just water in the final stage of blooming,choosing the right time to harvest and then the conditions they dry it in.
Just some of my random thought for the thread.
All the best to everyone here.
